Jenn-Air Dishwasher stops mid-cycle

Jenn-Air Dishwasher stops mid-cycle

Have you noticed that your dishwasher has stopped way sooner than it was supposed to be? Unfortunately, it probably wasn’t because it finished ahead of schedule, but rather because it stopped right in the middle of a cycle. This can leave your dishes dirty or still covered in detergent residue. Whether you try to start the cycle again and get no response or find that the same mid-cycle premature end happens all over again, we can help you get to the bottom of it. So what is causing your dishwasher to stop prematurely before its job is actually done?

Blown Fuse or Thermal Fuse

If your dishwasher stopped prematurely and is now not starting again, it could be as simple as a blown fuse in your fuse box. If your dishwasher has indicator lights on the front, check them for illumination which means there is power to the appliance. If they are not on and no power seems to be flowing to your appliance, you may want to check for a tripped breaker or a blown fuse.

Alternatively, you may also have had the thermal fuse inside your dishwasher blown. Many of your other appliances come installed with a thermal fuse as a safety measure. In your dishwasher, the thermal fuse protects the motor and other working parts of the appliance from extreme heat. When detected, the fuse trips and cuts the power to stop it from getting too hot. Once this happens, as a part with only a one time use, it will need to be replaced. However, if you discover that it is the thermal fuse, replacing it will not do you much good. The only thing that will happen is that it will likely be tripped again. Unlike blowing a fuse in your fuse box, tripping a thermal fuse doesn’t happen randomly. There will always be another cause that needs investigating to stop your dishwasher from blowing another thermal fuse.

Door Latch

If your door latch or the microswitch is going faulty, then it can prevent the operation of your dishwasher. Essentially, as a safety feature, the door latch must be engaged before the dishwasher can be run. If that door latch fails mid-cycle, it will stop the whole dishwasher’s operation. If the door latch cannot be engaged, the dishwasher will also fail to start. Even if your dishwasher door shuts tightly, the door latch may not be engaged. You will want to replace the entire latch assembly if you deem this to be the cause. You can test the door switch by manually activating it, in which case the dishwasher should activate with the door open.

Electronic Control Board

The control board is, as you would expect, the brain of your appliance. While it is designed to last pretty much the lifespan of your dishwasher, things can go wrong and electronic control board can go faulty. When this happens, it can manifest so many different symptoms, and one of them can be cutting the cycle short in the middle. However, if it is the control board that is responsible for shutting off a dishwasher in the middle of a cycle, you will likely notice other problems that manifest as well since it controls almost every aspect.

Pump and Motor

In order to run at all, your dishwasher needs water and adequate water pressure. You should check to see if your home still has water by turning on a faucet briefly. If the water has been shut off due to an outage, then this can cause the dishwasher to stop in the middle of its cycle as it does not have the water it requires to proceed.

However, while your home can lose water connection, it isn’t something that happens all the time. Far more likely is that the dishwasher stops mid-cycle because there is an issue with the pump or the motor. If the motor fails to produce enough water pressure due to malfunction, it may shut off. When a pump or motor failure happens, you will likely notice some louder than normal noise and even some leaking. Shutting off in the middle of the cycle is just one possible symptom, but it is more likely that the dishwasher will just fail to start altogether.

Fan Assembly

There is always the chance that your dishwasher did technically complete the wash cycle, but if you discover that it finished faster than anticipated, it could be that the dishwasher is skipping the drying cycle. This can easily be ascertained since when you open your dishwasher, your dishes will still be quite wet. If you did have a dry cycle activated, you will want to investigated the fan assembly. If the fan no longer functions, the dishwasher can’t ferry out the hot, moist air left after a wash cycle. As such, your dishes will remain wet and it will skip the dry cycle completely.

Alternatively, if you discover that your dishwasher is only cutting off the dry cycle, but the fan is still working, then there are other parts that can go out. One other suspect could be the high-limit thermostat. This is responsible for turning off the heating element so that the dishwasher does not get too hot. However, if it malfunctions, it can turn the heating element off prematurely. This can result in colder temperatures not only during the dry cycle but during the entire wash cycle. If you open the dishwasher during what should be the dry cycle and find things quite cold inside, you will want to test this with a multimeter. Furthermore, you may note that your dishes are not quite clean if it has shut off the heating element during other periods of the wash cycle in the dishwasher.

Jenn-Air Dishwasher has a burning smell

Jenn Air Dishwasher Drain Valve

The drain valve will often use a solenoid to open the valve to allow the water to exit the dishwasher. Since the solenoid is an electrical component, it can short out and produce a burning smell. You should inspect the solenoid for any burn marks near the terminals. You can also use a multimeter to test the drain valve solenoid for electrical continuity to determine if the component is able to function properly. If the solenoid is faulty, the entire drain valve assembly may need to be replaced.

Jenn Air Dishwasher Heating Element

The heating element may be shorted, causing a burning smell. In most cases when the element shorts out, it will have blisters or raised sections on it; in other cases a shorted element will break in half. To determine if the heating element has burned out, use a multimeter to test it for continuity. If the heating element does not have continuity, replace it.

Jenn Air Dishwasher Timer

On some dishwasher models, the timer determines when power is sent to the various components of the dishwasher. If the timer receives a power surge, or a component fails, the timer can short-out causing a burning smell. Inspect the timer for burn marks. A damaged timer will need to be replaced.

Jenn Air Dishwasher Control Board

The control board provides power to the various components of the dishwasher. If the control board receives a power surge, or a component fails, the control board can short-out causing a burning smell. Inspect the control board for burn marks. A burnt control board will need to be replaced.

Jenn Air Dishwasher Pump and Motor Assembly

The circulation pump uses a motor and impeller to force water up through the wash arms during the dishwasher’s wash and rinse cycles. If the motor has burned out or is in the process of failing, it can produce a burning smell. You can often tell that a circulation pump motor has burned out if the motor isn’t making any noise or is just making a humming sound after the dishwasher has filled.

Jenn Air Dishwasher Drain Solenoid Kit

The drain solenoid opens the drain valve to allow the water to exit the dishwasher. Since the solenoid is an electrical component, it can short out and produce a burning smell. You should inspect the solenoid for any burn marks near the terminals. You can also use a multimeter to test the solenoid for electrical continuity to determine if the component is able to function properly.

Jenn Air Dishwasher Main Control Board

The main control board provides power to the various components of the dishwasher. If the control board receives a power surge, or a component fails, the control board can short-out causing a burning smell. Inspect the control board for burn marks. A burnt control board will need to be replaced.

Items on Heating Element

On dishwashers with exposed heating elements, plastic or wood items like forks, spoons, and lids can fall through the racks and onto the element. When the element comes on in the dry cycle the items can melt or burn causing a smell. Remove any items that may have fallen onto the heating element.

Jenn Air Dishwasher Power Cord

If the power connections in the junction box are not secure the wire can overheat, melting the coating on the wires. Check to ensure the connections are tight and not burnt. If the connectors are burnt the wires will have to be cut and reconnected securely.

Jenn Air Dishwasher Control Module

The control module allows voltage to be sent to the various components of the dishwasher. If the control module receives a power surge, or a component fails, the module can short-out or overheat and cause a burning smell. Inspect the module for signs of damage or burn marks and replace if necessary.

Jenn-Air Dishwasher not drying dishes

Jenn Air Dishwasher Vent

The vent might not be opening properly. As the dishes are drying, many dishwashers use a vent to let out the hot, steamy air generated during the rinse cycle. If the vent does not open properly, the dishwasher will leave moisture on the dishes. Check the vent to ensure that it is opening properly.

Jenn Air Dishwasher Turbidity Sensor

A dishwasher turbidity sensor measures the amount of food particles in the water being circulated through the appliance to help determine how long a wash or rinse cycle should last. Some sensors also incorporate a thermistor to regulate the temperature. If the sensor is faulty, it may prevent the dishwasher from entering the drying cycle.

Jenn Air Dishwasher Vent Fan Motor

Some dishwashers use a vent fan motor to help dry the dishes at the end of the cycle. If the fan motor is not working, the dishwasher won’t dry the dishes properly. To determine if the fan motor has failed, test the motor for continuity. Also, try turning the fan blade by hand to ensure that it spins freely. If the fan motor has burned out or the fan blade won’t turn smoothly, replace the vent fan motor.

Jenn Air Dishwasher Heating Element

Some dishwashers use a heating element to heat the dishwasher during the drying cycle. If the heating element has failed, the dishwasher won’t dry dishes properly. To determine if the heating element has burned out, use a multimeter to test it for continuity. If the heating element does not have continuity, replace it. Note that some dishwasher heating elements have a resettable fuse that can trip, preventing voltage from reaching the element to heat it. Pressing the button on the fuse will reset it and restore power to the element

Jenn Air Dishwasher Heating Element Assembly

Some dishwashers use a heating element to heat the dishwasher during the drying cycle. If the heating element assembly has failed, the dishwasher won’t dry dishes properly. To determine if the heating element assembly has burned out, use a multimeter to test it for continuity. If the heating element assembly does not have continuity, replace it. Note that some element assemblies have a resettable fuse that can trip, preventing voltage from reaching the element to heat it. Pressing the button on the fuse will reset it and restore power to the element.

Jenn Air Dishwasher Wire Harness

A wire harness allowing voltage to be sent from the dishwasher control board to a heating element could be loose or damaged and unable to provide power to the element. If this happens, the dishwasher may not be able to dry the dishes properly. You should inspect all wire harnesses for loose connections or damage, especially burn marks near the connection points, and replace if necessary.

Heated dry not selected

Not all cycles are created equal. If the dishes are coming out too wet, confirm the cycle you are using has heated dry or the heated dry option is selected.

Jenn Air Dishwasher Float Switch

The float switch is a safety device designed to shut off the water inlet valve if the dishwasher is overfilling. If the float switch is defective or stuck, it might interrupt the cleaning cycle, preventing the dishware from drying properly. You can use a multi meter to test the float switch for continuity. If the float switch is defective, replace it.

Rinse aid not being used

Although it is not as important as using detergent in the dishwasher, using rinse aid will result in better drying performance. Rinse aid is formulated to help keep the water from adhereing to the dishes and works well on plastic dishware that is often hard to dry. Most dispensers have settings to adjust the amount of rinse aid being used. Consult your owner’s manual for recommended settings.

Jenn Air Dishwasher High Limit Thermostat

The high-limit thermostat monitors the dishwasher internal temperature and shuts off the heating element if the dishwasher overheats. If the high-limit thermostat is malfunctioning, it may shut off the voltage to the heating element circuit. However, this is rarely the case. Before replacing the high limit thermostat check all the more commonly defective parts. If you have determined that all of the other components are working properly, test the thermostat by using a multimeter to test it for continuity.

Jenn-Air Dishwasher overflowing

Jenn Air Dishwasher Water Inlet Valve

The water inlet valve is an electrically-controlled valve that opens to allow water to enter the dishwasher. Depending on the model, the valve stays open either for a set length of time or until the dishwasher has enough water. However, if the water inlet valve doesn’t shut off after the dishwasher has enough water, the dishwasher will overflow. If water drips into the dishwasher when the door is open, or if water collects at the bottom of the dishwasher while it is not use, you may need to replace the water inlet valve.

Jenn Air Dishwasher Main Control Board

A dishwasher’s main control board provides power to nearly every electrical component in the dishwasher. If the control board continues to send power to the water inlet valve during the drain cycle, the dishwasher could overflow. While this is not that common of a problem, you can inspect the board for signs of burning or a shorted-out component. You can also use a multimeter to test the water inlet valve for incoming power during the dishwasher’s cycle.

Jenn Air Dishwasher Lower Wash Arm Assembly

If the lower wash arm has a crack or split on the side it can cause water to splash out the bottom of the door, giving the impression that the dishwasher is overflowing. Inspect the wash arm assembly for any damage and replace if necessary.

Wrong type or incorrect amount of detergent

Make sure to use the proper dishwasher detergent. Use the proper amount of detergent for your water hardness; too much soap in soft water can cause oversudsing and leaking.

Jenn Air Dishwasher Control Board

A dishwasher’s control board provides power to nearly every electrical component in the dishwasher. If the control board continues to send power to the water inlet valve the dishwasher could overflow. While this is not that common of a problem, you can inspect the board for signs of burning or a shorted-out component. You can also use a multimeter to test the water inlet valve for incoming power during the dishwasher’s cycle.

Jenn Air Dishwasher Float Switch

The float switch actuates in order to prevent the dishwasher from overflowing. If the float switch is defective or stuck, it might not stop the dishwasher from overflowing. If the float switch is defective, replace it.

Jenn Air Dishwasher Pressure Switch

A dishwasher pressure switch is the component that will send a signal to shut off the water inlet valve once an appropriate amount of water has entered the tank for a wash cycle. If the pressure switch is malfunctioning, it may fail to signal the inlet valve to close and cause the dishwasher to overflow. You can use a multimeter to test the pressure switch’s terminals for appropriate changes in electrical continuity before and after blowing air into the attached pressure tube. If the switch has shorted or does not test appropriately, it should be replaced.

Jenn-Air Dishwasher making noise

01 – Jenn Air Dishwasher Drain Pump

First, check the drain pump to ensure that it is clear of debris. If the drain pump is clean but it is still noisy, replace it.

02 – Jenn Air Dishwasher Circulation Pump

The circulation pump motor has bearings that wear out over time. When the motor bearings fail, they generate a continuous drone. If the motor bearings have failed, you must replace the entire circulation pump.

03 – Jenn Air Dishwasher Drain Impeller

The drain impeller pushes water through the drain hose and into the garbage disposer or drain line. If the impeller is broken, replace it.

04 – Jenn Air Dishwasher Pump and Motor Assembly

Part of the pump and motor assembly (such as the motor bearings, drain impeller, or wash impeller) might be defective. Often, you can replace the pump’s individual parts. However, if you do not want to disassemble the pump to replace its parts, or if the parts are not available separately, you can replace the entire pump and motor assembly.

05 – Jenn Air Dishwasher Wash Impeller

The wash impeller is a small plastic blade that forces water through the spray arms. If one or more of the impeller blades is broken, the dishwasher will make noise. In addition, if the impeller is damaged, warped, or bent, it can scape against the pump housing. Inspect the wash impeller for damage. If the wash impeller is damaged, replace it. On most models, you can replace the wash impeller independently of the pump and motor assembly. Search for your model number to determine if your impeller is replaceable. If the impeller cannot be replaced separately, you will have to replace the entire pump and motor assembly.

06 – Jenn Air Dishwasher Circulation and Drain Pump Motor

The circulation pump motor has bearings that wear out over time. When the motor bearings fail, they generate a continuous drone. If the motor bearings have failed, replace the motor or replace the entire pump and motor assembly.

07 – Obstructed wash arm

There are several wash arms in a dishwasher, typically one for each rack. If a handle or untensil is sticking through one of the racks the wash arm may be hitting it as it turns. Or there may be an item that is too tall and obstructing the upper wash arm. Confirm that nothing is obstructing the upper or lower wash arms.

08 – Jenn Air Dishwasher Water Inlet Valve

The water inlet valve opens to allow water to enter the dishwasher. When it is new, the water inlet valve is very quiet during operation. Over time, the diaphragm inside the valve deteriorates and deforms. This deformation interacts with the water rushing in and can produce a loud vibration, buzzing, squealing, or other noises. If the dishwasher is loud during the filling cycle, replacing the water inlet valve may solve the problem.

09 – Jenn Air Dishwasher Circulation Pump Motor

If the noise is happening only during the wash cycle, it’s quite likely a worn out circulation pump motor is the cause. The circulation pump motor has an impeller and bearings that can wear out over time. When the motor bearings fail, they generate a continuous drone. If the impeller is broken or damaged, it will produce a grinding noise. If either the bearings or impeller are damaged, you must replace the entire circulation pump.

Jenn-Air Dishwasher won’t fill

Jenn Air Dishwasher Bi-Metal

The bi-metal actuator is a metal loop which acts as a latch for the dispenser door. As electricity is applied to the bi-metal, it deforms and bends away from the latch, releasing it. If the bi-metal is burned out, it won’t release the dispenser door. To determine if the bi-metal has burned out, use a multimeter to test it for continuity. If the bi-metal does not have continuity, replace it. In addition, make sure that the dishwasher is getting enough water. If the water level is too low, the wash motor may not draw enough current through the bimetal, causing the bimetal not to bend enough to work properly.

Jenn Air Dishwasher Dispenser Slide

If the dispenser slide is damaged, the dispenser won’t open or close properly. If the slide is broken or damaged, replace it.

Jenn Air Dishwasher Pump and Motor Assembly

The dishwasher’s pump and motor assembly circulates the water through the wash arms during the wash and rinse cycles. If the pump and motor assembly is defective, the wash cycle may be interrupted and the dispenser will not be activated to release the detergent. In this case, the pump and motor assembly will need to be replaced.

Improper loading

There needs to be adequate space between the dishes and the dispenser. Inadquate space can prevent the dispenser door from opening or prevent water from mixing with the detergent. If a large item is placed in front of the dispenser the detergent will not get rinsed out properly. Leave some space between the dishes and don’t place large plates or pans in front of the dispenser.

Jenn Air Dishwasher Water Inlet Valve

A dishwasher’s water inlet valve opens following a short drain cycle to fill the tank with water in preparation for the wash cycle.

Jenn-Air Dishwasher won’t start

There are several reasons why your Jenn-Air dishwasher not starting or not operating:

control lock is on
dishwasher is in sleep mode
delayed wash option is selected
door is not completely closed and latched
water supply is not turned on
the power needs to be cycled to reset the dishwasher

The control lock is used to avoid unintended use of the dishwasher as well as to avoid unintended cycle or option changes during a cycle, some model have a sleep mode function. The control lock light will stay on for a short time, indicating that it is activated and all buttons are disabled. If any buttons are pressed while the dishwasher control is locked, the light will flash three times. The door can still be opened/closed while the controls are locked.

NOTE: You may need to disable Sleep Mode by pressing either START/RESUME or CANCEL, or by opening and closing the door before you are able to turn the control lock off.

To turn off the control lock feature:

Press and hold the Lock Button for four seconds, the lock light will turn off.

HAS A DELAY WASH OPTION BEEN SELECTED?

A delay wash option runs the dishwasher at a later time or during off-peak electrical hours. If the delay wash has been selected, the dishwasher will not run until the delay time is reached.

To Turn Off the Delay Wash Feature:

Press CANCEL/DRAIN to cancel the delay.
Press START/RESUME to start the cycle.

IS THE DOOR COMPLETELY CLOSED AND LATCHED?

Make sure that the door is completely closed and latched. A lower dish rack that is installed backward can also cause the door to not latch properly.

IS THE WATER SUPPLY TURNED ON TO THE DISHWASHER?

Make sure the dishwasher water supply is turned on. See installation instructions for your model if you are unsure how to check this.

HOW TO RESET THE DISHWASHER:

Much like a computer, resetting the dishwasher control can sometimes solve the issues you are experiencing. To reset the dishwasher control panel, it needs to be disconnected from the power source for one minute. If your dishwasher is plugged into an outlet, simply unplug the unit for one minute and then plug the unit back in. If the dishwasher is hard wired to the power supply, turn the breaker off at the home electrical panel that powers the dishwasher for one minute and then turn the breaker back on.

Jenn-Air Dishwasher leaking from motor area

Jenn Air Dishwasher Shaft Seal

First, try to determine the source of the leak. If the water is leaking from the motor shaft area, the motor shaft seal is likely defective. If the seal is defective, replace it. (Some manufacturers sell the seal independently of the impeller. Other manufacturers require that you purchase the impeller and seal together. Still other manufacturers require that you purchase the entire pump and motor assembly instead of the impeller and seal. It is more cost effective to replace the seal kit rather than the impeller and seal.)

(Some manufacturers sell the seal independently of the impeller. Other manufacturers require that you purchase the impeller and seal together. Still other manufacturers require that you purchase the entire pump and motor assembly instead of the impeller and seal. It is usually more cost effective to replace the impeller and seal kit rather than the pump and motor assembly.)

Jenn Air Dishwasher Seal Kit

Jenn Air Dishwasher Pump and Motor Assembly

If the dishwasher is leaking water from the motor area, the entire pump and motor assembly need to be replaced. First, try to determine the source of the leak. If the water is leaking from the drain pump, the impeller and seal is likely the cause. On most dishwashers, you can replace the impeller and seal kit independently of the drain pump. However, if you do not want to disassemble the pump, or if the impeller and seal kit is not available separately, you can replace the entire pump and motor assembly. In addition, if the motor shaft is rusted and the new impeller won’t fit onto the shaft, replace the pump and motor assembly.

Jenn Air Dishwasher Water Inlet Valve

A dishwasher’s water inlet valve opens following a short drain cycle to fill the tank with water in preparation for the wash cycle. If the inlet valve is cracked or damaged, the dishwasher can leak water near the motor area beneath the dishwasher tank.

Jenn Air Dishwasher Drain Hose

A dishwasher leak near the motor area could be caused by damaged drain hose. Confirm the hose is secured to the drain pump outlet port and check for any cracks or holes in the hose itself. Replace a damaged drain hose with a new one.

Jenn Air Dishwasher Sump

Most dishwasher pumps have a large bowl, or sump, which collects the water that enters the pump. The sump is lined with a rubber seal that prevents water from entering the dishwasher tub. If the sump seal is worn out, the sump will leak water. If the sump seal is leaking water, replace it. In addition, on some dishwashers, a lock ring secures the sump to the bottom of the tub. If the lock ring is cracked or damaged, replace it.

Jenn Air Dishwasher Drain Pump

A dishwasher drain pump assists in removing the water from the tank during the drain cycles by using an impeller to force or push the water through a drain hose to the garbage disposal or a sink drain pipe. If the drain pump is cracked or damaged, the dishwasher can leak water near the motor area beneath the dishwasher tank.

Jenn Air Dishwasher Circulation Pump

A dishwasher circulation pump circulates the water through the spray arms to wash the dishware. If the pump is cracked or damaged, or a seal is worn out, the dishwasher can leak water near the motor area beneath the dishwasher tank.

Jenn Air Dishwasher Diverter Motor

A dishwasher’s diverter motor operates a diverter disc to redirect the water between the upper and lower wash arms. If the stem seal is damaged, it can potentially leak water behind the lower access panel near the pump motor area. If water is leaking from the diverter motor area, the diverter motor will need to be changed.
