Thermador 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.

Thermador 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.

Thermador 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.

Thermador 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.

Thermador 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.

Thermador 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.

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.

Thermador 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.

Thermador 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.

Thermador Dishwasher Water Inlet Valve Issues

Thermador Dishwasher Water Inlet Valve

The water inlet valve opens to allow water to enter the dishwasher. If the water valve is clogged or defective, water will not flow into the dishwasher. Water inlet valves are not repairable—if the valve is defective, you must replace it.

Thermador Dishwasher Main Control Board

A dishwasher’s main control board provides power to nearly every electrical component in the dishwasher. A faulty board may be unable to supply power to the water inlet valve, preventing it from opening and allowing the necessary water to fill the tank.

Thermador Dishwasher Float Switch

The float switch is a safety designed to shut off the water inlet valve if the dishwasher is overfilling. If the float switch is defective or stuck, it might stop the dishwasher from filling correctly. You can use a multi meter to test the float switch for continuity. If the float switch is defective, replace it.

Thermador Dishwasher Control Board

A dishwasher’s control board provides power to nearly every electrical component in the dishwasher. A faulty board may be unable to supply power to the water inlet valve, preventing it from opening and allowing the necessary water to fill the tank.

Water Supply Problem

Over time, calcium deposits can build up in the water supply valve or in the small filter screen inside the water inlet valve. If the water inlet valve is clogged with sediments, the dishwasher won’t fill properly. Before working on the water line, first shut off the water supply. Inspect the valve to determine if it is clogged. In addition, check the water pressure to the valve. The water inlet valve requires at least 20 psi to function properly.

Thermador 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 prevent the inlet valve from opening and filling the tank. 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 does not test appropriately, it should be replaced.

Thermador Dishwasher Electronic Control Board Failures

Thermador Dishwasher Touchpad and Control Panel

First, ensure that the display works. If the dishwasher display is working but the some of the button don’t respond correctly, the touchpad and control panel might need to be replaced. (Some manufacturers sell the touchpad separately from the control panel. Other manufacturers require that you purchase the touchpad and control panel together. If you cannot replace the touchpad individually, replace the touchpad and control panel.)

Thermador Dishwasher Touchpad

First, confirm that the dishwasher display is working. If the display is still working, try pressing some of the touchpad buttons. If some of the buttons respond correctly but others don’t, it is likely that the touchpad is at fault. (Some manufacturers sell the touchpad separately from the control panel. Other manufacturers require that you purchase the touchpad and control panel together. If you cannot replace the touchpad individually, replace the touchpad and control panel.)

Incoming Power Problem

If there are no indicator lights or any noise from the dishwasher when it is turned on, it is likely that power is not reaching the dishwasher. Check the circuit breakers and GFCI (ground-fault circuit interrupter) outlets, if applicable, to confirm they have not tripped, or inspect any fuses to confirm none have blown. Since most dishwashers are hardwired (not plugged in) the junction box on the dishwasher should be checked for loose or burnt wires.

Dishwasher in lock mode

Many dishwashers have a child lock or “Sabbath” feature which will prevent the buttons from being used when the feature is engaged. The dishwasher could also be in “Demo” mode or another mode which prevents full operation. Consult the dishwasher’s user manual for information regarding locking/unlocking the control panel.

Thermador Dishwasher Door Latch

If the dishwasher buttons aren’t working, it’s possible the door latch is malfunctioning and preventing a wash cycle from being started. Inspect the door latch for any damage. you can also use a multimeter to test the micro switch inside the door latch for electrical continuity. If the switch does not have continuity, the switch or latch assembly should be replaced.

Thermador Dishwasher Main Control Board

The main control board regulates nearly every function in the dishwasher. If there is a problem with the main control board, it might not send voltage to the dishwasher touchpad, causing the touchpad buttons not to work. Control boards are often misdiagnosed; make sure you test more commonly defective parts before replacing the main control board.

The control board regulates nearly every function in the dishwasher. If there is a problem with the control board, it might not send voltage to the dishwasher touchpad, causing the touchpad buttons not to work. Control boards are often misdiagnosed; make sure you test more commonly defective parts before replacing the control board.

Check Fault Codes

If the dishwasher lights are flashing or blinking or there is a fault code in the display window, consult the wiring diagram, tech sheet, and/or user manual to find out more information about the error.

Thermador Dishwasher User Control and Display Board

The user control and display board is the component that allows the user to choose a dishwasher’s wash and dry setting. If some or all of the buttons aren’t working, you should first determine if the control works at all or if the display indicator lights are illuminated. If lights are illuminated or some of the control works, it’s likely the user control and display board is faulty and will need to be replaced. If no lights and no functionality is present, it’s more likely a door switch or main control board is at fault.

Thermador Dishwasher Control Panel

The control panel is the component that allows the user to choose a dishwasher’s wash and dry setting. If some or all of the buttons aren’t working, you should first determine if the control works at all or if the display indicator lights are illuminated. If lights are illuminated or some of the control works, it’s likely the control panel is faulty and will need to be replaced. If no lights and no functionality is present, it’s more likely a line fuse or main control board is at fault.

Thermador Dishwasher Door Switch

If the dishwasher buttons aren’t working, it’s possible a door switch is malfunctioning and preventing a wash cycle from being started. To determine if the door switch is at fault, use a multimeter to test the switch for continuity. If the switch does not have continuity, replace it.

Thermador Dishwasher Micro Switch

If the dishwasher buttons aren’t working, it’s possible a micro switch in the door latch is malfunctioning and preventing a wash cycle from being started. To determine if the micro switch is at fault, use a multimeter to test the switch for continuity. If the switch does not have continuity, replace it.

Thermador Dishwasher Drain Hose Blockages

When your Thermador dishwasher experiences drain hose blockages, it can lead to issues with water not properly draining from the dishwasher, resulting in standing water and incomplete cycles. Here’s how to address drain hose blockages:

Turn Off the Dishwasher:
For safety, start by turning off the dishwasher and disconnecting it from the power source.
Check the Air Gap or Garbage Disposal Connection:
If your dishwasher drain hose is connected to an air gap or a garbage disposal, inspect these connections for any clogs or blockages. Clear any debris you find.
Inspect the Drain Hose:
- Carefully remove the dishwasher’s kickplate, which is usually located at the bottom front of the appliance. You may need a screwdriver for this.
- Once the kickplate is removed, locate the drain hose, which is typically a white or gray flexible tube. Check for kinks, twists, or any visible obstructions within the hose. Straighten out any kinks and remove any visible debris.
Check the Drain Hose Connection to the Dishwasher:
Ensure that the drain hose is securely connected to the dishwasher. It should be attached to a drain pump or drain port on the dishwasher.
Clean the Drain Hose:
Carefully remove the drain hose from its connection and place it over a bucket or a shallow container to catch any water. Gently blow air into the hose to dislodge and clear any blockages. You can also use a plumber’s snake or a long, flexible brush to remove debris from the hose.
Clean the Sink’s Drain Line:
Disconnect the drain hose from the sink’s drain line and inspect for clogs. Use a plumber’s snake or a drain cleaning tool to remove any blockages.
Reassemble and Test:
- Reconnect the drain hose, ensuring it’s securely attached, and reattach the kickplate.
- Turn on the dishwasher and run a test cycle to check if the issue has been resolved. Ensure there are no leaks, and the water drains properly.
Regular Maintenance:
To prevent future blockages, it’s a good practice to clean the dishwasher’s filter and regularly inspect the drain hose for any debris or obstructions. Additionally, avoid washing items with food residue or debris that can clog the dishwasher.

If you find that you cannot resolve the drain hose blockage issue or encounter any persistent problems, it’s recommended to contact a professional appliance repair technician. They can diagnose the problem, disassemble and access hard-to-reach areas, and ensure the dishwasher operates efficiently.

Thermador Dishwasher Spray Arm Problems

Spray arm problems in a Thermador dishwasher can lead to inefficient cleaning and may result in residue buildup on your dishes. Here are some common issues related to spray arms and potential solutions to address them:

Clogged Spray Arms:

Over time, mineral deposits, food particles, and debris can clog the small holes in the spray arms, reducing their ability to distribute water evenly. To address this issue, remove the spray arms from the dishwasher and soak them in warm, soapy water. Gently clean out any blockages with a small brush or a toothpick. Ensure that all the holes are clear before reattaching the spray arms.
Broken or Damaged Spray Arms:

If the spray arms are cracked or have broken components, they may not rotate properly or distribute water evenly during the wash cycle. Inspect the spray arms for visible cracks or damage. If they are compromised, they should be replaced with compatible new spray arms from the manufacturer.
Loose or Misaligned Spray Arms:

If the spray arms are not securely attached or are misaligned, they may not rotate as intended, leading to uneven cleaning. Ensure that the spray arms are correctly attached and tightened in place. Verify that they can move freely without obstruction. Adjust or align them as needed.
Defective Spray Arm Support or Bearing Rings:

The support and bearing rings that hold the spray arms in place can wear out or break, causing wobbling and improper rotation. Inspect the support and bearing rings for damage or wear. If they are compromised, replace them with new parts to ensure the spray arms are held securely.
Low Water Pressure:

Inadequate water pressure can result in weak spray arm performance, as they rely on water pressure to rotate and distribute water effectively. Ensure that the water supply to the dishwasher is sufficient. Check for any blockages in the inlet valve or water line, and clean or replace them if necessary.

If you’re experiencing persistent spray arm problems in your Thermador dishwasher, and the DIY solutions do not resolve the issue, it’s advisable to seek professional assistance. A qualified technician can diagnose the problem, replace any damaged components, and ensure that your dishwasher is operating at peak performance.

Thermador Dishwasher Error Code E25

Thermador dishwashers are renowned for their cutting-edge technology and exceptional performance. However, even the best appliances can encounter issues, and understanding and addressing error codes is crucial to keep your dishwasher running smoothly. In this article, we will take an in-depth look at Thermador dishwasher error code E25, which typically indicates a problem with the drain pump or the drain pump cover.

Error Code E25: What Does It Mean?

Error code E25 is your dishwasher’s way of signaling a drain issue. It can be caused by a blocked drain pump or a loose or missing drain pump cover. When you open your dishwasher and find water pooled at the bottom, it’s time to take action.

Step 1: Ensure Safety

First and foremost, prioritize safety. Unplug the dishwasher and turn off the power to the unit to avoid any electrical mishaps. The next step is to remove the water from the base of the dishwasher. If you have a wet vacuum, that’s ideal. However, a turkey baster can also do the job if you don’t have a wet vacuum.

Step 2: Access the Pump Cover

The pump cover is located beneath the dishwasher filter. Lift the spray arm to access it. Gently pull up the filter and set it aside. If you notice any remaining water in this area, remove it as well. Your primary focus here is the pump cover.

Step 3: Check the Pump Cover

Start by checking if the pump cover is loose. If it is, simply secure it in place. Once you’ve done that, attempt to drain the dishwasher. Sometimes, a loose cover can be the root cause of the error code.

Step 4: Inspect the Pump Impeller Spinner

If securing the pump cover doesn’t resolve the issue, it’s time to inspect the pump impeller spinner. To access it, use a spoon to remove the pump cover. The impeller should move freely without obstructions. Debris in this area can lead to drainage problems. When inspecting for debris, it’s advisable to wear thick gloves, as you might encounter sharp objects, such as glass.

Step 5: Remove Debris

If you find any debris obstructing the impeller’s movement, carefully remove it. This can be a common culprit for the error code. Once the debris is cleared, reassemble the dishwasher.

Step 6: Test the Dishwasher

Reassemble all the components, ensuring everything is in its place. Now, try to drain the dishwasher. If the issue was related to the pump cover or debris obstructing the impeller, your dishwasher should operate without error code E25.

In the event that these DIY steps do not resolve the issue, or if you encounter any difficulties during the process, it’s advisable to seek professional assistance. A trained technician can provide a thorough diagnosis and ensure that your Thermador dishwasher operates flawlessly.

Remember that safety should always be a priority when dealing with appliance issues, and when in doubt, it’s best to contact a professional to avoid any further complications.
