Lg Dishwasher Control Panel Malfunctions
Within the realm of LG dishwashers, control panel malfunctions can sometimes disrupt the seamless operation of your appliance. Let’s explore the underlying causes and their effective solutions.
01 – LG 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.)
02 – LG 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.)
03 – 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.
04 – 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.
05 – LG 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.
06 – LG 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.
07 – LG Dishwasher 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.
08 – 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.
09 – LG 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.
10 – LG 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.
11 – LG 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.
13 – LG 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.
