User Control and Display Board

appliancepartspros

The user control and display board is an important part of the dishwasher that allows users to select the desired wash and dry settings. If you find that some or all of the buttons on the control board are not working, you will need to first check if the control board itself is functioning properly. Look for illuminated indicator lights on the display. If some lights are illuminated or some of the control functions are working, it suggests that the user control and display board may be faulty and require replacement. However, if there are no lights and no functionality at all, it is more likely that the issue lies with the door switch or the main control board.

Repair Steps

1.Disconnect power at circuit breaker. Turn off power for safety before servicing.
2.Remove control panel trim pieces if any. Find screws or clips around edges of trim molding.
3.Note wire connection positions on board. Take photos for accurate reconnection later.
4.Disconnect all wires from old control board. Carefully detach each wire by its connection point.
5.Remove mounting screws securing board in place. Usually 2-3 small screws hold board inside panel.
6.Detach old control board from back of panel. Gently lift out once fully disconnected.
7.Clean mounting area on back of panel. Wipe away any debris from where new board will attach.
8.Mount replacement control board into panel. Set into position and start securing screws.
9.Reconnect wires one by one matching positions. Refer to photos taken earlier for accuracy.
10.Replace any trim pieces removed initially. Snap securely back into their positions.
11.Reconnect power and test functions. Check all controls and display operating correctly.

Control Panel

appliancepartspros

The control panel is the part of the dishwasher that lets you pick how you want it to wash and dry your dishes. If you find that some or all of the buttons on the control panel are not working, the first thing to check is if the control panel itself is working or if the little indicator lights are turned on. If you see that the indicator lights are on or some of the control buttons work, it's possibly a problem with the control panel, and you might need to get it replaced. But if you don't see any lights and none of the buttons are working, it's more likely that there's an issue with a line fuse or the main control board.

Repair Steps

1.Disconnect power at circuit breaker. Turn off power for safety before servicing.
2.Remove any trim pieces around control panel. Find screws or clips securing decorative molding.
3.Take photos of wire connections on back. Note positions for accurate reconnection later.
4.Disconnect all wires from connections on panel. Gently detach one wire at a time by its connector.
5.Remove screws securing control panel in place. Typically 2-4 screws hold panel on inside door.
6.Detach old control panel from inside of door. Carefully lift panel out once fully disconnected.
7.Clean mounting area inside door. Wipe away debris from where new panel will attach.
8.Mount replacement control panel on inside of door. Set into position and start securing screws.
9.Reconnect wires one by one matching positions. Refer to photos for precise wire placements.
10.Replace any decorative trim pieces earlier. Snap securely back into position surrounding panel.
11.Reconnect power and test functions. Check all controls operating as intended.

Wire Harness

Door Switch

appliancepartspros

When the buttons on your dishwasher aren't responding, it might be due to a problem with the door switch. This switch makes sure the dishwasher can't start a wash cycle if the door is open. To find out if the door switch is the issue, you can test the switch for continuity with a multimeter.

Repair Steps

Check Fault Codes

appliancepartspros

If the lights on your dishwasher are flashing or blinking, or if there is a fault code displayed on the screen, you will need to refer to the wiring diagram, tech sheet, and/or user manual for additional details about the specific error. These resources provide valuable information that can help you understand the nature of the problem. By consulting the wiring diagram, tech sheet, and user manual, you can gain insights into the error code and its meaning, allowing you to take appropriate action. These documents offer guidance on troubleshooting steps or potential solutions to resolve the issue.

Incoming Power Problem

appliancepartspros

If your dishwasher doesn't show any indicator lights or make any noise when you turn it on, it's probable that power isn't reaching the dishwasher. To troubleshoot this issue, start by checking the circuit breakers and GFCI outlets (if you have them) to make sure they haven't tripped. Also, inspect any fuses to make sure none are blown. Since most dishwashers are directly connected to the electrical system (not plugged in), it's important to examine the junction box on the dishwasher for loose or burnt wires. Loose or burnt wires in the junction box can disrupt the power supply. You will need to replace any damaged wiring.

in lock mode

appliancepartspros

Several dishwashers include a child lock or a "Sabbath" feature that disables the buttons when activated. It's possible that your dishwasher is currently in "Demo" mode or another mode that limits its functionality. Check your dishwasher's user manual for instructions on how to lock or unlock the control panel. The user manual will provide specific details on how to engage or disengage the child lock or other modes that may be preventing full operation.
