Introduction

Use this guide to replace the user interface on a GE dishwasher model GDT545PSJ5SS. The user interface, also called the button panel or control panel, lets you choose cycles and send commands to the control board. Replace it if the panel stays dark, the buttons don't respond, and testing shows the control board is still sending power to the interface. Other GE dishwasher models may use a similar assembly, but the jumper settings, wiring, and screw locations can differ.

What you need

Step 1 Disconnect power and open the lower access area

Turn off the dishwasher breaker before touching any wiring.
Use a screwdriver to remove the two screws securing the kick plate.
Set the kick plate and the strip of noise dampening foam aside.
Use a voltage detector to confirm the dishwasher power is off.
Remove the screw securing the junction box cover, and set the cover aside.

Step 2 Lower the control board tray

Use a screwdriver to remove the two screws securing the metal control board tray.
Lower the tray enough to access the control board and its connectors.
A clear photo or simple sketch of the tray and connectors can help during reassembly.

Step 3 Test control board output

Turn the breaker on only for this voltage test.
Keep your fingers on the insulated probe handles and don't touch exposed metal contacts.
Set a multimeter to measure DC volts.
Locate the row of five pins on the control board.
Place one multimeter probe on pin 5 and the other probe on pin 2.
A reading of about 14 volts DC means the control board is sending power to the user interface.
A lit green LED on the control board also suggests the board is working.

Ask FixBot

Step 4 Interpret the test result

If the board LED is on and the pin test reads about 14 volts DC, the user interface is the likely failed part.
If the green LED is off or the pin test doesn't show about 14 volts DC, troubleshoot or replace the control board instead.
Turn the breaker off again before continuing.
Raise the control board tray back into place.
Use a screwdriver to reinstall the two screws securing the control board tray.

Step 5 Disconnect the user interface harness

Disconnect the wiring plug that runs from the control board to the user interface.
Use a socket wrench to remove the two screws holding the door to the hinges.
One hinge screw is on the far left, and the other hinge screw is on the far right.
Look under each hinge area for the two small hinge-lock holes.

Ask FixBot

Step 6 Lock the hinges open

Insert an Allen wrench into the hinge-lock hole on one side.
Open the door until the hinge holes line up and the Allen wrench holds the hinge open.
Repeat the same process on the other hinge.
The hinges are spring loaded and can snap shut after the door is removed.

Step 7 Remove the door

Rock the door back and forth gently to work it free from the hinges.
Don't pull the door away quickly, because the wiring is still zip tied to the dishwasher.
Use snips to cut the zip ties holding the door wiring.
Cut only the zip ties, not the wires.
Lift the door away from the dishwasher.
Wear work gloves if the sheet metal edges feel sharp.

Step 8 Separate the door halves

Use a screwdriver to remove the two screws that join the door halves.
Remove the small vent cover from the door.
Press down on the handle while lifting the inner half of the door.
Separate the plastic outer door piece from the metal inner door piece.

Step 9 Remove the user interface assembly

Disconnect the cable that comes from the control board to the user interface.
Use a screwdriver to remove the four screws securing the user interface assembly.
The two far-end screws are shorter than the two middle screws.
Slide the user interface assembly out of the top of the door.
Keep the screw locations organized so the long screws return to the center holes.

Ask FixBot

Step 10 Remove the old user interface board

Use a small Phillips screwdriver to release the plastic clips around the user interface housing.
Pry the two housing halves apart as each clip releases.
This clip-release process is fiddly, so work slowly and avoid snapping the plastic tabs.
Lift the old user interface board out of the plastic housing.
Keep the failed board separate from the new board so you don't reinstall the bad part.

Ask FixBot

Step 11 Configure the new user interface

Use the personality configuration sheet that comes with the new user interface.
Find the dishwasher model number on the sheet and match it to the correct jumper positions.
For model numbers beginning with GDT545, use personality number 14.
Set jumpers 8, 4, and 2 to closed, and set jumper 1 to open for a GDT545 configuration.
GE uses this user interface across several dishwasher models, so incorrect jumpers can make buttons perform the wrong labeled functions.
Compare the jumper positions on the board to the diagram on the sheet before installing the board.

Ask FixBot

Step 12 Reinstall the user interface assembly

Place the new user interface board into the plastic housing.
Set the button piece back onto the housing.
Press the housing together until all the clips snap into place.
Slide the user interface assembly back into the top of the door.
Use a screwdriver to reinstall the two long screws in the center holes.
Use a screwdriver to reinstall the two shorter screws in the outer holes.
Reconnect the wiring to the user interface.

Ask FixBot

Step 13 Reassemble the door

Align the teeth on the plastic door piece with the grooves in the metal door piece.
Slide the plastic door piece down into place.
Use the vent opening as an alignment check.
Use a screwdriver to reinstall the two screws holding the door halves together.
Reinstall the vent cover and tighten its screw.

Ask FixBot

Step 14 Reinstall the door on the hinges

Work the door back onto the hinges, adjusting the angle until it seats correctly.
Keep the Allen wrenches in the hinge-lock holes until the door is back on both hinges.
Remove the Allen wrenches from both hinge-lock holes after the door is seated.
Reconnect the user interface wiring to the control board.

Ask FixBot

Step 15 Test the repair

Turn the breaker on and confirm the user interface lights up.
Press the buttons and make sure the dishwasher responds.
If the panel stays dead, turn the breaker off and recheck the user interface plug, control board plug, and pin test result.
If the buttons work but don't match their labels, turn the breaker off and recheck the personality jumpers.
Turn the breaker off again before securing the lower covers.

Ask FixBot

Step 16 Secure the lower hardware

Use a socket wrench to reinstall the two screws that secure the door to the hinges.
Reinstall the junction box cover and tighten its screw.
Reinstall the noise-dampening foam strip.
Reinstall the kick plate.
Use a screwdriver to reinstall the two kick plate screws.
Turn the breaker back on after all covers and screws are in place.

Ask FixBot

Step 17 Run a test cycle

Start a dishwasher cycle and confirm the dishwasher fills, washes, and responds to the controls.
Run a few normal cycles before calling the repair complete.
Watch the hinge area for loose wiring if the door movement feels unusual.
Recycle the old user interface board according to your local e-waste rules.

Ask FixBot

Conclusion

The user interface is replaced once the panel lights up, the buttons respond correctly, and the dishwasher completes normal cycles. Repair didn't go as planned? Ask our Answers community for help.
