What does the F33 error code mean?

The F33 error code on a GE dishwasher usually indicates a door switch error. This means that there may be a problem with the door switch itself or the associated wiring.

The door switch allows the dishwasher to operate when the door is opened or closed. When the door is open, the switch should be open, and when the door is closed, the switch should be closed. Issues with the door switch can prevent the dishwasher from starting or completing a cycle.

Safety precautions

When working on any appliance, remember to keep safety first. Here are some tips to keep in mind:

• Always power off and unplug your appliance or switch off the circuit breaker before you attempt any maintenance or replacement work. This keeps you safe by preventing any risk of electric shock.
• If the appliance has recently been used, give it plenty of time to cool down before working on it.
• Turn off the water supply at the outlet before beginning repairs. Keep towels ready to catch any residual water in the system when removing parts.
• Take your time while working to prevent accidents and personal injuries. Rushing is the enemy of precision.
• Work in a well-lit area so you can see and access appliance parts.
• Keep your workspace free of clutter and other obstacles. Keep children and pets away from the work area.
• Never work on internal parts with wet hands. Make sure the work area is completely dry.
• Check the user manual to see if there are specific installation or safety instructions related to your appliance or replacement part.
• Be gentle when handling or removing parts. Excessive force might damage the appliance or cause personal injury.
• Wear insulated work gloves to protect your hands from sharp metal parts and debris.
• When working with wires, avoid touching any exposed wires or terminals. If you need to touch a wire, use a non-conductive tool or wear insulating gloves to prevent electrical shock.
• Always take photos or make a note of wiring terminals or other connections before disconnecting them to make reassembly easier.
• Don’t test live voltage with a multimeter if you’re unfamiliar with how to prevent short-circuiting.

How to troubleshoot the F33 error code

Follow these steps to troubleshoot & fix the F33 error on your GE dishwasher.

1. Unplug the dishwasher from the outlet.
2. Find the door latch assembly, which is located on top of the dishwasher tub.
3. Make sure that there are no obstructions that could prevent the door from closing properly. Clear any debris as needed.
4. Check the latch assembly to make sure it’s functioning correctly.
5. Look over the wiring. If it’s damaged (frays, burn spots, etc.), it’ll need to be replaced.
6. Find the main control board of the dishwasher, which is at the bottom, behind the kickplate. To access it, you’ll need to remove the kickplate.
7. Find the connector labeled J711 on the main control board. Disconnect this connector to isolate the door switch circuit for testing.
8. Set a multimeter to continuity.
9. Use the multimeter probes to check the continuity from pin 3 (tan and red) to pin 4 (violet and yellow), and from pin 3 (tan and red) to pin 5 (white and silver). Both connections should be open (no continuity; no beep from the meter) when the door is open and closed (continuity; a beep from the meter) when the door is closed. If you don’t get these results while testing, that means there’s a problem with the door switch or its wiring.

If the door switch tests OK at the control board, then the control board will need to be replaced.
