What causes the F112 fault?

On GE dishwashers, the F112 fault code signifies that one of the push buttons on the user interface control is stuck or malfunctioning.

Under normal operation, a button’s electrical circuit is only closed momentarily when pressed. If a button remains closed longer than expected, the control interprets this as a stuck button and displays an F112 error. For example, if food or debris worked under a button keeping it pressed down, it would trigger this fault code. 

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 attempting any maintenance or replacement work. This keeps you safe by preventing any risk of injury from electric shock.
• Wear insulated work gloves to protect your hands from sharp metal parts, pinching hazards and debris.
• Take your time and don’t rush while working to prevent accidents and personal injuries.
• Work in a well-lit area so you can clearly see and access the interior parts.
• Clear your workspace of clutter and other obstacles. Keep children and pets away from the work area.
• Never work on internal parts with bare wet hands. Make sure the work area is completely dry.
• Check your user manual to see if there are specific installation or safety instructions for your part or appliance. 
• Be gentle when handling or removing parts. Excessive force might damage the appliance or cause injury.
• Wear safety glasses when working with chemicals, dust or cleaning large debris to prevent injury. 
• If the appliance has recently been used, give it plenty of time for any heating parts to cool down before working on it. 
• Take pictures or make a note of wiring terminals or other connections before disconnecting to prevent any problems with reassembly.
• 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.
• Turn off the water supply at the outlet before beginning repairs to any appliance parts that hold water. Have towels ready for any residual water in the system when removing parts.

Troubleshooting steps

Step 1: Perform a power cycle

1. Unplug the dishwasher from the power source and wait for at least 60 seconds.
2. Plug the dishwasher back in or restore power to the circuit.

3. Observe the dishwasher’s behavior and check if the error was temporary and has been cleared.

Step 2: Check the buttons

1. Inspect the control panel buttons to ensure they are functioning properly. Press each button firmly and check that the corresponding action is triggered on the dishwasher.
2. Gently clean the buttons using a soft, damp cloth to remove any debris or buildup that may be interfering with their operation.

Step 3: Inspect the console and light pipe

1. Examine the dishwasher’s console, where the control panel is located, for any signs of damage or discoloration.
2. Check the light pipe, which is responsible for transmitting the indicator lights from the control board to the console. Ensure the light pipe is properly seated and not cracked or broken.
3. If the console or light pipe appears damaged, they may need to be replaced.

Step 4: Test the user interface (UI)

1. If the buttons and console appear to be in good condition, the issue will be with the user interface.
2. Use a multimeter to check for continuity between the UI connectors and the control board. Refer to the wiring diagram in your owner’s manual to identify the correct test points.
3. If the UI is not functioning properly, it will need to be replaced.

Step 5: Replace the User Interface (UI)

1. Purchase a replacement UI assembly that is compatible with your specific GE dishwasher model.
2. Install the new UI assembly by reconnecting the wires and securing it in place.
3. Restore power to the dishwasher and test the new UI to ensure it is functioning correctly.
