GE Dishwasher Error Code F112

F112 indicates that the dishwasher's user interface control has detected a key that appears to be continuously stuck in the pressed position. The control board monitors button input signals, and when one remains active without interruption, it flags the F112 fault. This can be caused by a stuck button, debris or moisture under the panel, a displaced light pipe, or a faulty UI board.

A reset may temporarily clear the F112 code, but if the underlying cause is not corrected, the error will return. If a button is physically stuck or the light pipe is pressing against a contact, the fault will reappear as soon as the control runs its self-check again. A reset is useful for ruling out a one-time software glitch, but a persistent F112 requires physical inspection and likely component repair or replacement.

If only cleaning or minor adjustment is needed, the repair may cost little to nothing. If the UI control board requires replacement, parts typically range from $50 to $200 depending on the specific model, with professional labor adding $100 to $250 on top of parts. Replacing the membrane keypad or light pipe assembly is generally less expensive than a full UI board replacement.

In many cases, yes. Start by inspecting each button on the control panel for sticking, debris, or physical damage. Check the light pipe assembly for cracks or displacement. If a button is physically stuck, carefully cleaning around it may resolve the issue. If the panel and buttons appear fine, the UI control board will likely need to be replaced, which is a more involved repair but achievable for a confident DIYer.

It is generally not recommended to continue using the dishwasher while F112 is active. A stuck button input can cause the control system to behave unpredictably, potentially starting unintended cycles or preventing the unit from completing a cycle correctly. Address the fault before resuming regular use to avoid potential water or electrical issues.
