GE Dishwasher Error Code F155

F155 indicates that the dishwasher's control system has detected a stuck tactile key on the User Interface panel. One or more buttons is registering as continuously pressed rather than returning to its resting state. The cause can be physical, such as debris or plastic flash blocking the button, or electrical, such as a fault on the UI board itself.

A reset may temporarily clear the code, but if the underlying cause is not addressed, the fault will return. If a button is physically stuck or the UI board has failed, the dishwasher will detect the condition again on the next power cycle. Address the root cause before relying on a reset as a solution.

If the fix is simply cleaning debris or removing plastic flash from a button, there is no parts cost involved. If the User Interface board needs to be replaced, parts and labor costs typically range from $150 to $350 depending on the specific model and service rates in your area. Diagnosing the physical buttons first is always recommended before committing to a board replacement.

Yes, in many cases. Start by pressing each button on the control panel and confirming that every one produces a clear click and springs back. Look closely around the edges of each key for debris, food residue, or thin plastic flash that could be blocking button travel. Cleaning around the buttons or carefully removing any plastic obstruction may clear the fault without any parts replacement.

The dishwasher will typically stop normal operation when this code is active, which limits the risk of unintended behavior. However, it is best not to attempt to force the appliance to run while a control fault is present. Address the stuck key issue before resuming use to avoid any further complications with the control board.
