Whirlpool Dishwasher Error Code Stuck Key

The Stuck Key error means the control board has detected that one or more buttons on the control panel are registering as continuously pressed. The dishwasher suspends all operation and flashes the LED next to the affected button to identify which key is causing the issue. If the problem button has no LED, or if multiple keys are affected, the lock-out LED will flash instead. The machine will not operate until the stuck key condition is resolved.

A reset may temporarily clear the error display, but the code will return if the underlying physical cause is not corrected. The control detects the stuck key condition actively, so as long as a key contact remains closed, the fault will reappear after power is restored. Resolving the root cause, whether debris, a damaged touchpad, or a faulty component, is necessary for a permanent fix.

If the cause is simply debris or residue, there is no parts cost and only your time is required for cleaning. Replacing the touchpad or membrane switch assembly typically costs between $50 and $150 for the part, depending on the model, plus labor if a technician performs the work. Control board replacement, if needed, is generally more expensive, ranging from $100 to $300 or more for the component alone.

Start by observing which LED is flashing on the control panel, as this identifies the stuck key. Inspect that button for debris, residue, or physical damage and clean the area carefully. If cleaning does not resolve the issue, the touchpad or membrane switch assembly may need to be replaced. In cases where the lock-out LED is flashing, check all keys and the ribbon cable connection between the touchpad and control board.

The dishwasher suspends operation automatically when this error is active, so it will not run a wash cycle until the condition is corrected. There is no immediate safety hazard from the error itself, but the machine cannot be used until the stuck key is identified and the fault is resolved. Do not attempt to force a cycle by repeatedly pressing buttons, as this could complicate diagnosis or further stress the touchpad.
