Buttons on the KitchenAid dishwasher control panel do not respond correctly; some keys seem stuck or always "on"; error may appear as F2E1 or keypad error.

Safety First: Turn off power at the breaker before removing the door panel.

Try a soft reset:

• Turn off power for 2–3 minutes, then restore power and test the panel.
• If the same keys are still unresponsive or the code returns, proceed with inspection.

Inspect the user interface (UI):

• Open the door and remove the screws around the inner door panel to access the UI board and keypad.
• Check the ribbon cable between the UI and main control for corrosion, kinks, or loose connections. Reseat the cable firmly.
• Look for signs of moisture or detergent residue on the UI board. If present, gently clean with a dry cloth and allow to air dry completely.
• If keys feel physically stuck or the membrane is bubbled or cracked, the UI assembly should be replaced.

Replacement:

• Order the correct KitchenAid dishwasher user interface/control panel by model number.
• Transfer any brackets or trim from the old panel to the new one, reconnect the ribbon cable, and reassemble the door.
