How to Fix / Troubleshooting

Safety: Turn off power at the breaker before disassembling the door.

Clean the panel surface: Wipe the control panel with a slightly damp cloth and mild detergent to remove grease or residue around buttons. Do not soak the panel.
Power cycle: After cleaning, turn power off for 5 minutes, then restore and test. Sometimes the code clears if the key is no longer stuck.
Inspect from inside: Remove the inner door panel to access the back of the touchpad. Check for moisture, corrosion, or physical damage to the keypad membrane and ribbon cable.
Dry and reseat: If moisture is present, dry thoroughly. Reseat the ribbon cable into the main control, ensuring it is fully inserted and locked.
Replace touchpad/UI: If F2E1 persists and a specific button feels stuck or does not click, replace the touchpad or full UI assembly as designed for your JennAir model.

Tip: Avoid pressing the same area excessively hard; this can permanently deform the membrane.

Dishwasher beeps and shows F2E1; some or all buttons do not respond, or panel seems stuck on one setting.
