KitchenAid Dishwasher Error Code F1E2 — Control Board Memory Corruption
What this means
The F1E2 error code on KitchenAid dishwashers indicates the control board's memory chip (MCU — Microcontroller Unit) has corrupted data. This can happen after a power surge, brownout, or electrical interference. The dishwasher may behave erratically, fail to complete cycles, or not start at all.
Alternate codes: 1-2
Step-by-step fix
3 stepsReset the dishwasher
Unplug the dishwasher for 5 minutes, then restore power. A power cycle can sometimes allow the control board to reinitialize its memory.
If the code clears and doesn't return, the corruption was temporary.
Check for repeated occurrence
If the code returns after the reset, the memory chip is permanently corrupted and the control board needs to be replaced.
Replace the control board
The control board must be replaced. Photograph all connections, disconnect, swap the board, and reconnect.
Consider adding a surge protector to the dishwasher's circuit to prevent future power-related damage.
