Frigidaire Dishwasher Error Code CE — Communication Error
What this means
Error code CE indicates a communication failure between the main control board and the user interface (keypad/display) board. This can be caused by a loose ribbon cable, a faulty interface board, or a failed main control board. The dishwasher will not respond to button presses.
Step-by-step fix
4 stepsPower cycle the dishwasher
Turn off the circuit breaker for 5 minutes, then restore power. A temporary communication glitch may clear with a reset.
Power fluctuations and surges are a common cause of temporary communication errors.
Check the ribbon cable
Remove the outer door panel to access the electronics. Inspect the ribbon cable connecting the keypad to the control board for damage, kinks, or loose connections.
The ribbon cable can become damaged when the door panel is removed and reinstalled during other repairs.
Reseat all connections
Disconnect and firmly reconnect the ribbon cable at both ends. Also reseat the main wiring harness connections on the control board.
Moisture from steam can sometimes corrode connector pins — look for green or white corrosion.
Replace the user interface or control board
If reseating connections doesn't work, the interface board or main control board needs replacement. Try the interface board first as it's less expensive.
Note your dishwasher model number — interface boards are model-specific.
When to call a professional
If you've replaced the interface board and the error persists, the main control board is likely the problem.
