Kenmore Dishwasher Error Code CE — Communication Error Between Boards
What this means
The CE error code on Kenmore dishwashers indicates a communication failure between the main control board (at the bottom of the dishwasher) and the user interface board (behind the control panel on the door). These two boards communicate via a ribbon cable or wire harness. The error can be caused by a loose connection, a damaged cable, moisture in the door, or a failed board.
Step-by-step fix
4 stepsReset the dishwasher
Turn off the dishwasher at the circuit breaker for 5 minutes, then turn it back on. Power surges or electrical noise can temporarily disrupt board communication, and a reset may clear the error.
If the error appeared right after a power outage or storm, a simple reset is especially likely to fix it.
Check the door wire harness
Unplug the dishwasher. Open the door and remove the inner door panel screws. Carefully separate the inner panel to access the wiring that runs through the door hinge area. Check the wire harness for pinched, broken, or corroded wires — the constant opening and closing of the door can damage these wires over time.
Flex the door harness while visually inspecting for wire breaks — damage often occurs right at the hinge bend point.
Reseat the board connectors
Locate the user interface board at the top of the door and the main control board behind the lower kick plate. Disconnect and firmly reseat all wire harness connectors on both boards. Look for corrosion, burned pins, or loose-fitting connectors.
Use electrical contact cleaner spray on the connectors to remove any corrosion or oxidation.
Test the communication cable
If reseating doesn't work, use a multimeter to test continuity through each wire in the communication harness between the two boards. A broken wire will show an open circuit.
If you find a broken wire, you can splice and solder a repair rather than replacing the entire harness — just make sure to insulate the repair with heat-shrink tubing.
When to call a professional
If the wiring tests good but the error persists, one of the two control boards has failed. Diagnosing which board is at fault and replacing it should be done by a qualified appliance technician.
