Samsung Dishwasher Error Code CE — Communication Error
What this means
The CE error code indicates a communication failure between the main control board and the sub-board or display board. This can result from a loose wire harness, a power surge, or a failed control board component. The dishwasher will not operate until communication is restored.
Step-by-step fix
3 stepsPower cycle the dishwasher
Turn off the circuit breaker for 10 minutes. This allows the control boards to fully discharge and reset. Turn the power back on and start a cycle.
Power surges from thunderstorms or grid fluctuations commonly cause temporary communication errors.
Check wire harness connections
Turn off the breaker. Remove the inner door panel to access the control boards. Locate the wire harness connectors between the main board and the display/interface board. Disconnect and firmly reseat each connector.
Look for corrosion, burnt pins, or moisture on the connectors.
Inspect the control boards
Visually inspect both boards for burned components, discoloration, swollen capacitors, or corrosion. Any visible damage indicates the board needs replacement.
Take photos of all connections before disconnecting anything for reference during reassembly.
When to call a professional
Control board diagnosis and replacement should be handled by a qualified technician who can determine which board has failed and order the correct replacement.
