What this code means
IMC Communication Fault - Inverter failed to receive a valid communication for 10 seconds.
First step from the service manual
Reset control boards by unplugging the washer for 30 seconds. Check the wiring between the IMC and UI boards.
Next steps: diagnose the root cause
1
Verify the error code is active
Power cycle the unit and see if the code returns. If it does, the fault is persistent and requires diagnosis.
2
