How to Fix 9C7 Error

UNPLUG WASHER IMMEDIATELY – safety hazard present. Do not operate until repaired.
Visually inspect all wiring harnesses for melted insulation or chafing against sharp edges (pay attention to motor and heater connections).
Disconnect all loads (heater, pump, motor) at PCB and power up briefly – if error clears, reconnect loads one-by-one to isolate fault.
Test each load for shorts to ground with megohmmeter (>1MΩ required; <100kΩ indicates fault).
Inspect PCB for burnt traces near power relays or inverter section (look for carbon tracking).
Replace main PCB DC92-01543A and any damaged wiring harnesses.
NEVER operate washer with this error until root cause identified – fire risk exists from uncontrolled current flow.
