Error Code: Washer Difficulty: Hard
Problem: Motor control unit internal failure or communication timeout
How to Fix Washer Error
- Power cycle washer by unplugging for 5 minutes.
- Remove rear access panel to expose motor control unit (MCU).
- Inspect all connectors at MCU for corrosion, bent pins, or loose seating – reseat firmly.
- Check 3-wire serial communication harness between MCU and main control board (CCU) for damage.
- Verify 120V AC power reaches MCU during operation (test at L1/L2 terminals).
- Measure DC voltage at MCU output to motor (should be 30-150V DC variable depending on speed).
- If power present but no motor operation, replace MCU assembly W
- After replacement, run diagnostic mode verifying communication handshake between CCU and MCU.
- If F10 returns after MCU replacement, suspect main control board failure requiring CCU replacement.
