How to fix it
- Unplug the washer for 5 minutes to attempt a soft reset.
- If the code returns, unplug again and reseat every connector on the main control board.
- Inspect the board visually for burnt traces, swollen capacitors, or browning.
- Replace the main control board (CCU) — there's no field-repair short of a specialty board-rebuild service.
- Plug a surge protector into the wall before reinstalling to prevent recurrence.
