Possible Causes
Failed main control board, corrupted firmware, power surge damage, internal CCU communication fault
How to Fix / Troubleshooting
Safety first: Unplug the washer.
Attempt reset:
- Leave the washer unplugged for at least 10 minutes to allow capacitors to discharge.
- Plug back in and attempt to enter diagnostic mode (refer to your user/tech manual). If F70 returns immediately, the CCU is likely defective.
Inspect board:
- Remove the console panel and visually inspect the CCU for burnt components or corrosion.
In most cases, F70 requires replacement of the main control board with the correct Crosley part. This is an advanced repair; consider professional service.
