Error Code: Washer Difficulty: Hard
Problem: Communication error between ACU (analog control unit) and CCU (central control unit)
How to Fix Washer Error
- Unplug washer for 5 minutes to reset communication bus.
- Remove top panel to access main control board (CCU) connections.
- Locate multi-wire harness connecting CCU to ACU (typically 8-12 wires in gray connector).
- Disconnect and reconnect harness at both ends, inspecting for bent pins or corrosion.
- Check harness routing for pinch points between tub support and cabinet.
- Verify continuity on all pins between CCU and ACU connectors (no opens or shorts to ground).
- Inspect both boards for moisture damage or burnt components near communication ports.
- If harness tests good but error persists, replace ACU board first (less expensive component).
- If F6E1 returns after ACU replacement, replace main control board (CCU) W
- After repair, enter diagnostic mode and verify all sensor readings display correctly on interface.
