How to Fix / Troubleshooting
Safety first: Unplug the washer before accessing electronics.
- Hard reset: Disconnect power for at least 15 minutes, then plug back in and attempt to enter a basic cycle.
- Check interface cable: Remove the control console and reseat the ribbon cable between the display board and main PCB.
- Environment: Ensure the washer is not exposed to excessive moisture at the control panel, which can cause intermittent shorts.
- Board replacement: If E90 persists, the main PCB may need to be replaced and configured according to Comfee service procedures. This is best done by an authorized technician.
