How to Fix / Troubleshooting
Safety first: Unplug the dryer before accessing electronics.
- Power cycle: Disconnect power for 10 minutes, then reconnect and test.
- Inspect communication cable: Remove the top panel and locate the ribbon or harness between the UI and main board. Ensure it is fully seated at both ends and not damaged.
- Check for pin damage: Look for bent pins in the connectors. Carefully straighten if necessary.
- Isolate interference: Ensure no high-power devices share the same outlet or circuit that could introduce electrical noise.
- Board substitution: If cabling is intact, replace the user interface board first. If E18 persists, replace the main control board.
