How to Fix / Troubleshooting
Safety first: Turn off power at the breaker before removing the control panel.
Step-by-step checks:
- Dry the panel: Wipe the control panel with a dry cloth. If steam has been escaping, allow the unit to dry for several hours with the door open.
- Power reset: Cycle the breaker off for 5 minutes, then back on to clear temporary faults.
- Door panel removal: Remove inner door screws and carefully separate the panels to access the user interface board and ribbon cable.
- Inspect cable: Check the ribbon cable for kinks, corrosion, or loose connections at both ends.
- Replace UI board: If specific buttons never respond and E18 persists, the user interface board may need replacement.
Warning: Avoid using excessive water or cleaners on the control panel; this can cause recurring failures.
