How to Fix / Troubleshooting
Safety first: Unplug the unit before removing any control panel covers.
- Step 1 – Power reset: Unplug for 5–10 minutes, then plug back in and test. Sometimes static or minor glitches can clear.
- Step 2 – Drying period: If the panel was exposed to steam or spills, leave the unit unplugged in a warm, dry room for 24 hours to allow moisture to evaporate.
- Step 3 – Clean surface: Wipe the control panel with a slightly damp cloth and then dry thoroughly. Do not use excessive liquid or spray cleaners directly on the panel.
- Step 4 – Check ribbon cable (advanced): Remove the control panel cover and verify that the flat ribbon cable from the touch panel to the control board is fully inserted and not damaged.
- Step 5 – Replacement: If certain buttons never respond and E09 persists, the touch panel or UI board likely needs replacement.
