How to Fix / Troubleshooting
Safety: Control panel work involves exposure to mains voltage; internal access should be left to professionals.
What you can do:
- Dry the panel: If the panel has been exposed to steam or cleaning fluid, unplug the unit and let it dry for several hours.
- Clean gently: Wipe the control panel with a slightly damp cloth, then dry thoroughly. Do not spray cleaner directly onto the panel.
- Reset: After drying, plug in and test the buttons.
If H19 remains or some keys do not respond: The membrane keypad or control PCB likely needs replacement by a technician.
