How to Fix / Troubleshooting
Safety first: Unplug the machine before working on the control panel.
Cleaning:
- Remove the front panel and carefully clean around the buttons with a dry cloth.
- Check for sticky residue from spills and clean with a lightly dampened cloth (no excessive liquid).
Component check (advanced):
- Inspect the keypad PCB for corrosion or cracks.
- Test individual tactile switches with a multimeter; replace any that do not close reliably.
- Ensure the ribbon cable to the main board is firmly seated.
In many cases, replacing the entire control panel assembly is the most efficient repair.
