How to Fix / Troubleshooting
Safety first: Disconnect the appliance from mains before removing the control panel.
- Dry the panel: If condensation or spills have reached the control area, leave the unit unplugged with the door slightly open for several hours to dry. Do not use direct heat.
- Inspect ribbon cable: Remove the front control fascia to access the touch panel and its ribbon cable. Ensure the cable is fully inserted and not damaged or corroded.
- Check for cracks: Examine the touch panel for physical damage or delamination. Replace the user interface assembly if damaged.
- Board input test: If the panel appears intact, the fault may be on the main control board. Inspect for burnt components near the keypad connector. Replace the board if necessary.
- Reassemble and test: Refit the panel, restore power, and test all buttons or touch zones for proper response.
