Possible Causes
Stuck or shorted keypad button, Moisture ingress into control fascia, Loose ribbon cable between UI and main board, Defective user interface PCB
How to Fix / Troubleshooting
Safety first: Disconnect power before removing the control panel.
- Check for stuck buttons: Press each button individually and ensure it returns freely. Clean around buttons with a slightly damp cloth (power off) to remove detergent or lint buildup.
- Dry moisture: If the panel has been exposed to steam or liquid, allow it to dry completely for several hours with the door open and power disconnected.
- Inspect ribbon cable: Remove the control fascia and locate the flat ribbon cable to the main board. Reseat both ends carefully, ensuring no kinks or damage.
- Visual inspection: Look for corrosion or burn marks on the user interface PCB. If present, replacement is recommended.
- Test operation: Reassemble and power on. If F7 recurs and specific keys do not respond, replace the user interface module.
