Possible Causes
Loose communication harness, Oxidized connector pins, Faulty user interface PCB, Defective power module microcontroller
How to Fix / Troubleshooting
Safety first: Disconnect the appliance from mains power before accessing internal components.
- Reset: Turn off power for at least 10 minutes, then restore. Sometimes transient communication errors clear after a reset.
- Access electronics: Remove the cooktop from the worktop and open the underside cover to expose the user interface board and power module.
- Check harness: Locate the low-voltage communication cable between the boards. Unplug and replug the connectors several times to clean contacts. Inspect for bent pins or corrosion.
- Inspect for moisture: Look for signs of liquid ingress around the control area. Dry thoroughly and consider replacing affected boards if corrosion is present.
- Board substitution: If wiring is intact and E7 persists, either the user interface PCB or the power module is faulty. Replacement and testing should be carried out by a qualified technician with access to Glem Gas parts.
