How to Fix / Troubleshooting
Safety first: Isolate the hob from mains before accessing any internal wiring. This fault involves live components.
- Power cycle: Turn off the hob at the breaker for 5–10 minutes, then restore power. Temporary glitches can clear with a full reset.
- Check for moisture: If there has been a major spill, moisture may have reached the electronics. Allow the hob to dry for several hours with power disconnected.
- Professional inspection: A technician should remove the hob, check the ribbon cable and connectors between the touch control and power module, and reseat or replace as needed.
Do not continue using the hob if E6 persists; internal arcing or further damage may occur.
