How to Fix / Troubleshooting
Safety first: Disconnect the hob from mains before any service work.
- Power cycle: Turn off the hob at the breaker for 10 minutes and then restore power. Sometimes configuration errors clear after a full reset.
- Check for recent work: If a control board was recently replaced, it may be the wrong part number or not programmed for your specific Grundig model.
- Service intervention: A Grundig‑authorized technician may be able to reprogram or must replace the control PCB.
Do not attempt to flash firmware or modify electronics without proper tools and documentation.
