Possible Causes
How to Fix / Troubleshooting
Safety first: This is a high‑voltage, high‑current fault. Do not continue using the hob. Switch off at the mains and do not attempt internal repairs unless you are qualified.
- Disconnect power: Turn off the cooker/hob at the main isolator or breaker immediately.
- Inspect from above: Once cool, check for obvious liquid spills that may have run through gaps in the glass. Clean the surface thoroughly.
- Do not bypass safety: Do not attempt to repeatedly reset and use the zone; this can damage the power electronics further.
A professional technician must remove the hob, inspect the induction coil, wiring, and power module, and replace any shorted components.
