How to Fix / Troubleshooting
Safety first: Do not repeatedly reset a breaker that trips immediately. Disconnect the appliance and have the circuit inspected.
- Identify when it trips: Note whether the trip occurs when a specific function (e.g., grill, one burner, or induction zone) is used. This helps locate the faulty circuit.
- Inspect elements and wiring: With power off, remove rear and bottom panels to inspect elements and wiring for signs of arcing, burns, or insulation damage.
- Check terminal block: Ensure the mains connection block is tight and not burnt.
- Dry moisture: If water has entered the appliance (e.g., from cleaning), allow it to dry thoroughly for 24–48 hours before retesting.
- Replace faulty parts: Replace any element or wiring harness that shows signs of shorting. If the fault cannot be easily located, contact a qualified electrician or appliance technician.
