Possible Causes
Shorted heating element to earth, damaged wiring insulation, moisture inside oven or hob, faulty terminal block connection
How to Fix / Troubleshooting
Safety first: Do not repeatedly reset the breaker without finding the cause. Isolate the cooker from the mains.
Steps to check:
- Identify which function: Note whether the trip occurs when using a specific oven, grill, or hob zone.
- Inspect terminal block: Check the main connection block for signs of overheating or loose wires. Tighten or replace as needed.
- Check elements: Disconnect suspected elements one at a time and test insulation resistance to earth (qualified persons with appropriate meter). Replace any element with low insulation resistance.
- Look for moisture: If the issue started after heavy cleaning or a spill, allow the appliance to dry thoroughly for 24 hours.
- If fault persists: A professional electrician or appliance engineer should perform further insulation and continuity tests.
