Oven trips household circuit breaker or RCD when heating starts, error may be logged

Safety first: Do not repeatedly reset a tripping breaker. Disconnect the oven and investigate before further use.

• Isolate modes: Try different heating modes (conventional, grill, fan) one at a time to identify which element causes the trip. If any mode immediately trips, suspect that element.
• Insulation test: With power disconnected, remove the rear panel and disconnect each heating element. Use a megohmmeter (insulation tester) between each element terminal and earth. Low insulation resistance indicates a faulty element that must be replaced.
• Inspect wiring: Look for pinched or melted wires touching the metal chassis. Repair or replace damaged sections.
• Check mains filter: Inspect the EMI filter module near the mains entry for burn marks or cracks. Replace if damaged.
• Drying: If the issue started after heavy cleaning, allow the oven to dry for 24 hours with the door open, then retest. Persistent tripping requires component replacement.
