Oven trips the circuit breaker or RCD as soon as it is turned on or when a specific function is selected.

Safety first: Do not repeatedly reset a tripping breaker. Disconnect the oven and ensure it remains off until the fault is located.

• Identify the mode causing trip: Note whether the breaker trips when selecting grill, bottom heat, fan, or any mode. This helps isolate the faulty circuit.
• Insulation test of elements: With power disconnected, remove at least one wire from each heating element and measure resistance between each element terminal and the oven chassis. Any low resistance (near 0 Ω) indicates a shorted element that must be replaced.
• Inspect wiring harness: Look for pinched or melted wires where they pass through metal panels. Repair or replace damaged sections and secure with proper clips.
• Check interference filter: The mains filter module can fail and cause RCD trips. Inspect for burns or cracks and replace if suspect.
• Dry moisture: If the oven was recently cleaned with large amounts of water or steam, allow it to dry thoroughly (door open, power off) for 24 hours and retest.
