Hoover oven trips the circuit breaker or RCD when turned on or when a specific function is selected.

Safety first: Do not repeatedly reset a breaker that trips immediately; isolate the oven and investigate. Work only with power off.

• Identify offending function:
  • Note which selector position causes the trip (fan oven, grill, etc.).
• Inspect relevant element and wiring:
  • Access the element associated with that function.
  • Look for visible damage or wiring touching metal parts.
  • Test element resistance to earth with a multimeter; any continuity to earth indicates leakage.
  • Replace the element if leaking or shorted.
• Check mains terminal block and filter:
  • Inspect for moisture, carbon tracking, or melted plastic.
  • Replace the mains filter or terminal block if damaged.
• Drying:
  • If the oven has been exposed to water or steam, leave it disconnected with the door open for 24–48 hours to dry, then retest.
