Possible Causes

Element insulation breakdown to chassis, Damaged wiring harness touching metal frame, Moisture inside element or terminal block, Faulty mains filter (EMI suppressor) leaking to earth

How to Fix / Troubleshooting

Safety: This fault can involve dangerous earth leakage. Disconnect power and do not repeatedly reset a tripping breaker.

Steps:

  • 1. Visual inspection: Remove rear panel and inspect all heating elements (bake, grill, fan) and their wiring for signs of arcing, burn marks, or insulation damage.
  • 2. Insulation test (if equipment available): Using an insulation tester (megger), test between each element terminal and chassis. Any low resistance indicates leakage; replace the affected element.
  • 3. Check mains filter: Locate the mains interference filter where the power cord enters. Look for bulging, cracking, or burning. Replace if damaged.
  • 4. Dry moisture: If the cooker has been steam-cleaned or exposed to water, allow it to dry thoroughly (doors open, 24–48 hours) before retesting.
  • 5. Professional help: If you cannot identify the leaking component, contact a qualified technician; do not continue using the appliance.
