Unit trips the household circuit breaker or RCD when starting.

Safety first: Do not repeatedly reset a breaker that trips. Unplug the fryer and leave it unplugged until inspected.

• Visual inspection: Remove the cover and look for obvious shorts: burnt wires, melted insulation, or metal contacting live parts.
• Heater test: Disconnect heater leads and test resistance to chassis ground. Any continuity indicates a shorted element that must be replaced.
• Check for moisture: If the unit was recently washed or exposed to heavy steam, allow it to dry thoroughly for 24–48 hours before retesting.
• Professional service: Because this involves safety‑critical mains insulation, repairs should be carried out by a qualified technician.
