Cooktop trips the circuit breaker or RCD when a zone is turned on.

Safety: Leave the breaker off until the fault is identified. Risk of electric shock and fire.

• Isolate zone: If possible, identify which zone causes the trip by turning them on one at a time (with caution and only if the breaker allows brief operation).
• Inspect internals: Remove the hob and bottom cover. Look for obvious signs of burning, melted insulation, or arcing near the affected zone.
• Test components: Use a multimeter to check resistance from each element or coil terminal to earth. Any low resistance indicates leakage and the part must be replaced.
• Replace faulty part: Install a new Ariston element or induction coil and repair any damaged wiring with high-temperature cable.
• Professional help: If you are not experienced with electrical testing, have a qualified technician perform these checks.
