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

Safety first: Do not repeatedly reset a breaker that trips. Disconnect the cooktop from mains and do not use it until inspected.

• Step 1 – Check for moisture: If the issue started after a spill or cleaning, allow the cooktop to dry for 24 hours with good ventilation.
• Step 2 – Visual inspection (technician): Open the underside and inspect all wiring for damage, especially where it passes through metal openings. Repair or replace damaged wires and add grommets if needed.
• Step 3 – Insulation tests: Use a megohmmeter (technician) to test insulation resistance between live parts and earth. Identify any element or module with low insulation and replace it.
• Step 4 – Replace faulty module/element: If a specific zone causes tripping, replace its power module or heating element as indicated by tests.

RCD trips indicate potential shock hazards; only qualified personnel should perform detailed diagnostics.
