Dryer powers on but immediately trips the household circuit breaker or RCD when a cycle is started.

Safety first: Turn off the breaker and unplug the dryer. Do not repeatedly reset a tripping breaker.

• Inspect power cord and plug: Look for burn marks, cuts, or loose terminals. Replace if damaged.
• Check heater for ground fault: Disconnect heater wires and test resistance between each terminal and the metal housing. Any continuity indicates a shorted element that must be replaced.
• Inspect wiring: Remove rear and top panels and look for pinched or melted wires touching the cabinet. Repair or replace damaged sections.
• Check for moisture: If the dryer has been exposed to leaks or high humidity, allow it to dry thoroughly before retesting.
• If the fault persists, a technician should perform insulation resistance tests and inspect the main PCB.
