Washer-dryer trips the household circuit breaker or RCD when starting or during a cycle.

Safety first: Do not repeatedly reset a breaker that trips immediately; this indicates a potentially dangerous fault. Unplug the appliance before inspection.

• Visual inspection: Remove the rear panel and top cover. Look for signs of water leaks, burn marks, or melted insulation around the heater, motor, and wiring.
• Check mains cable: Inspect the power cord for cuts or crushing, especially where it enters the cabinet.
• Heater check: Disconnect the heater wires and try running a cold cycle. If the breaker no longer trips, the heater is likely shorted and should be replaced with a Bush-compatible heater element.
• Address leaks: If water is present near electrical parts, locate and repair the leak (door seal, hoses, pump) before further use.
• Professional testing: Persistent tripping without obvious cause should be investigated by a qualified electrician or appliance technician.
