Unit trips the household circuit breaker or RCD when switched on.

Safety first: Do not repeatedly reset the breaker. Unplug the unit immediately. Water and electricity are dangerous together.

• 1. Inspect for moisture: Check around the base and inside the housing (if competent to open) for signs of water leaks. Dry thoroughly and fix any leaks before further testing.
• 2. Examine power cord: Look for cuts, crushed sections, or exposed wires. Replace the cord if damaged.
• 3. Motor test: With the unit unplugged and opened, disconnect the motor and test insulation resistance if you have appropriate equipment. A shorted motor must be replaced.
• 4. Mains filter board: Inspect for burnt components or cracked casing. Replace if damaged.
• 5. Professional service: If you are not experienced with mains electrical testing, have a qualified technician diagnose and repair the fault.
