Quick summary
A tripping breaker is a safety signal—don't keep resetting it. Causes include the heater, motor, pump, a leak or household wiring. Diagnosis requires insulation testing.
When the breaker or residual-current device trips as soon as the washer starts or at a specific stage, abnormal current is flowing. The timing is a strong clue to the source.
Unplug the appliance, close the water tap if there's a leak, and never open covers that need tools or expose wiring or circuits.
Possible causes
Heater insulation failure
Typically trips when heating begins on warm programs.
Water reaching electrical parts
From an internal leak or heavy humidity.
Motor or pump
A damaged winding or connection can trip during spinning or draining.
Socket or wiring problem
Poor earthing, a damaged socket or an oversensitive breaker.
Safe checks you can do
- Note when it trips: on plugging in? when heating? when draining?
- Try a different direct wall socket, no extension lead.
- Make sure the floor around the washer is dry and the plug is undamaged.
When to stop checking immediately
- Don't reset the breaker more than once if it trips immediately.
- If you feel a tingle from the appliance, switch off the main breaker.

When do you need a technician?
The technician measures insulation on the heater, motor, pump and internal wiring, inspects for leak traces and pinpoints the cause.
FAQ
It only trips on hot programs—why?
A common pattern with heater insulation failure, but it must be confirmed by measurement.
Is it the washer or my home wiring?
Try another socket; if it still trips, the washer is the likely cause.
