This thread was marked as solved. Here's a summary of the problem and the fix, generated from the discussion below.
Washing machine trips the house breaker when switched on
- The problem
- The washing machine trips the main house circuit breaker every time it is turned on. The machine's fuse was reported as fine.
- Likely cause
- The strongest diagnosis in the discussion is a shorted heater. A secondary possibility mentioned was a motor fault if isolating the heater circuit did not stop the breaker tripping.
- What fixed it
- The advised approach was to isolate components one at a time with the appliance unplugged to identify which circuit is causing the trip. The main suggestion was that if isolating the pressure-switch/heater feed stopped the tripping, the heater was faulty. No completed repair or replacement was confirmed in the thread.
- Checks to try
- Machine fuse reported as fine
- Fault occurs every time the machine is switched on
- Suggested isolating the purple wire with black stripes from the pressure switch circuit to see if tripping stops
- Suggested disconnecting the motor connector if the first isolation test did not stop the tripping
- Parts or tools mentioned
- Insulating tape
- Heater
- Motor
Safety: Further diagnosis should be carried out by a suitably qualified appliance engineer.

When fault finding you don't have to always do a resistance test, you can use the old fashioned fault finding method by taking components out of circuit.
On your machine, unplug it and remove the lid. Behind the front panel there will be a small round pressure switch with several wires attached and a plastic tube. Remove the purple wire with black stripes, tape up the end of it with insulating tape, try the machine.
If it works, it's your heater at fault. If it blows, unplug, remove the motor connector, switch on. If it doesn't blow it's the motor. It's as simple as this, just take things out of circuit until you stop blowing the circuit breaker and you can find the component at fault. The purple wire will likely fix it, Heaters in these normally short when they go.
