Trips Fuse Board Rcd When Door Is Closed?
Hi, we've had the machine from new and it's never let us down until recently. It powers up ok but when the door is closed, the main 100mA RCD/ earth leakage circuit breaker at the fuseboard trips out. Could the door lock switch be faulty? Is the machine worth fixing and keeping as a spare or is this one scrap metal too???
Cheers,
Ian

AI-generated from this discussion
This thread was marked as solved. Here's a summary of the problem and the fix, generated from the discussion below.
Washing machine trips RCD when the door is closed
- The problem
- The washing machine powers up, but closing the door causes the main 100mA RCD/ earth leakage breaker at the consumer unit to trip.
- Likely cause
- The discussion says the door interlock could be involved, but because the door lock then supplies power to the rest of the machine, the earth leakage fault could be elsewhere in the machine. No exact faulty part was confirmed.
- What fixed it
- No confirmed repair was given. The accepted advice was that tracing this type of fault requires an insulation test meter, so further diagnosis should be carried out by a suitably qualified appliance engineer.
- Checks to try
- Observed that the machine powers up normally
- Observed that the RCD trips specifically when the door is closed
- Parts or tools mentioned
- Insulation test meter
Safety: Do not bypass safety devices. This earth leakage fault needs proper testing by a suitably qualified appliance engineer.

Hi Ian. It's possible, but when the door lock operates it sends power to the rest of the machine so it could be anything. To trace a fault where the washing machine is fusing or tripping the electrics you need an insulation test meter which only engineers have. However, there is some help in my article here - washer fuses or trips electrics
