Any advice gratefully received:

So in our new house theres a washing machine.

It seems to work fine. It's plugged in to a plug socket in the kitchen
Whenever I turn it on, it goes for a minute or two then trips the MAIN house circuit breaker (not the local circuit circuit breaker).

When I take an extension lead and plug it in to another socket in a different room, it runs the cycle fine and doesnt trip anything.

Doenst make much sense to me...I'm sure this is a simple thing to sort out - but not for me.

Surely it should not leak any current, at any time, regardless of load ?

Pretty much everything has some degree of leakage. It all mounts up and so cumulative leakage can cause an RCD to trip. Especially if it is towards the lower end of its tripping current
