Hotpoint still tripping RCB

[Mcroycey]

I have a hotpoint wmxtf742 which tripped the rcb. I had a look and found the interlock had blow along with the harness plugged into it at the door end. I have just replaced the interlock and the harness with new parts. Turned the machine back on, selected a program and as soon as the cycle starts it tripped the rcb again. No damage to interlock this time though. 
Have I missed something in replacing the damaged parts?

I’d great fuel for some advice. Hopefully not looking at a new machine

Hi. Unfortunately you can’t deal with a fusing washing machine without a specialist insulation test meter. Even I wouldn’t be able to and I have 40 years experience. I have an article that gives a few tips on the main causes and possible clues though here Fusing or tripping electronics
