WT540/1p Module Fault

[aqua_serve]

Guys

I wonder if any of you could point me in the right direction. I have a Mk 4 module for a Hotpoint WT540. The casing for the module shows a blow around the R20, D9 / D2, L1 area on the board. My question is what would cause this? I’m thinking the interlock although I haven’t yet tested this. I’m hoping to try and gain experience of board repairs so would really appreciate your thoughts.

It’s no major repair job as it’s only a friend’s machine used for dog blankets. WOuld be great to boost my knowledge though.

Mark, a photo of the module damage would probably spark off some attempts to answer your question. Few of us have access to spares of such things in stock and if we did it would take a lot of hunting to find the components you mention. Posting up photos here is easier than ever, even I can do it so it must be. (There’s probably a tutorial on here somewhere; I wouldn’t know how to tell anyone else to do it as yet.)

Hi Mike,

Thanks for the advice, here is a link…

What I’m actually looking for is someone to tell me what Relay labelled K2 (the black one) does.

Any adviee would be great.

Sorry been away from boards for a couple of months and just going through old reply notification emails.
Look at bottom of relay from other side of board. There are three legs one end of the rectangle and two the other. At the three-leg end the two outer ones are the coil. The middle one is “common” and switches between contact with the two at the other end. If you see which of the terminals in the main connector block are connected to the switched legs (end with 2), then follow the wiring from that / those terminals, it may point at something.
Though I guess the dogs’ blankets must be mingin’ by now.
BTW, a burn mark on the module casing may not necessarily be from the current module.
Mike.
