Mike, I think I once had your enthusiasm!

all be it way back in the days of BT139 triacs or even massive thyristors paired with a massive diode,

you remember the old DC hoover modules then.
used to repair them even made a rig to check all the speeds where ok
simple days no programmed chips, no surface mount electronics you cant see, just plain old chuncky simple components

:boops: am feeling old now 😀

Electronics as a hobby is fine and I must admit I found the recent Miele power board fuse and relay thread interesting as I have puzzled over those no drum action faults for many years.

Hi Mark

Can you post the link to this Miele thread please.

Perfect Mark,

Had a couple of these in the past.

Much appreciated and thanks for making the effort.

Secondhand board from ebay finally arrived. But it was a bit different. I may put up some pics one day but for now I’ll just round off this story. It has a shorter user interface board laid out a bit different and the relays are 12v not 5v. Might have fitted, but I thought it might also need programming. So I gave customer a ring, explained situation and even suggested he try Hotpoints fixed-fee deal (hadn’t occurred to me till then.) He got back to me after a bit and said Hotpoint wouldn’t wear it (due non-Hotpoint staff intervention – fair enough) and the missus had decided to buy a new one online. So that’s another abandoned project but I’m not bitter 😆 . Learned heaps of things, not just about electronics but about negotiating deals for parts on ebay (got two s/h dishwasher motors on their way now) and not to start fixing boards without thoroughly examining first 😉 .
Mike.
