Went on site today to refit the boards to the dish-washer.... all clear, works just fine, success, phew !
The not-for-profit organization I did this for, is so delighted to have their expensive dishwasher back, not going to the scrappy, they insisted on giving me some money ! No idea how much I will "charge" for that though ! Spent 15 Euros on parts + 8 Euros shipping.. but I get to keep 99% of the parts of course, and as for shipping, I ordered some UHF connectors for myself while I was at it so... I don't know, 50 Euros or something... that's barely the rate for one hour of labour over here, sounds fair enough, compared to the 1500 Euros price they were quoted initially to replace the mother board !
Anyway, I am glad I accepted to work on this dish-washer, was very interesting technically
