Hopefully final update on this, I reworked the control board, replaced the triac and 2 resistors.

The machine ran for 3 cycles and then blew the triac again. I repaired the board again and did a detailed inspection of the loom. On a part of the loom at the back of the machine a wire had over time rubbed through it’s insulation. Replaced the whole wire end to end.

Machine now happily running again!

I found one at a company called Ransomspares for £118, does that sound about right?

see if they can repair it

On the front side of the board is 41033492

Does that help at all?

Thanks

Dave

Dave,

Thanks, to ensure accuracy I’ve taken a pic of the label.

its not smoke, see it all the time around high voltage components and these are operating at 300v DC

Dave

Dave,

Any further suggestions where I go from here?

Thanks

[Alex Facey]

It very looks like “magic smoke” evidence to me but okay, next thing then is I’m still no closer to knowing why it won’t run the drain pump?

All the help and suggestions are very much appreciated though guys!

Dave

Dave,

Thanks for the heads up, link has now been edited.

Sadly if that is the case then module damage has often occurred. A quick visual on the component side of the module usually shows signs of component damage. The water inlet hose from the soap dispenser often leaks as the adhesive sealant deteriorates.

Thanks for the advice, I’ll give the connector and control board a more detailed inspection and see what I can find.

Thanks for the reply, unfortunately when I disconnect the power and earth wires from the element it made no difference.

did it look like water had been dripping on it ?

dave

Dave,

No the pump looked okay and meters out okay, new pump displays exactly same symptoms of just never trying to run.

[Alex Facey]

Anyone got any suggestions please, all I can think of now is replacing the control board but don’t want to just throw money at it.
