I have had a number of these boards with either the on/off not always operatng of the start/cancel intermitant working.

Althought the tact switch may feel ok the solder joints on the pins where it joins the module fail.

I carry a board so I can couple it up to the cable to prove if it is the switch and if it is carefully try to re solder pins or replace switch from scrap board

I have a similar problem with a indesit i have in for repair, you have to press the start button about 5 times quickly to get it to start?

Sounds like the switch its self or solder joint broken on one of the legs

New tactile switches are easily and cheaply available from RS etc.
You can also buy them easily in fives or tens on e-bay. Be sure to get correct type (SMD or through hole) and size by measuring up the old one.
The internal parts corrode in a damp atmosphere. And as Geoff notes they get a lot of abusive pushing so solder joints fail. On the WMA’s they used to fall right off!

If I have a board that has been fried then I will take off the switches from that to repair/replace the on/off switches in particular.

Can’t believe the amount of trouble you guys go to for the sake of recycling something that costs 20p. 😆
As I mentioned before, the switches corrode internally so even if a switch is not used it will probably not be as good as a new one. Plus with smds desoldering and resoldering a used switch you have to be careful not to melt anything other than the solder.
