Hi Ashley - welcome to the Planet
I think there are two ways to attempt to solve your problem.
You could try a 'switch cleaner' spray, that you can use from the front face of the machine without having open up the machine. DO NOT use WD40 which, if i recall properly, will damage the rubber buttons inside the machine. There is a thread here somewhere as to which type of switch cleaner is OK to use (sorry can't find the thread at the moment), Does anyone else know?
If that doesn't work, there is good news and bad news.
The good news is that it is possible to dismantle the machines, from the back, and get access to the button pads.
The bad news is that you will have to take out nearly all the separate components, as the control button layer is the last layer you get to from the rear.
Lots of screws and ribbon connectors and boards, but it is possible and relatively easy (if a 2 hour job) to strip it down and reassemble. Take a deep breath, lots of photos and notes, keep the screws in some sort of order, proceed slowly and carefully and don't force anything!
I have a 'donor' machine, bought cheaply on ebay, that I have used for spares. I do know the switches are not individual units as such, but a whole board. Though you might be able to clean individual switches when you get proper access to them, it might be necessary to replace the whole board. I don't know for sure but don't think you can get 'new' spares easily for these machines these days. I might have the spares you need, as might others on the forum. Always worth asking.
Good luck - great machines and well worth keeping them working.
