Hello, thanks for your quick reply.
This is immaculate condition apart from these buttons not working, and I got it for a good price on eBay so I don't really mind too much if I can't fix it!
So far, I have managed to dismantle it up to the keypad apart from there seems to be this metal plate behind the keypad which I cannot remove. Do you have any idea how?
Edit: I have now managed to get to the buttons, however I do not seem to see anything wrong. Do you know of any other problems which effect the buttons not being read?
Edit2: After looking around, I think that the problem is quite deep so I have decided to give up. The other slight problem I have noticed is that the doors do not shut all the way, there is a gap, but if I push them manually, I can shut them. Is there any way to adjust this please?
