Is it displaying a fault code? In my experience that quickly narrows down the source of the problem. It will probably be a three character code on the display, starting with an 'E'. The codes, and how to get the machine to display them, can vary between models so you might have to do some Googling.
Espares has a handy list of what the different codes mean, and of course they'll sell you the replacement part:
