My Breville BES820 profesional machine has just decided to stop working. You turn it on and the lights come on (but it makes no noise). It also will do nothing if you press the buttons to get water through the group head, nor does it make any noise or do anything if you try and activate the steam wand or water wand.

I have no idea what has happened as it was working fine 2 days ago.

Any ideas would be much appreciated, it is out of the 2 year general guarantee, but is still covered by the 5 year pump repair guarantee. But i don't know what is the problem to start with.

thanks for your help.
