Our Nautilus 920 Dishwasher won't turn on, what's wrong?
 
                Our Fisher & Paylel Dishwasher won't turn on.  When the mains switch is in the on position and the "ON" button is pushed, we only get 3 beeps, but no lights.  Recently we had a U1 Code showing, but after removing the strainer and pulling the machine out a touch, the code was removed and the machine has been working for a week or so.  Can this be fixed?
