I have a Firenzi FIDW 42 dish washer which stopped working its about 3yrs old put has rarely been used. There are no lights on indicator panel on the top of the door, but when I keep the on/off switch pressed on one of the program lights flashes on then off and the inlet water valve opens and the pump kicks in, as soon as I release it stops. The Manual says the end program light should be on in normal operations until a program is selected. Any help appreciated.
