My Zanussi aquapulse de 6654 will not start. Only the on/off switch light lights.
Hi, I have a zanussi de6965 had the same problem the only indicator light that works is the on-off button.I had a problem some years ago with my machine would not work and showed L3 as the fault as I remember. I was advised to switch off all power isolate from the wall is best(pull the plug out of the socket) I removed the front casing held along the top and down the inside by a number of small screws. You need to leave the two bottom screws in(one each side) Wiggle free the top half of the display panel to acess the box holding the PCB board.it's very fiddly you will need a sheet of paper and a pen to make a noet of the connecting sequence of the wires ( Mark the blocks of wires with numbers... when replacing everthing this should eliminate any problems) Remove the PCB board from its casing and turn over to expose the back. At the bottom left hand side I discovered two dry joints, I needed a magnifing glass to check all the joints just incase. The faulty joints were a little discoloured blackened slightly. Solution...I cleaned, fluxed and re-soldered the joints. When re-assembled all the parts. It will help when dismantling to keep a note of the number and size of the screws and where they were removed from.
My dishwasher is now working again. hope this helps.
