Hi, Tecnik fully integrated dishwasher, model number on door: SE6TIE2GB/46 FD8405. It is made in Germany, a Bosch machine I think and about 12 years old.
Dishwasher has suddenly developed a fault where it will not start the program cycle.
Symptoms: After closing door to start, there is a periodic clicking sound emanating from the control board in the door located just under the program selector buttons. This is accompanied by a clunking sound as the cold water supply inlet valve opens and immediately closes in time with the clicking from the control board.
I have removed the water supply hose and checked the strainer filters are clear of debris, so no blockage there.
Any advice would be much appreciated.
