Hi,
I have just bought a flat with a DWF415 dishwasher, trying to make this work and perhaps you can help.
It starts, seems to take in water then after a few mins, pumps it out and the indicator lights flashes 7 times.
The service number is 8545 415 15710.
Serial No. is 330446003276
I have cleaned all filters including the one in the water hose and in the water inlet to the dishwasher. In the hose connection at the back of the washer I found a purple plastic non return valve which I have removed as it was positioned such that that water would never have entered the washer!!
All help appreciated.
