My Neff S4453 suddenly stopped working. No power to the front panel at all. I pulled the machine out and checked the power into the back of the machine which I found was OK. Took the front panel off and had a look at the printed circuit board behind the buttons. One of the terminals was burnt out, a common fault I think. I re-soldered the terminal on. Switched the dishwasher on, nothing! Checked all the wires at the front of the machine for voltage. All of them dead. Machine has power going into the back and nothing coming out of the front. I can’t work out how to get to the guts of the machine and am loathe to start in case the problem is something that I haven’t thought of. Any suggestions anybody?
