Neff S6409N0GB/04 Dishwasher

[M1]

Neff S6409N0GB/04 stainless steel intergrated dishwasher.

No display on the program selction screen, buttons only beep when the door is closed, sometimes a electrial pulse for about a second then nothing for a minute. Suspecting the Module-control PCB which sits at the bottom of the machine next to the main motor ( but I am getting 12V DC to display program selector PCB)

Funny thing is this machine is 4 years old and been plumbed in the customers kitchen but never used, the customer said they switched it on years ago and the DW came up with select the language (standrdard set up when new), customer went into panic mode and switched the machine off. Sat for 4 years without use.
Any ideas ? anyone got a circuit diagram as the PCB is £145 +vat

Thanks

I think it’s best to check over the wiring harness connectors between the 2 modules, especially the main board. Corrosion to the contacts may have set in and a clean up may resolve the problem hopefully? 🙂
