Hi does anyone have any tech info on Neff 7871n0bg03 combi oven. Customer brought one in claiming F4 on screen after power cut. Unit powers up display flashes with the usual zeros, then fades away and unit is inoperable. Not sure which board to suspect. Any help greatfully received
check the main relay board tracks. The lamp can blow the puds out of it also the steam flap actuator can do the same. Problem is it can flash over to the display boards too.
