    Bosch WVD24520GB/05 washer drier. FD8903.

    Well, not completely dead. Display lights up with just the horizontal lines; no digits or symbols. Will not lock the door or do anything else. No response from buttons; control knob just turns display off and on – nothing more.
    If the display is faulty, then surely the machine should still at least respond in some way? I am thinking main PCB (00674052) has died.

    Any help please!!

    Thanks,

    Steve.

    On some of these, not sure on your model, out of circuit motor causes display issues.

    Thanks Tim for the pointer – brushes were worn down to nothing. Fitted new and tried it again – still nothing apart from lines on the display. I tried resetting it using the F21 fault reset technique but no luck.
    Anyone know how to reset this range of Bosch PCB’s….or is the board goosed as well?

    Any help greatly appreciated!!

    Thanks,

    Steve.

    These arent 100{e5d1b7155a01ef1f3b9c9968eaba33524ee81600d00d4be2b4d93ac2e58cec2d} bosch dna, i remeber delivrring these and they came in boxes much like the integrated bosch w/ds which were italian (smeg) rather than the shrink wrapped polystyrene so id imagine the f21 trick may not work.If its a bsh motor check the toc hasnt gone, doubt display pcb is an issue as controls are on control mod, disp pcb is purely a lcd block. Could be the main mod where motor relay is. If thats case the control pcb wont affect it as itd be flagged on self test startup. Noted recently a lot of wvd24520 24460 parts ive fitted are now chinese made, bearing cross etc. Have you checked pcb isnt covered in carbon dust? Repaired a bosch last month where it would boil everything and seems carbon dust was bridging a few tracks and bypassing the heater relay control!!
