beko excellence WMB91242LC no data shown for programmes

[Aortic Mark]

Sudden onset failure of machine to show programme data as dial is turned, save for two wash settings. Machine does not start to run on any of the selections. Main Module pcb looked sooty, especially around one particular microchip; but when soot removed, no distortion or damage is visible. Rest of machine looks fine. Is it worth investing in a new module? Bought second hand, but trying to be green, so don’t want to give up too easily and the machine was running perfectly until it wasn’t.

Hi Dave,
Down to one programme, and almost certainly the last one used – mixed fabrics, 40°C, 1000 spin; could even be the ONLY programme ever used in our household!
Regards.

its not had the child lock activated by accident has it ?

Hi Dave,
That would explain everything and was not a function I was aware of; the machine did not come with the manual and I neglected to download it. I will check that as soon as I get home.
Thanks.
Mark.

Hi Dave,
Just checked the machine and, unfortunately, the child lock was not on, but it can still be activated and deactivated on any of the programme selections.
Regards.

Will do, but it might take me a couple of days to get round to it. Thanks for this advice.

Whilst I get round to tracing the wires, this is what I see when I turn it on. The yellow arrowhead flashes “ready” on all of the settings, it just was not captured in the second photo; pressing “start” has no effect. As you turn the selector, absolutely nothing happens (arrowhead is blinking) until you reach Mixed Fabrics, when those numbers appear.

press and hold start button as if your cancelling the programme

see if that does anything

the selector or the wires too it could be faulty

Dave

[electrofix]

well if you have not done already

remove each connector and put it back twice

if the contacts are dirty it will clean them

have you tried cancel button ?

Dave

[electrofix]

long shot

check motor carbon brushes

Dave

[Aortic Mark]

Unplugging, then replugging plus cancel button makes no difference.
How does the motor contacts affect the programme function?

[Aortic Mark]

Are the brushes accessible with the motor left in situ?

[electrofix]

tilt the machine back 45 degrees against a wall or similar and climb underneath

on some machines unit wont function if brushes lose contact with armature
