ParticipantThanks for response Andy. It was the 3 brown wire PCB connector that was not seating correctly once pushed back into its proper place.
Now I’ve got it running however, the front concrete blocking is fouling the dispenser drawer though, especially as it winds up through the lower revs for the spin cycle. No clearance between them at rest at all and the plastic dispenser will be no match for the drum and block after a couope of runs. Can’t understand it. The dispenser is positioned correctly according to the locating lugs on the front, the top concrete block bolts are fully engaged in the locating grooves which means that the whole drum unit must be hanging a tad too far to the left looking from the front. The springs are relatively new, as are the drum legs, replaced by me a couple of years back. Maybe the support legs are just too weak to hold he drum in the correct position and let it sag a little, resting against the dispenser draw? 2 of the 3 are on that side. Any clues?nemonon123
ParticipantRe: Siemens WM12P360GB Spin Problem
Thanks gents, I appreciate the help.
Replacement carbon brushes were done 14 months ago when I did the first set of bearings.
Top’s off and springs look fine but there is s pronounced wobble as the drum starts to spin up. I’ve no idea whether that is as should be or not. Springs look fine and can access the imbalance sensor mentioned. For further diagnosis, if I was to unplug that sensor would it remove the protection and spin, or just default to a safe ‘no spin’?
Any way of testing the output voltage if that sensor to see whether it’s working properly or not?
I’ll try the simple and cheap stuff like brushes first on Friday and then have a go at replacing the imbalance sensor (£55!). Will let you know how this progresses.nemonon123
ParticipantRe: Siemens WM12P360GB Spin Problem
Back to square one: no spin after having manually drained at end of whites cycle this evening.
Any idea how these machines detect an imbalance during the load distribution process?nemonon123

Yes, it spins ok without any clothes.
I’m beginning to think it may be the more obvious drain problem. In a light mixed programme just now it spun up normally but then failed to spin at the end of the programme. So I drained the drum from the pipe at the front and the coin trap next to the pump and removed about 800cc of water which I figure may be enough to prevent the machine from attempted by to spin?
I have recently moved home and am wondering whether, after moving it into the new position, a slight kink in the drain hose (looks fine to me) might generate enough back-pressure to prevent full drain?nemonon123
ParticipantRe: Siemens WM12P360GB Spin Problem
Anyone know where the imbalance sensor is on this model? Definitely related to imbalance as it keeps just getting up to speed and then quits.
I’ll replace the springs and 2 remaining original dampers at least.
Any help appreciated as the missus is getting a little impatient with my make do and mend ways! -
