I have a Bosch WET2820 washing machine that has suddenly stopped
spinning. The M/C is six years old and when the same thing happened
about 12 months ago I simply replaced the motor bushes and it up and
running again. I've checked the bushes this time and they appear to be
fine. I've checked the filters on the water feeds and cleaned out the
vessel to which the outlet attaches and the suds pump fan is free to
rotate. My last attempt was to check the electric door lock and in a
desperate attempt to get it working I adjusted the sealed grub screw
which really messed things up because before that the machine seemed to
be going through the cycles OK but just not spinning, and now it's not
really not even letting water in. I suspect I'll have to get a new door
lock but does anybody have any ideas about or checks to eliminate any
other possible causes. (i.e. is there a way of checking the motor is
working ok)

I assume you mean spin as is spin dry, rather than just rotate during the
wash cycle. If so, check the water level sense system isn't blocked.

Usually, this is a thin pipe from the drain pipe to a pressure sensor- a
disc about 2.5" in diameter, located above the centre of the drum.. Air in
the thin pipe is pressurised (slightly) when there is enough water in the
machine to reach the drum. What often happens is that the thin pipe gets
(partially) blocked (scum etc) and the sensor "thinks" the machine still has
too much water in it to spin.

I don't know your model of washing machine - but when my old Electra
refused to spin last year it was down to an accumulation of limescale
in the pipework leading to the pressure (water level) switch.

I think the logic was that the machine was running the pump to empty
the drum - and wouldn't start the spin until the drum was empty of
water. As the switch never operated, the machine just sat there
forever waiting for it.

Fairly easily fixed - just find the switch, follow the pipework back
to the drum, remove rubber bits & clean.
An hour or so, lots of limescale / detergent crud, and a couple of
skinned knuckles later it was all working again - and has remained so
(touch wood!)

Do you always wash with cold water?
If so, do a hot wash to clean out all the crud that accumulates
in the machine.

Sorry, should have made it more clear, the drum doesn't rotate at any
stage, either when on spin or a wash cycle, that's why I thought it
might be the bushes again.

If I can work out how the door mechanism works and get it to fill with
water I'll give it a go. I guess it's usualy run at 60 for coloureds.

If it never runs the motor I think that will be a waste of time.

You need to check if power is being applied to the motor and work from
there.
If you know nothing about this then I must warn you that there are lots of
exposed live wires in most washing machines.
There is a serious risk of shock if you are not careful.

Reminds me of when I went to move mine and grabbed a very large
capacitor underneath by mistake ..Ouch !!!!

Correct, I've not really tried to test an electric motor before. I've
just disconected the electrics from the motor and attached a test meter
across the wires which should go to the two bushes. When I put the
machine to spin I'm not getting ant respnse at all from the meter. (the
meter was set to AC) although I would have expected some respone? I'm
hoping it's not the motor as a replacement is £175 + VAT.

You really need to do the test with the motor connected.
Some electronic controllers will give odd readings without the motor being
in circuit.

I've soldered wires to the bush terminals re-assemlbed the motor and
put it back into the machine but still no register on the AC test meter
on a spin cycle. Did the same test on an old hover motor and that
showed a reading.

Broken wire or duff controller by the sound of it.

Tracing the wire should be easy.
Testing the controller is probably hard.

If its like mine it will have relays inside that switch the mains.
You can test and repair these but it is hard to do so while still in the
machine and hard to connect when its not.
Mine has a test port on it to connect to a laptop but you need an interface
board and software to use it.

I expect the controller to be expensive. 8-(
