Have a siemens washing machine, front load.
(Model - Siwamat Plus 3381 - FD7106)

Stopped spinning.

-----

The brushes had worn to the wire. One stiff bearing too.
Replaced brushes. No change (still no spin).

-----


Got reconditioned motor from reconditioning workshop.

New motor on arrival has 8 pins rather than 6 on original.

6 pin connector from machine fits into centre 6 pins on motor.

New motor also has additional component lying close to armature in body of motor.
Looks like additional overload protection module?

Asked about pin mismatch and was told should work.

Pin 1 - connects to both sides of additional module
Pins 2,3 - 2.5ohms
Pins 4,5 - 3.1ohms
Pins 6,7 - 16.1ohms
Pin 7 - ?

(the old motor readings now (after new brushes) much the same as above except pins 4&5 read ~2000ohms)

Fitted it.

-----

Now...

When running through program, machine doesn't 'get into' proper spinning action.
Will spin drum about 1 single rotation,and then give up - intermittently, as it moves through cycle.

And when on final spin part of cycle, attempts spin but drum knocks about, and then the attempt stops.

-----

Any experience of this, or any ideas as to what's happening??
