Question about Bosch Classixx WFL 2066 Front Load Washer
Machine stopped rotating the drum and blew fuse and lifted MCB at some point in wash cycle. The direction/speed selection relays on the PCB are clicking in and out as they should and using a meter on the motor 6 wire plug I see 240V across pins 1(or2) and pin 3 and a switching 25V across pins 1(or2) and pins 3, 5 and 6 which switches from 0 to 25V The brushes were very worn and have been replaced and re-fitted twice. If I knew what volts I should see on the various pins I would be able to determine if it's the control card (not worth replacing at £180,) or the motor. I have not pulled the motor out myself so not sure if there is a taco device. Is the switching 25V expected? The only capacitor is on the mains inlet and I sassume nothing to do with starting the motor
The switching 25 volts is should be 0 when off and 25 when activated
I would measure voltage at the motor. If voltage is correct, then measure the motor with an ohmmeter and see what you get. You should have a strong reading at the motor. If not, motor should be replaced. Can you spin the drum freely by hand? If not, check the drum bearings

Actually, the Capacitor can short and stop the entire thing, Whenever a unit blows a fuse or breaker, it is usually something major, and is usually some form of short circuit, or very close to one.
As such, it can be an easy thing to look for as you are looking for a short circuit between Phase and Neutral/Earth... that simple... so meter out the Componentry until you find your suspect component(s).
The Voltage on the Pins may be OK, but the only way to know for sure is to consult a manual.
One really must get a service manual, as inside this are ALL Voltages circuits etc. I have Googled, but have not been able to find a manual, you may need to contact Bosch direct, I am sure they will supply you with a manual.
Below is a DIY self help washer repair website.
However with a unit such as this, it may simply be uneconomic to repair, as apposed to putting the money into the repair into purchasing a new unit, with a warranty.. Often these days the cost of repair is almost as much as a new unit.
