Re: Bosch WFO2855GB/01 no spin.
I’ve had this fault a few times when fitting non gen carbons. Fitting genuine bosch carbons has always cured fault. Looking at old carbons will always tell you if armarure is faulty in motor, look for burned trailing edge. This works on all carbon brush motors & saves a lot of time cleaning faulty armatures. Bosch carbons are cut more accurately and is why the machine does not abort spin.
