bosch maxx 1000 Motor not running

Hi Paul and Co., I'm a UK expat in the penal colony. I replaced 154740 brushes because one of previous replacement pair (by me 4 yrs ago) had ''disintegrated' the other was half worn in clean condition. However, with the new pair of brushes fitted still not turning? Have you seen this happen before? I could not see any obvious damage to the motor, but wonder if the damaged brush I replaced has damaged the motor in some way? Any suggestions?Alsowith another test today the motor does kick in and spin , but only in short bursts i.e.a fast spin briefly 5 times during the spin cycle , but does not wind up to a full spin in the usual way. It clicks on and off as per normal at the start/end. Lights all work as they should. Similar thing happens through the wash cycle - one fast burst of the drum spinning every 30 seconds through the cycle - i.e no slow continuous turning. Then drain kicks in as normal. Then spin as previously described until cycle ends Does that point to PCB or other?

I will try and help with this problem with Bosch MAXX 1000 washing machine.

First, check the carbon brushes are installed correctly, see video below.

If the motor gets hot above the safety cut out temperature then it will blow the Klixon 3MP  which I believe has an operating temperature of Maximum 180 degrees. 

I've made a video for you to show you how to strip down the motor and to test the parts and the thermal cut out you can buy these from certain places but it would usually be easier to find a second-hand motor.
