Bosch Excel 1600 Express. Replaced pump now drum not spinnin

[DermaShield]

The machine (Bosch Excel 1600 Express WFX 3267GB/11) was operating normally except the pump was not fully emptying the drum so I purchased a generic replacement and fitted it. Now the pump is working fine but the drum isn’t spinning!

The water fills and I can hear clicking noises as it progresses through its cycles but the drum doesn’t move at all and the motor is not running.

I thought that perhaps when I laid the machine on its side I may have affected some kind of sensor that stops the drum spinning if out of balance. Is this plausible?

With the machine in its operating position I have manually rotated the drum several times. I have tried this with the machine both switched on and off. The drum rotates freely and there aren’t any unusual noises.

Is it possible that a generic, rather than Bosch pump isn’t sending the correct “signals”?


Apart from that I’m stumped. Any suggestions please?

Cheers

The pattern pump has nothing to do with the problem.
Take a look at the brushes, make sure the motor connector plug is tight, & check the belt is in place.

Thanks Zipper.

Problem appears to be the brushes.
