The drum in my Bosch Serie 8 washing machine stopped turning recently and after a bit of internet research it sounded like the motor brushes had worn down. I bought new "official" (allegedly) brushes from a reputable website and replaced them - the old ones were definitely worn down to nothing compared to the new ones so I figured that would solve the problem.
However, having put it all back together again, the motor is only turning intermittently in short stutters, makes an electrical fizzing sound when it turns, and gives off a faint burning smell like underneath the scalectrix cars I had as a kid.
I'm pretty sure I put the brushes in the right way round and reconnected everything correctly, but there's obviously something wrong somewhere.
Other relevant info:
I can't upload a video with sound, but here's an animated gif in case it helps:
The first time I turned it on and started a simple "rinse" cycle there was a flash inside the drum and it blew the RCD for the kitchen sockets where the washing machine is plugged in
I reset the RCD and tried again, and it's now doing the stuttering movement and fizzing thing
It happily draws water into the machine - it's just the motor / drum not turning properly
Is this possibly a problem with the new brushes, or my fitting of them? Or should I play it safe and just replace the whole machine?
Any help / pointers welcome...
