We had a cleaning crew come in and they used our Miele Flamenco II vacuum. Apparently, it never crossed their mind to change the bag, so when it became overfull the vacuum overheated and shut down. They brought me the stuffed bag and asked me to change it for them. As I was doing so, I noticed the vacuum was really, really hot and there was a burnt plastic smell. When I got the new bag and filters in and hit the power button - nothing. I assume some thermal breaker had cut off power to the motor.
A half hour later I tried again and it did kick on and suction seemed ok. However, on shut off not only does the blower spinning sound ramp down, but also the motor now whines as it spins down - something I am certain it did not do before.
I am concerned that the event has done heat damage to the motor or nearby plastic/rubber parts resulting in a shortening of the lifespan of the motor and possibly creating a fire hazard. Are my concerns misplaced? Should I replace the motor?
Thanks,
