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,
