Motor sounds like it is trying to run, but nothing happens. What is wrong?

Possibly water went into the motor are a new motor will now be required. Either way the motor sounds past its best.

Hello, my Miele Olympus was running, then stopped all of the sudden and it smelled. did not turn on since. Does that mean the motor has gone bad when it starts smelling ?

It could be a short somewhere, it could be the carbon brushes in the motor need replaced.

If it was just a broken belt you would still hear the motor running. most likely its in your cord or switch. check the main cord, connections to the switch, and also the motor supply cord that goes from the handle to the vacuum head.

the water basin has a safety on it so the unit cannot run without it. if you look on the bottom of the rainbow you can see a small oval shaped space that you can depress just to test and see if it still runs it will only run with this depressed.

This little vac I think is actually made by Samsung. If it is ROARING and vibrating, either the bearings or suction fan is in bad shape. Remove the lid as if to inspect the belt and see if there is a visible intake opening with a plastic fan rotating inside. If so you have to inspect for damaged fan blade . A broken blade will cause the noise you describe and can be fixed on most vacs by carefully opening the fan housing and unscrewing,the fan from its threaded shaft. Then screwing on a new matching fan. Post back with more info and I`ll try to walk you thru the process

if the motor doesn't run sounds like you either have a bad motor or your motor armature might have gotten wet and created a dead spot.if you have any contact cleaner spray a little on the armature then turn the motor by hand make sure its uuplugged first if you can turn the motor then plug it in and try to start it

Circuit brealer switch may be bad, but the fact that Rainbow nozzle made this strange sound makes me think that it may have happened because there is something wrong with the motor.

While unplugged - remove the brush and belt. Try turning brush ends - see if they yurn easily... Try turning the motor shaft - see if it turns and if it does - if it turns smoothly and if makes any strange sounds...

To really test the motor you can just bypass the circuit breaker switch.

did you ever find out the problem with your rainbow? Mine did the same thing today- turned on the switch yet nothing happened. Think it needs a new switch???? Do you know how to get canister apart after taking out first screws?

There is a switch, but could be a bad cord, or the motor went bad.
