Older electrolux canister brush will not turn used reset button

Check the drive belt. could be broken. Not sure about reset button but i would say it has to do with the belt.

There is a reset button on the power nozzle...not sure I heard of the vacuum canister has a reset button....hum.

Make sure all threads, hair, and similar stuff is removed from brush, then try again.
Did you try switching the power nozzle switch off then on?
Does the power nozzle motor run? If not, and you've pressed the reset button, there's another problem. It could be a bad reset switch, or loose wires. There could also be threads or hair wrapped around the ends of the roller. This would prevent the brush from turning and shut the motor off.
If the motor runs, but the roller isn't turning, it's most likely a broken belt.
There is the possibility of the motor having burned out, but not likely.

A definite diagnosis would need to be made by a trained service tech at an authorized Aerus Electrolux store. The one nearest you can be found using the below link.

CHECK TUBE-SUMO ACTIVE ( PART NO: 1131402-02 ) CONNECTION AND NOZZLE-SUMO ACTIVE OR REPLACED (PART NO: 1131400-02)

Sounds like the belt on the beater brush has broke.replace the belt on the beater brush.

First thing is to push the circuit breaker button(reset button). If that dosen't work, check the belt. It could be broken.

Try hitting the reset button,It is a small button on the top of the brush and make sure the switch is turned on on the handle.

Turn the brush unit upside down, so you can see the brush roller. Then, with the brush roller positioned nearest to you, you will find the reset button close to the rear edge, near the wheel that's on the right hand side as you look at it.
Good luck! I hope this works for you. I value your feedback. Please remember to rate this response.

I am having the same problem .

There is a no filter safety device part #1130912-01, maybe the new filter isn't in quite like it should be or this device has gone bad. Also check the brush roll and make sure it turns easily, if not then that could be the cause.
