Put the vac on it's side and pull off the sliders on both sides.Carefully pull machine apart.lift the front of the piece that hold you bag.Underneathe there is a clear tube plugged in to a round thing on switch area.Simply pull the tube out of the rouind trhing.This will allow you to fillthe bag without shut dow.Just make sure your bag doesn't get too full....Chris

The dial on top of the machine should be set about mid-point. If it is, then turn until the small dot and the arrow are lined up. If this doesn't help, turn all the way around so large dot and arrow line up.
2. Detach hose from vacuum. Turn on. If it continues running, place hand flat against the intake. If it shuts off immediately, there's probably a problem with the "Control Valve Assembly". This is a part that can be purchased at your local Aerus Electrolux store. I highly recommend allowing them to replace it rather than trying to yourself.
If you don't know where the closest store is, go to aerusonline.com, click on "store locator" button at bottom of page, type in your zip code and click on the find store button.

If your vacuum runs fine without the hose attached, then check hose and power nozzle for a clog.

If the bag full light keeps coming on, you can first try adjusting the dial on top of the vacuum cleaner. If that does not work, then you need to change the control valve. This is an internal component of the canister and is directly below the dial. You will need to follow the instructions on a previous post to open the Electrolux plastic canister vacuum, and remove the bage cage. Once you remove the bage cage you can change the control valve, and this will solve your problem with the bag full indicator.

This is exactly the symptom you would expect from a defective bag control valve. The actual control valve sits under the dial on top of the vac and often cracks internally. It can be replaced in about 15 minutes by a good tech with genuine parts from AERUS Elctrolux dealer or repair center.
You can open the vac front to rear like a **** shell by sliding the bumpers out the front with the bag door open, however you must be careful not to disturb the wiring harness and to mark wiring locations. The body must be carefully realigned for closure. If it is not perfect you will not be able to slide the bumpers back in.

it might be that the hose connections are bad.or it might be a sensor in the vacuum. call a electrolux vac shop and get it looked at.

is there a filter in it if so clean the filter.try it without the bag in it.make sure the bag is in correctly.does the bag expand when you turn it on.you might have something caught up in the hose.take the hose off and blow througfh it.if you can't its clogged.also check the inlet where the dirt goes into the bag.the inlet might be clogged.please leave feedback
