When turning on vacuum with out hose it is fine, put the hose on and it shuts off and the change bag indicacater comes on. If I turn on the vacuume with out the hose it will stay on untill I put my hand over the hole used to connect the hose. I've changed the bag 3 times and replaced the filter. There is no clog what so ever. Help
If you want to fix this problem gently pry up the air flow control knob and look down at the plastic hose connected below the control valve. insert a small screwdriver and push off the hose from the valve. this disconnects the bag full indicator but will let the vacuum operate normally at full vacuum. you will change the bag when suction gets low. this will save you at least $100 repair bill.

it may be over heating.Check to make sure your hose and power nozzle are not plugged..Simply turning machine on without the hos then putting hose on while running and see if the motor sounds different,ie.winding up higher.....if this doesn't help try changing the bag
Symbols..Question mark means "Put a bag in me", checkered light means : "Change me, I'm dirty"....pre-lit power light means: "You have Powaaa" to the unit and the thermostat light means the motor is too hot if it comes on, (most likely from a hose clog) and needs to cool down before the motor will run again. The settings on the control valve basically have to do with the auto shutoff when the bag needs changed. The lower the valve is turned, the more full the bag will get until it shuts off. Hope that helps!
1. Detach the hose and turn on. If it runs, place hand over opening. If it shuts off, the control valve assembly is dirty or worn out and needs cleaned/replaced. This is a job that should be done by an authorized Aerus Electrolux service tech. It's most commonly caused by use of "made-to-fit Electrolux" bags, rather than the genuine bags made by Home Solutions.
2. If the vacuum keeps running after detaching hose and placing hand over in port, then check the hose. Drop a coin or similar small item through the hose. If it doesn't go through, there's a clog. It will probably be at the bend of the handle. Plug hose into exhaust port and turn vacuum on. Make sure the other end of the hose is in a bag to catch the dirt and stuff coming out. If you have problems, it's easily removed by a service tech.
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.
It's possible the thermal reset is defective. It shuts the motor off if it gets hot. Remove the bag door and take the bag off, remove both filters and then turn the vacuum on, just leave it sit there with the motor running. This eliminates the bag or filters causing any airflow resistance. If it still shuts off after a few minutes it's likely the thermal reset is bad. Some vacuums have an external thermal reset button which can be replaced if necessary but on your model it is built into the motor and you must replace the motor. If the motor runs fine put the bag and the filter under the bag back in - (make sure the filter is clean and not restricting airflow) put the bag cover on then turn it on again. If it overheats and shuts off then you may have a clog on there somewhere restricting the airflow. If so check the power nozzle area, the hose coming from the power nozzle, the extension hose and wands for clogs or restrictions.
This vac is prone to a control valve failure with the exact symptoms you describe. There is a dial valve on top of the machine designed to regulate how full the bag will get. The valve which sits underneath the dial on the vac likely has a broken plunger and will need to be replaced. Take it to an AERUS Electrolux dealer / shop for an experienced tech to work on.
I'm not sure if I understand your problem completely, but if it is your full bag indicator that is coming on, even with a new bag, it's probably your control valve. These can be replaced by your dealer. When working correctly, the control valve should trigger the off switch when the differential pressure gets too great between the front of the bag housing and the area behind the bag. When it goes bad, it will indicate that you need to change your bag, even when you don't. Good Luck!!
