Question about Electrolux Vacuums
This is an older Electrolux Prolux Plus Upright (model #: U111A). I\'ve never had any problems with the vacuum. However, when I replace the bag, the full bag indicator will not reset (meaning the orange goes away on the indicator). Mode 1, bare floor, will not work at all and Mode 2, it doesn\'t suck properly. The dirt goes about midway up and that\'s it.
Your top motor (suction motor) isn't running. Your vacuum has two motors in it. The top motor is the suction motor that runs on the first switch position and the bottom motor (brush motor) turns on with the second possition.
It could be the switch.If it isn't the switch, the only other thing it could be is the motor itself.
To check the switch, unplug the vacuum and then take the three screws out of the back of the handle. If you are comfortable with electricity, jump the black wire and the blue wire togeather and plug the vacuum into a electrical outlet. If the motor dosen't run, the problem is with the motor. If the motor runs, the switch is bad and needs to be replaced. You can get one at most any vacuum shop.
The motor could be bad or the carbon brushes can be stuck with dust. This is more involved and I recomend taking the vacuum to a vac shop that works on the "old" Electrolux vacuums. The new name for the "old" Electrolux is now Aerus Lux but you would probably get it repaired less expensively at another vacuum shop.
If you want to go into the motor housing you'll have to take the big screw out of the back of the handle and pull up on the handle to remove it. Next, remove the four screws holding the top half (motor housing) of the vacuum. Two screws on the back and two screws to the front inside of the bag housing. You'll need a long #2 phillips screw driver. Then pull up on the bag housing with a side to side motion.
With the housing removed, you will see the motor and can lift it out.
Check for any bad winding. You can smell them to check if you can't tell by looking at them. If they are burned, you will need to replace the motor.
To check the brushes, you will need a 5/16th" socket to remove the two bolts on the top of the motor and lift the top bracket with the carbon brushes off and see if the brushes move freely. If not moving or not long enough to touch the top part of the motor with the copper bars (the comutator) it would be best to replace the motor.
To reassemble the vac just reverse.
This is a long and difficult prosedure and I reccomend that you take the vacuum to a repair shop that works on the Electrolux.

The problem was a sticking switch that was not being reset. The vacuum on/off switch mechanism is comprised of two switches. One is the main switch that turns the vacuum on and off. The second is a shut off switch that gets tripped when the full bag sensor is engaged. This second switch is supposed to get reset when you push the on/off switch on the outside of the machine. The full bag shutoff switch was stiff and it, therefore, was taking a couple of presses of the on/off switch to move the shutoff switch back into the running position.

You shouldn't have to remove disassemble the powerhead.
Lay vacuum on it's front. Between the tank and the powerhead is a black flex hose. Pull the end straight out from the powerhead. Then unscrew the tube from the tank using a clockwise turn. Remove the tube and visually check for clogs and splits. Clear or replace as needed.
If there's a clog in the powerhead behind the brush, this can be cleared using a wooden spoon handle or similar object.
If there's no clog in either place, there's a couple other possibilities. First, turn the vacuum back upright, open the hose flap, turn vacuum on, and place hand over opening to check for suction.
If there's a lack of suction, the bag needs replaced, the afterfilter beneath the bag needs cleaned, or the motor needs replaced.
If there is suction, put a coin in the opening inside the port and to the right as you're viewing the front of the vacuum. The coin should drop to the floor. A clog in thes section is unusual, but can happen.
If there is still no suction, take the vacuum to the nearest authorized Aerus Electrolux store for free diagnosis.

I opened the case and watched the full-bag switch in action. It reset every time but still failed when the hose was connected. I saw nothing to suggest that five on-off cycles of the switch would reset anything, but tried it five times anyway. I tried taping a bit of foam at the end of the bar the vacuum switch moves and it worked fine for about five minutes after reassembly. I gave up, popped it open again, disconnected the clear hose from the vacuum switch and plugged the end of the hose leading to the dial control so that it wouldn't be a constant bleed on the vacuum. When it begins to lose suction I'll check the bag just as I do on other vacuums.
