Re: vacuum shuts down after 1 minute , lights on
It does sound like your control valve is bad. I would suggest taking it to your Aerus dealer, because it shouldn't be that expensive for them to fix. Plus, I'm not sure if you can get the part fom anywhere else. That's the only place I've ever found them. If you don't have a dealer around, you may be able to call their corporate HQ and get them to ship you the part. The control valve sits right under the dial knob on top of your canister. You have to dissassemble the entire unit from the bottom up to get to it. It might be a bit much if you aren't pretty handy. But if you really want to, open the front of the canister and remove the bag. As you are looking at the front of the unit, there are two vinyl coverd strips that run the length of the unit. Pull forward on these strips and then pull out so that the vinyl seperates from the plastic underneath. Now grab the plastic strip with a pair of needle nose pliers and pull towards the front of the canister. These can be tough if the machine has never been opened up before, but pull as hard as you need to, to slide the strip out. Once both strips are out, turn the machine over, pull out on the sides of the bottom of the unit, and lift up. The bottom should come of relatively easily, and eveything will be exposed. You will now have to remove the cordwinder, motor, and bag housing. Under the bag housing you will finally see the control valve with vacuum lines attached to it. Good Luck!!

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!
Electrolux uses a pressure differential control valve. This valve measures air before and after the bag. There is a orfice or small hole where the hose connects to the vacuum cleaner, and a orice at the back of the bag canister. As the bag fills up the suction pressure reduces at the hose connection and increases at back of the bag canister. When this happens the control valve has a diaphram that closes, which shuts the vacuum off and gives you a full bag light. There is a thin plastic flange that prevents an o ring on the control valve stem from coming off. The flange breaks, the o rings comes off the stem and the vacuum will shut down indicatiing bag full. The after market price is about 22.00. The valve is easy to replace if you are familiar on electrolux vacuums. When I replace these valves, I use epoxy two part plastic putty on the flange of the valve. It takes 2 days to cure, but the flange will not break.
It sounds as if the motor has overheated at some point, and damaged the thermal protector fuse in the motor compartment. Clean the filters thoroughly, change the bag, and try to operate it. If it still shuts down, the thermal protector will need replacement. ( Part # 47534032 )
Check the afterfilter. If it's dirty it can cause this. Try turning the vacuum on with the filter off.
If this doesn't help, the problem is probably with the Control Valve Assembly, or a tube connecting to it. This is the part that the dial connects to. The tubes often get clogged and need cleaned periodically, especially if generic ("made to fit") bags are used. The CVA itself may also be worn out or broken.
For cleaning, repair, or replacement, the vacuum needs to be taken to the nearest authorized Aerus Electrolux store. The service tech should also do a thorough cleaning and, at your request, preventive maintenance on the vacuum.
This is most probably due to a worn out or clogged Control Valve Assembly.
Detach the hose and see if it runs. If it does, place hand over hole. If it shuts off, CVA is probably the cause. A clogged CVA is generally due to using generic/made-to-fit bags. Genuine bags have "Home Solutions" printed on them.
You can try turning the dial all the way to the large dot, then try to run the vacuum.
If it is the CVA, you'll need to take it to an authorized Aerus Electrolux store and have their service tech repair or replace the part. I recommend a service and clean of the vacuum at the same time. This will extend the life of the vacuum.
Try dialing the control valve to the mid way position. If the unit still shuts down with the bag full light on you have a damaged control valve under the dial on the top of the vac. This valve failure is common in this model and can only be repaired by someone with original AERUS Electrolux repair parts, generally at an AERUS repair shop.
Actually the problem is inside of the canister itself. You need to change a part called the control valve. Occaisonally when fine particles get inside of the valve it damages the inside of the valve, sending a false reading to the main motor, causing it to shut off. This is a relatively quick and easy repair and should be recieved on a same day basis.
It sounds like you have a motor protection fuse that resets after an overheat/cooling cycle.These work the same as a circuit breaker in your house with the difference being they can reset themselves.The Bosch will also shut down if there is insufficient airflow and I would check your filters first.1) Pull the filter and let the machine run.Do not pick up debris when you operate without a filter-it will be drawn straight into the motor.If it runs fine without shutting down, all you need to do is change your filter.If it shuts down again check the external hose for any blockages.Also check the throat from the powerhead for any blockages.If you continue to have the same problem then you will need to replace the fuse because at this point you have eliminated all the other likely problems.Good Luck-Scott
Actually the problem is that you need to change your control valve. The motor has an internal thermostat on it already so the chances of you burning the motor out are very slim. By changing the control valve, you will solve your problem. Very simple and quick fix.
