Question about Electrolux Centralux Vacuum

Lack of suction at power unit

I have an Electrolux Central Vac system (in a house that we just puchased). I have went through the Troubleshooting flow chart and got to the power unit and pulled the tube off of the inlet and found that there is very little/no suction at the power unit (even though there is a ton of air flow coming out of the exhaust).

    There is no suction right at the power unit (canister in the garage). I pulled the PVC piping off at the inlet and there is no suction there even though the motor is running and the exhaust of the unit is blowing out excessively hard, even if a plug off the inlet.

    This is with out the vacuum even hooked up to the house piping, so how would the house piping even have anything to do with this? I have tried this right at the unit in the garage I can put my had across the inlet right at the caninster unit and there is no suction at all.

    I am having suction problems with my Electrolux Central vac. I have got as far as pulling the piping off of where it comes into the inlet of the main unit. I can put my had across the inlet and there is very little/no suction, but yet the exhaust comes out extremely hard.

  • Joeayres Nov 15, 2007

    I have checked for leaks, I removed the cannister and the filter. I noticed that there is not any gasket/seal where the storage tank mates up with the motor unit, I have also checked the gasket/foam seal in between the motor and the tank and it appears fine. The volume of air that is coming out of the exahuast feels like one of those shop vacs that you can use as a blower as well.

If you have remove the piping from the inlet of your vacuum and by clogging the inlet with your hand to feel if it is sucking air but still little/no suction is felt then there must be a crack from the inside of your vacuum unit where most of the air being sucked is passing through and bypassing its inlet. if there's a possibility for you to open the unit (unplug it first) then check for possible air leak passages from its inlet to its exhaust! check for loose air seal also!

    this are common air flow concept of vacuum cleaners.
    from the inlet air is sucked through the motor to the exhaust.
    make sure that no other possible opening for air might pass through (loose bucket where dirt is stocked, holes, seal gaps)
    test the system for a moment with its bucket unplaced/unloosed then see if there is a change of exhaust air pressure. (be careful....) make sure nothing is near enough even your hands from the intake/inlet/motor.
    does air exhausted increased? turn off the unit!
    carefully check for cracks/hole on its bucket! place everything on place. make sure also the the inlet wasn't block by anything. make sure also that screws/ lock are tightly (controlled) placed.

    make sure that the bucket is fitted/closely locked/tight
    to the unit!

Check that the Handle has a slider to adjust air flow, Electrolux Vac's arent really designed for carpet cleaning, check hose for breaks or cuts and everything is secure, while its on run your hands all over the hose and vac to locate any air flow that should not be.

Let me know.

    then there is either a plug in slot in the house that is open or a brake or disconnected line under floor or in wall which ever they ran the lines.

    If you are unable to locate the break or problem causeing the suction loss, contact the seller or manufacturer for service. Since itss new you should have a warranty.

I would recommend checking your wall outlets where the hose plugs in for any type of clog in the tubing. If the vacuum itself has great suction but when you go to the wall outlets that is probably something in the hose that is stuck. If cleared it will most likely have excellent suction throughout the entire system in the house.

Low suction


1) Have you checked the filter? If it is clogged your suction will be low. Also, you could have a pipe loose where you can't see. Make sure that you can get a coin to go all the way through the hose. make sure the suction motor ( the unit ) is coming on.

2) Call the repair man.

No suction but good exhaust flow


This sounds like you have a loose pipe connection somewhere in your system. Physically check all connections. If you can't find anything suspicious, call a vac repair man that specialies in central vac repair. Joe

CENTRAL VACUUM SYSTEM


Disconnect the inlet piping from the unit and check the suction there. Be sure that the utility inlet on the unit is closed. If you have good suction, you have an open/broken pipe somewhere, or possible an inlet valve or vacpan that is not sealing when closed. The easiest way to find it would be to install your tubing back into the inlet of the unit, turn the unit on, and walk around the house listening for air leaks. Good Luck!!

Dust....dust....dust
Posted by Kitkatman on Jun 11, 2008
Hello,
I recently bought a house with an older Electrolux Central Vac system. I'm unfamiliar with them, so I'm not sure how to deal with this: I cleaned up some mortar dust with it, and noticed not too long after that when I went into the garage, there was a fog of dust. The hose from the unit is venting into the garage. Is this normal? I have since used it for everyday household cleaning and each time I go back to the garage to a cloud of dust. Is there anything I can do? Thanks


Hello,
I would advise you to ALWAYS to FIRST UNPLUG YOUR VACUUM before beginning any service procedure. It sounds to me that the unit you have may have to be vented outside as I am not familiar with this particular unit, or it could very well be that it is missing a filter or the filter you have inside already is shot and is in need of replacement or on some central vacs there are paper filter that go over the cloth type filter. Again, I am not familiar with this older unit but feel free to contact the Electrolux Factory or Manufacturer and give them the model # and the serial # for the unit and they will have a breakdown of if it should be vented and what type of filtration it should be using. So if you need further assistance, please feel free to contact your local vacuum cleaner dealer in your area or in the yellow pages, or contact the factory phone number or website to further assist you with your questions.

Electrolux central vac problems


I work on many types of units. If you electric floor brush runs but you have no suction then there is possibly a problem with the relay board that allows you to turn on the suction from the hose handle. This is a low voltage (24 V) switching loop circuit that will cause the 120 V motor in the unit to run.

Inside the wall valve are two brass pins. NOTE: there are 120V valves installed on some systems known as a Super Valve. A shock hazared exists if you work on that type of valve. That being said. In the round portion of the valve you can use a garage hose that has a 360 deg. chrome ring to test the valve. The ring completes the circuit causing the unit to power up and suction at the end of the hose. If the suction is weak, there is a colg in the pipe. If you hear no airflow, the relay inside the unit did not energize or the motor is bad.

To test: go to the unit and turn the switch on the side to "manual" if the unit turns on the motor should be ok. DO NOT RUN THE UNIT without and open valve. In some brands dammage to your motor will occure.

If the unit did not run, look for a small button near the switch. This is a circuit breaker for the motor. If it is poped out and you hear a "click" when you press it in there is most likely motor problems and someone should be contacted for repair.

Hope this helps!!
