When i put hose in port it will not turn on...all the other ports work except one


Open the door on the inlet port and look inside. You should see 2 small pins. These pins are spring loaded to make contact with the metal end of your hose when you plug it in. Two low voltage wires are screwed to the underside of these pins. The low voltage wires go all the way back to the low voltage switch/relay on your central vac power unit.
Sometimes one or both of these pins will just break so that they don't make contact with the end of your hose. If you see no pins or just one then you will have to replace the inlet cover.
If both pins are present; push down on them with your finger. If you feel resistance then your inlet is probably OK.
CAUTION: IF YOUR CENTRAL VAC INLETS HAVE A 110 VOLT CONNECTION, REMOVAL/REPLACEMENT OF YOUR INLET SHOULD ONLY BE DONE BY A QUALIFIED ELECTRICIAN.
Remove the two screws in the faceplate. Carefully slide the inlet cover out. Check the two screw on wiring connections. Make sure both wires are securely attached and that there are no breaks.
If neither of the above fixed your problem, you may have a broken or disconnected wire somewhere between this inlet and the low voltage witch at your power unit.

I did not get a manual with my vac. I am trying to soak up water from a water tank leak and water seems to go right trough the vac and water is coming out the blower hole. the tub is not full.


There is a special sock that you need to buy for it. You can run the paper filter if your in a pinch but after that one time, that's it, that filter is ruined.
The paper filter is for dry vacuuming, the foam filter is for wet vacuuming, You have to have one or the other in place.
There are two ways to snap the cover onto the basket, only one is the right way.
Look to see that the baffle is facing the hose inlet hole.

My Hoover upright vacuum has gotten very loud. I have checked the roller, belts and hoses but I haven't found anything. What could the problem be? thanks


Most Hoover uprights are a "fan first" design, meaning that all dirt enters the motor , hits an impeller fan and is blown from there into the bag. You will need to open the vac, remove the belt and two C shaped clamps holding the motor in place and remove the 4 screws holding the fan cover. Look for a broken or damaged blade on the fan. It is a threaded fan and can be purchased at most vac shops. Reassemble in opposite order.

EF 1750 has lost suction power. There is a noticable decrease in suction power even at the power unit inlet.


Disconnect the actual pipe where it meets the vac. Then test the intake for suction. If you have poor suction still, check the intake itself from inside the vac body for blockage, then check the gasket on the pail for mis-alignement.

If you have suction at the actual intake, your issue will be in the house piping. Look for any damaged inlet doors which are ajar, also look at any inlets you may have recently removed for painting or renovation work. Each inlet has an o ring seal which must be properly aligned. If not aligned you will hear a hiss at the inlet when the door is closed.

Last check where any exposed pipe or pipe joint could have been jarred loose or damaged, basement , garage, etc. Post back to advise what you find

The wall outlets do not turn on. The motor runs at the unit. I have reset and it blows/sucks at the unit. The canister is empty. Thanks, Je


You main low voltage line from the vac to the house is likely disconnected. Start by looking at the connection where the small wires enter the vac. Touch across those two wire terminals with a screwdriver or needle nose pliers and the vac should start.If it does, inside the home those same wires run along your pie to each inlet. Somewhere along the pipe path the wires have been disconnected or broken.. Think back to any area where work has been performed or face plates removed for painting, etc. Remove each inlet one at a time and look for a loose connection on the screw terminal at the back of the inlets. When reinstalling be certain each wire is tidy and connected to only one screw terminal at the back of the inlet. Once all inlets are connected in line you will have a complete circuit back to the vac. Post back with results

I have a Nutone central vacuum model number CV450W that was working great until I recently removed the hose and it now runs continuously until I pull the plug....any suggestions please


Disconnect the thin low voltage wiring between the vac and the rest of the house. If the vac continues to run you have a defective relay in the vac motor housing.
If the vac stops you have a short in the wiring in the house, likely behind an inlet in the wall.
If any inlets have been disturbed for painting or renos lately that would be the first spot to look in the house for a problem. Look for wires behind the inlet valve which are touching against each other or a mounting screw or against a metal mounting plate behind the inlet. Start at the last inlet used. Be careful not to loose the spring under the screws where the wiring attaches to the inlets

Nutone CV556 Vaccuum Cleaner -Continuously running


Start with this. Unplug the vac to shut off, then disconnect the low voltage wiring at the vac.Plug the vac back in. If the vac still runs you have an internal short on the relay or wiring inside the vac.
If the vac stops then the vac and final wiring is OK and the problem is in the wiring in the house.
Have you removed any inlets for painting or had any renos done or pictures hung. If so undo what you did last. If inlets were disturbed remove them and look for low voltage vac wires touching metal backing plates in the wall or touching the inlet mounting screws.
If you have done a reno or hung pictures you may have pierece the wire for the vac creating a low voltage short which will keep the vac running until removed. I have seen this happen with freshly installed 1/4 round molding along a baseboard

Central vac toast?


Most of these motors, the fan cover is just pressed on, but getting off isn't easy and you don't want to bent it up. Maybe using a flatblade try to knock it off from the edge of it may loosen it enough to pull it off.

Bissell 3510 Vac with loud noise but not belt


Did you check the brush roll, may have a problem with it. But you could have a problem with a motor bearing going bad, they getting loud, also if there is a problem with the motor fan, that may be the cause of it being loud. Bissell 3510 either is obsolete or is thw rong number, it doesn't come up at the Bissell site.
