Question about Vacuums

We just installed a Hoover central vacuum system. As soon as we plug it in the system starts even if the switch is off. If we disconnect the wire the system goes off. What did we do wrong?

You have either left the manual switch at the vac in the on position, or you have a low voltage short at one of your inlets in the house, or at the vac itself or where a pair of wires are connected together at a pipe junction.
Carefully go back inlet to inlet, remove the plates and be sure your mounting screw is not shorting two wires together. Trim any excess bare wire away and look for nicks in the insulation as well unless you see an obvious short. If you are using telephone type multi colored wire it is easy to bare an inside piece of wire while stripping the outer insulation.
Also be sure sure wires are paired the same color pattern at each inlet.
It is common to see a stripped wire touching another inside the wall or if you have metal backing plates in the wall a wire may be touching the plate and triggering the vac to turn on. Post back to advise,
the other possibility is you have a nail or screw in a wall piercing the wire but this is seldom ...
take your time,its an easy fix but it might be hard to spot

My home has a central vacuum system hook-up but no vacuum installed. My friend upgraded his central system and gave me his Eureka Mega Boss central vacuum system and the accessories, including the pow


The power head requires 120 Volts. Some hoses have a receptacle in the handle for the power head plug, and the hose has a cord at the wall inlet end that plugs into a receptacle. Some hoses have a plug at the wall inlet end that plugs into a 120Volt receptacle built into the inlet. The hose plugs into this receptacle when you push the hose into the inlet. The power for this built-in receptacle is wired with line voltage when the system is installed.

Our Easy-Flo built in vacuum system will not turn off, even when the hose is disconnected. We have to turn it off manually. Could it be a short in one of the wall outlets causing this?


Some models have an on/off switch on the power unit itself. This switch is used to turn your power unit on when you are right at the machine.
If there is no switch on the power unit, unplug your power unit from the wall socket, look for two low voltage wires coming out of the power unit. These two low voltage wires are usually either attached with terminals or are tied to two wires coming out with plastic screw on wire caps. Disconnect the 2 low voltage wires. Plug your power unit back in. If the power unit does not come back on then yes, the problem is most likely a short in the outlet wiring. If the power unit still comes on with the 2 low voltage wires unattached, then the problem is in the internal circuitry of the power unit, usually a relay or some units have a circuit board with relay, circuit breaker and other components on it. The relay or circuit board will have to be replaced.
It's a little difficult to check for a short if you have multiple outlets, but if you've recently done some renovations you might start checking in that area.

WIRING IN 24 VOLT INLET VALVE FOR CENTRAL VAC. I GET A CONSTANT ON. I HAVE TRIED MAY DIFFERENT COMBINATIONS BUT I CONTINUE TO HAVE MY CENTRAL VAC AS A CONSTANT ON? COULD IT BE THE 24V WIRE?


No, there is only two possibilities. One, the low voltage wires are touching somewhere in the system or two, the relay is stuck in the on position. To find out which it is disconnect the low voltage wire from the unit (theres two clips on the side) and then plug the canister in. If the it still runs with the wire disconnected then it is the relay board. If it doesn't then it is the low voltage wiring in the system. Good luck!

NuTone Central vac won't turn off


If the central vacuum tank will not turn OFF even with the switch in the “OFF” position, then the low-voltage wires should be disconnected from the tank. If the tank continues to run and still will not turn off, then most likely the relay inside is defective (but it could be a defective and/or shorted ON/OFF switch). If with the low-voltage wires disconnected the tank is able to then be turned off with the switch, then there is a short in the low-voltage wires or a hose is plugged into an inlet somewhere. ~ TTURAMBAR

NuTone CV353 Central Vac does not start when hose is plugged into


Try to plug the hose in sideways. So the top of the hose is rotated 90 degrees. If the unit turns on then there is something wrong with the hose. It might be a short or it could be a bad switch on the handle. If the unit still wont turn on I would think that maybe the low voltage wire got disconnected from the unit or there is a break in the low voltage wire somewhere along the way. Let me know if you plugging the hose in sideways works.

Nu-tone 475 keeps running even without hose plugged in.


If the central vacuum tank will not turn OFF even with the switch in the “OFF” position, then the low-voltage wires should be disconnected from the tank. Once this is done, if the tank continues to run and cannot be turned off with the switch, then most likely the relay inside is defective and needs to be replaced (but it could be a defective and/or shorted ON/OFF switch). If with the low-voltage wires disconnected at the vacuum tank, it can be turned off with the internal switch, then either there is a short in the low-voltage wires, or else there is a hose still plugged into an inlet somewhere. ~ TTURAMBAR

It is possible that the low voltage wiring that controls your central vacuum has been damaged during the cable work. You can check to see if the low voltage relay is working by shorting the two terminals together at the unit. Just disconnect the two small (18-22 gauge) wires from the unit and short across the terminals where the wires connect. If the unit comes on, the vacuum is fine, and it is most likely the low voltage control wires that have been damaged. It should be a pretty easy fix, if you can get to where the wires are located. They are probably just pulled apart at a joint. Good Luck!!

Carpet Beater for Central Vac


Some of these types of hoses, if there is a male plug on the end that goes into the wall outlet, could be that one side of it is fused and will have to be replaced. When something happens like a short or a bad brush roll stall, this fuse will open up. If you supplied the model number I may habe been able to look it up and see. But if the hose end cuff comes off, then you can check it with an ohm meter to see if one side is open or not.

There is two possible causes. One you could be plugging in the end of the hose wrong. Make sure the hose end is securely in and in the right position. Second it could be a malfunctioning switch in your handle. Here is a site with a variety of different hose handle switches.

Central vac (Hoover) always on!


There should be a manual/auto switch. If it is in the manual mode, then it will run all the time. Other then that you probably have a stuck relay. But this will have a years warranty on it, so you should be able to have it serviced under warranty.
