Question about Vacuums

1 Answer

I have a central vacuum system. When I disconnect the hose from a wall outlet the central canister does not shut down dispite my turning off the vacuum at the handle of the hose. The only way I can get the system to shut down is to pull the plug at the canister. What gives? Rob

What I'm hearing is the canister(Not the Powerhead) portion of the unit is running all the time unless you unplug it. this problem could be caused by a short in one of your low voltage lines running through the house. To determine that just unplug one/both low voltage lines from the canister, and plug it back into the recepticle. If it doesn't start up then you figured out that it is in the house somewhere and not the unit. If it is in the house I would check for water in the valves, or you're just gonna have to chase down the short. If the unit is still running with the low voltage wires disconnected then it is probably the relay on the board, which means you will need a new board unless you're expereinced at soldering and want give it a try replacing just the relay. Which you'll probably need a new board by the time you're done anyhow. LOL

Good Luck

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.

It sounds like you may have a bad hose. Plug the hose into the wall but rotate it 90 degrees from the normal position. This will bypass the switch on the hose. If you look at the wall end of your hose, you will see a metal band around it. That metal band is split into two sections. You are trying to plug in the hose so that the separation of the two pieces of metal is not lining up at the top of your inlet. If your vacuum turns on then you have a bad hose. It is possible that you have a bad switch in the hose, but it is more likely that you have a bad hose.

If your vacuum does not turn on, then you may have a break in your low voltage wire somewhere. You can check to make sure it didn't get disconnected at the unit. If the wire is connected then try to cross the low voltage wire from the relay at the unit with a small screw driver. If the unit does not turn on you have a bad relay.

If it is the relay, AirVac does not provide them. You would need to consider buying a new unit.

If it's just the one outlet, then there's probably a clog in the pipe between that outlet and the main pipe. You may be able to clear it by plugging the hose into a working outlet, placing other end to non-working outlet, and turning vacuum on. This may provide enough suction to **** out the clog.
If not, you'll probably need to use a mini plumber's snake to try to remove it.

If there is a switch on your hose, it may be broken.
Your system powers on from the inlets via two low voltage wires that run from the inlets to the switch/relay at the power unit. Each inlet has 2 spring loaded pins attached to the low voltage wires. In the photo below you should see these pins at the bottom of the opening, just above the door hinge. The receptacle at the top of the inlet in this photo supplies 110 volts to power your power nozzle. Not all inlets have this option, but if yours does, exercise extreme caution. Your hose must have a completely metal end or if it is a plastic end, it must have a metal band in order to short the 2 low voltage wires together to trigger the switch.
You can manually short the two low voltage pins together by using a metal pipe or needle nose pliers, just touch both pins at the same time. CAUTION: stay away from the 110 volt receptacle if present.
If your system powers on with this manual method then it would seem that the problem is in your hose.
If your system does not power on; your low voltage wires may be disconnected from the power unit or disconnected somewhere else . It's also possible that you have a bad circuit/controller board in the power unit.

A Nutone CV-450 System with inlet nozzle switch issues


You are suffering a connection problem of the hose end fitting to the wall outlet. Either the hose is not aligned with the two pins in the wall outlet, or the pins in the outlet are dirty and not making good connection to the hose end fittting.

My nutone vacuum system won't shut off when I pull the hose out of the wall...any thoughts


The relay that turns the machine off from any of the several places where you connect, is probably stuck.

The relay is operated by low voltage. When you connect your hose, you comlete the low voltage circuit and energize the 110 volt system, and the machine comes on. When you pull the hose out, the relay is suppose to release.

those are my thoughts

I hope this is of value to you.

Central Vac will not turn on.


These problems are nearly exclusively caused by a bad circut board and replacing it is the fix. Bad boards can cause many different effects so its nearly impossible to be sure. The 9v signal wire is not enough to short out an entire unit so it is unlikely the hose. If it is a direct connect system and you are pulling power from the 110 somehow that would cause main unit problems but that is unlikely at best. Sounds like a failed board to me.

Best of 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

I have a 3 year old NuTone CV 353W central vac system and recently the switch on the hose handle does not turn the system on from any outlet in the house. I have to plug the hose into the outlet and then turn the unit on from the switch on the canister. Any help would be greatly appreciated. Thanks

Hello,
I would advise you to ALWAYS to FIRST UNPLUG YOUR VACUUM before beginning any service procedure. There are a couple of things that come to mind, 1st. you may have a bad switch in the hose and in most cases that can be repaired – if not you would have to purchase a new vacuum hose. 2nd. You may have a bad inlet valve in your hose and most of them are low volt of which would only cost less than $10.00 and can be replaced yourself unless you have what they call a SuperValve of which has 2 low volt wires and then it is wired to your home electricity and that should be replaced by an licensed electrician. It is a low volt and high volt inlet.

#3. the last thing you may check id that you may have a bad relay in the canister itself. Because you should be able to turn on the Central Vac with the switch on the hose and everything should work just fine . feel free to contact your local vacuum cleaner dealer in your area of call the Nutone Factory cust serv line for further assistance. 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.
