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.

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.
Try a ruling out a couple of things first before opening up the handle:
1) First lets make sure your outlet has power
a) can you plug anything else in and have it work?
b) is the vacuum plugged into a non-switched outlet?
c) will the vacuum work from a different outlet - in a different room?
2) Check the plug. Are the prongs loose? If so, you'll need to cut the
plug off, splice back the two wires (Black and White), then connect
to a new plug. You can get a new plug for $1-2.00 at any hardware
3) Time to open up the handle:
a) sometimes the wires connected to the switch can become loose
and fall off. if that is the case just reconnect by plugging them
back onto the switch. You may also consider using pliers to
compress the connector onto the switch terminal.
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.
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
If the hose is non-wired then you can fix this yourself. When you Plug the cuff into your wall inlet does the vacuum turn on automatically? If so then you should be able to trim the hose with no ill effects other than losing eight inches of cleaning area.
If the hose has a switch on it's handle that turns the vacuum on and off, you will probably need a technician to fix the hose. Some wired hoses even have High Voltage lines in them and should never be taken apart.
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
http://geeksquad.fixya.com/ThreadView.aspx?prdid=0&thid=567634 Generic problem for all Vacuums I have a 3 year posted by patfitz on May 03, 2008 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. http://nutone.com/Customer Service Nutone Inc. 9825 Kenwood Road Suite #301 Cincinnati, OH45242 Customer Service1-888-336-3948 Technical Support1-888-336-6151 Thanks, Don the Vac Man Go Ahead.

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.
