Re: Hoover Hush Series Central Vac won't turn on

If the low voltage wires are hooked up to it, then you probably have a stuck relay inside the cannister. It could also be the switch in the hose handle.

I installed the Hoover Wind Tunnel Central Vac in my new home. After connecting the wall outlets and successfully turning on the system from the hose control, I discovered there is lots of air flow t

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.

Hi! My central vacuum has worked perfectly until just a couple months ago. I went to plug the vacuum in and it didn't automatically start the suction. When I clicked the switch to the right on the...

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.

Hush - Insufficient suction

You need to approach this step by step. If you have insufficient suction at all locations you need to check as follows:
1. Hose, drop a coin through from the handle to the wall end, with the hose detached from the wall. If the coin goes through from one end to the other the hose should be clear. If the coin stops it will rattle inside where the obstruction is if you gently shake the hose you will feel it through the wall.Obstructions in hose or pie need to bee **** wards out of the hose or pipe.
2. Vac. Go to the vac itself and see if the onboard inlet has suction. If it does your problem is beyond the vac. If not your problem may be a leak, either a broken inlet, with a cracked or sagging door or jammed hinge, a clogged intake in the vac, or damage to the pipe within the house or a twisted gasket where the pail of the vac secures to the body, or an issue with the motor itself..
3. Take the hose, inlet to inlet and check all locations in the house. I mark a tissue with a number for each inlet and plug in the hose, one inlet at a time. If the tissue makes it all the way to the bucket from each location, that means the branch line for that location is clear. I work from the closest inlet away to the furthest checking for tissues one inlet a t a time. This will help pinpoint location of any blockage in the main line.
4. If you have had any renovations or painting done it is not uncommon to disturb the seal behind and inlet or pierce your piping with a nail or screw. Check for all these and post back to say waht you have found.

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 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.

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

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.
