The most likely cause is incorrect wiring to your wall valve inlets. Disengage one of the system wires on the front of your power unit and if the system shuts down then you need to verify the wiring to your wall valve inlets is correct. If the problem persists call Broan-NuTone Technical Support at 888-336-6151.
NuTone® PurePower™ Series Central Vacuums combine powerful suction and unmatched filtration, to remove dust and other allergens from your home. Central vacuums exhaust the vacuumed air outside of your home unlike a traditional vacuum that recirculates air back into your living area.
While different factors affect how long a system lasts, many central vacuums can last 20-30 years, or even longer, depending on how often they are used.
Check that the vacuum cleaner is plugged into a working power outlet and that fuses and breakers don`t need resetting. An activated thermal cut-out due to a blockage is the next most likely cause of the problem. Check for blockages in the hose and filters, and remove any obstructions that you find.
the vacuum system may be dirty, the pumping line may be restricted or too small in diameter, the pump may be dirty or with too little capacity, the pumping speed may be restricted due to other causes.
If there is no or low suction, then the clog is in the hose. You can remove the clog by running a long, stiff object through the hose, such as a butter knife, starting at the wall end. Another option would be to reverse the airflow through the hose by connecting the handle end into the intake on the main unit.

FACT -The components that are in a NUTONE central vacuum are no longer manufactured and built in America – NUTONE`S are now equipped with China made motors, and relays. In fact, 100% of all NUTONE motors today are not made in America any longer.
The company was founded in 1936 by J. Ralph Corbett in Cincinnati, Ohio.
Can you reuse vacuum seal bags? The quick answer is yes, especially if you`re using vacuum sealer rolls.
A full vacuum bag can also cause the motor to overheat and eventually fail, resulting in costly repair expenses or the replacement of a new vacuum. If you are using an upright vac with a belt-driven system, a full bag will increase the amount of force required to spin the brushroll, which can damage the belt.
Neglect your vacuum filter bags, and you`ll swiftly lose suction power. This, in turn, places unnecessary strain on your vacuum`s motor. Eventually, your vacuum will become a lot more difficult to maneuver, not to mention less effective at cleaning your rugs, carpeting, or other surfaces.
If you don`t vacuum your carpet, the dirt will break down carpet fibers and create a breeding ground for dust mites and bacteria. In addition, your home will begin to smell musty from the dirt, mites, and other organisms settling into the fibers.
Yes! Although they are relatively low maintenance, central vacuums require some regular upkeep to keep running smoothly. The two main types of in-home central vacuum systems are filtered and cyclonic. They require slightly different upkeep methods.
Power Usage

The amount of power used by a central vacuum system is roughly the same as that of a portable vacuum cleaner. Yet, it has 3 to 5 times the power of a portable vacuum cleaner. You are getting more suction power, which translates into more efficient cleaning, at no extra energy usage.

There are varying degrees of quality and value when it comes to vacuums; if you paid a lot for the appliance, repairs are likely worth it, but we recommend that you don`t spend more than half of the original price for any repairs.
A strong odor from the shellac that coats the copper coil windings is an indicator that the motor is about to or has burnt out. If the motor is still running, even if it turns on and off by itself as it is heating and cooling, you can still run the motor until it gives up for good.
Although you should leave some vacuum pump repair to an expert, there are things you can do to diagnose and fix faults in the equipment. A vacuum pump repair facility may offer services to train you internal maintenance men to do various levels of pump repairs.
Our central vacuum filters are essential parts of the system, keeping your motor clean and running well, while also filtering dust and other debris out of your environment. Try a CentralVac system and discover the difference we can make.
Central vacuums can be equipped with either an electrical power brush or an air-driven power brush. The air-driven (or turbine) systems are frequently less expensive since they do not require electrical wires for power to be run to each wall inlet.

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
ANSWER : 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.

Electrolux Epic 6500SR Full Bag sensor working, Does not Reset properly
ANSWER : The problem was a sticking switch that was not being reset. The vacuum on/off switch mechanism is comprised of two switches. One is the main switch that turns the vacuum on and off. The second is a shut off switch that gets tripped when the full bag sensor is engaged. This second switch is supposed to get reset when you push the on/off switch on the outside of the machine. The full bag shutoff switch was stiff and it, therefore, was taking a couple of presses of the on/off switch to move the shutoff switch back into the running position.

Unbeknownst to me, someone took the bag out of my Kenmore Progressive vacuum and failed to replace it. I have been vacuuming without a bag for months, and today the vacuum stopped sucking. When I opened up the front to replace the bag, tons of dirt and dust came pouring out. I thoroughly cleaned the vacuum, put in a new bag, but still no sucking power. Just dust coming from the rear vents where one of the filters is. Is the vacuum ruined, or is it a simple solution of buying a new filter?
ANSWER : Sounds like you need to buy a new motor. All that grit and dust will ruin a motor and I’m surprised it lasted as long as it did.
.This is where a vacuum that won’t run without a bag would have been nice. (Aerus for one)

While vacuuming the red light for the bag of the vacuum came on and the vacuum stopped. The bag was no where near full so I replaced it with a new bag – same problem. It vaccumes for a minute or then stops with bag light on. It is the correct bag for the machine – so what’s the problem?
ANSWER : I’m assuming this is the Epic 6500 or similar model.
.Detach the hose, turn vacuum on. If it runs, place palm of hand against inport hole. If it shuts off the problem is with either the control valve setting or the control valve assembly itself.
.For cvs, turn dial on top of vacuum all the way to the largest dot, and try above test again. If that doesn’t work, then it’s the CVA. It needs to be cleaned or replaced, which is an in shop job. Fro repair, take it to the nearest Aerus Electrolux store. I recommend a full clean and service to remove any dust/dirt from the motor, fan assembly, and other internal parts.
.
.Another problem, which relates to the dial setting, is that fine dust will quickly clog the pores of the bag, resulting in the machine “thinking” the bag is full. Turning the dial to the proper setting helps get the bag fuller. The middle setting is the normal setting, and is for areas without fine dust and sand.

Dirt devil vacuum cleaner–trouble vacuuming dirt and pet hair on carpeting –is the problem with the spinning brush which contacts the floor,  not contacting the carpeting??  I thought (when I bought this vacuum) that the aforementioned brush was adjustable to various heights of carpeting.  Sometimes, it seems like nothing is being vacuumed up –unless I have just put a new bag on the vacuum… Do I need or can I replace the spinning brush on the bottom of the vacuum so it kicks up and vacuums
ANSWER : Try replacing the belt. Rubber belts stretch out after about a year.

Won’t start. My son was using the vacuum & Didn’t change the bag. The vacuum was making the full bag smell, but the light was’t on & it didn’t stop. I stopped him, changed the bag, checked the filter, closed the compartments & turned on the vacuum. Nothing happened. I checked to be sure that it was plugged in, that wasn’t the problem. I’ve let the vacuum “rest” for several days, It still won’t start. Any suggestions?
ANSWER : There is a reset button at the back of the powerhead. The user manual can be downloaded from the electrolux website, although I didn’t find it very useful. There was some info on how to change the powerhead drive belt.

I purchased a brand new Eureka Pet vacuum, sorry don’t know exact name but it the one that has the self cleaning duster on it. Last night I used the vacuum on my carpet, it was working fine until I accidently sucked up the corner of a scarf that was hanging off a couch. I shut the vacuum off, pulled out the scarf and and resumed vacuuming. Much to my dismay the suction on the vacuum had ceased. Can you tell me if there is a reset button on the vacuum? The vacuum does not appear to be damage
ANSWER : If the motor is running, there should be suction. Possible problems depend on whether it’s a canister or upright and are:
.A clog in the hose, UR or canister. Detach hose. Drop small coin in one end and lift hose causing it to roll out the other. If it does, no clog in hose. Drop same coin into hose opening on power head. If it rolls out, no clog in PN.
.Broken fan blades, UR. Needs to be taken to shop for repair/replacement.
.
.A reset button is for use if the motor isn’t running, so won’t have anything to do with the suction.
