How to Identify and Fix Common Vacuum Problems ?

Our sources include academic articles, blog posts, and personal essays from experienced Vacuum Technicians :

When using the central vacuum system, you simply plug a hose into one of the inlet valves. The hose connects to the power unit, creating a powerful suction that pulls dirt, dust and debris through the tubing system and into a collection canister.
If the unit runs for a few minutes then shuts off, the motor needs to be replaced. Central vacuum motors generally last for 800-1100 working hours. If your motor has run less than 800 hours or activates by jolting the canister, it may be possible to extend the life of the motor by replacing the carbon motor brushes.
Why won`t my power unit shut off? Make sure the unit is in the Auto mode and that there is not a hose plugged into a wall valve. Unplug the low volt wire at the side of the unit, if the unit continues to run, the relay in the pc board is faulty and the entire pc board needs to be replaced.
As a central vacuum manufacturer we use the 120 and 240 volt motors. The 120 and 240 motors will not be adversely affected if used with lower voltages. The 120 volt motor will be fine on 110 volts. Likewise, a 240 volt motor will be fine on 220 or 230 volts.
The Low Voltage System consists of a small wire that follows the pipe from the inlets all the way to the Power Unit. Similar to a doorbell, closing the circuit activates the device on the opposite end. The inlet valves have two small contact points inside that mate with the hose.
Central vacuum systems are designed to remove all the dirt and debris from your house and send it through tubing located in the walls to a receptacle in an out-of-the-way location like a garage or basement. With central vacuums, you only carry a lightweight hose and power brush unit around the house.
Overheated Motor

If your vacuum was working fine and then suddenly shut off, it may have overheated. Most vacuums are equipped with a thermal protector safety switch that won`t allow the motor to run when it becomes overheated. You will need to wait for 30 minutes to 2 hours, depending on your machine, to try again.

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.
Plug the power cord into your power source. Now arc a wire across the low voltage terminals. You should see a little spark when you touch the terminals and you should hear a “click” inside the board. If there is no spark, then the transformer is bad.
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.

Most vacuums have a motor amp rating of 12, but sometimes this number can dip to 11 or 10.
Most vacuum machines are equipped with motors that use anything from 500 to 3000 watts of electricity, with the typical unit using around 1,400 watts.
Low voltage is traditionally ran to every inlet in order to switch the suction on/off. The cover plate that fits into the mounting plate has two screws where the low voltage wires are connected. Through either the hose being inserted into the cover plate or a hose handle switch the suction turns on.
ln order to operate the central vacuum power unit remotely from inside your home you would need to complete the low-voltage 24v dc wiring.
Vacuum technology is the use of vacuum or high-vacuum for optimum insulation of transfer lines or systems. A thin vacuum environment is created inside the pipe or system by constructing these with a double wall and extracting all the air between these walls with vacuum pumps.
Central vacuum without a bag

A central vacuum that does not use a bag, has other perks just as attractive. First, the cyclonic suction assures a constant suction power while preventing the motor from overworking. Also, saving on dust bags is significant and eco-friendly!

Rather than waiting for the canister to fill up all the way, the Vacuum Experts suggest you empty it after every use. If that`s not feasible, “empty the vacuum once it reaches half to two-thirds of the way full as a matter of habit,” the Vacuum Experts blog post recommends.
Depending on how often you use the appliance, central vacuum canisters need emptying every three to six months, but you may need to check it more frequently. The first thing you should do when you notice that your vacuum is losing suction is to check the canister and filter.
Vacuum cleaners come with various foam or mesh filters. These might get clogged over time if not cleaned or replaced properly. This will cause your vacuum to lose suction. For general outlines about how to take care of your vacuum cleaner filters, see here.
Low suction or poor pick-up may be due to a clog in the vacuum cleaner. If you notice a change in the sound of the motor or a reduction in the spinning action, check for clogs. First, remove the Easy Empty dirt tank from the vacuum and discard all dirt and debris.
Typically, they have about three to five times more suction power than conventional vacuum units. You don`t have to drag the main vacuuming unit around with you. The most you`d have to carry with a central vacuum is a hose and a few light accessories. Central vacuums make for healthier indoor air quality.
If all you hear from the vacuum unit is a click at the when you try to start the vacuum motor from inside the house, then the motor in the unit is dead and has to be replaced. A strong odor from the shellac, which coats the copper coil windings, is an indicator that the motor is about to or has burnt out.
The suction power is to be measured at the end of the tube of a complete vacuum cleaner (i.e. with tube, hose and filters – but without nozzle). Some manufacturers show the results from measurements made at the suction of the actual vacuum cleaner.
Putting in the incorrect amount of oil, putting in the wrong type of oil, and oil contamination can all cause the pump to not reach full vacuum. For this reason, you must check the oil regularly to ensure that it is not only clean, but also properly filled.

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.

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.

Miele Champagne Vacuum Cleaner Model S548 I was using the vacuum as normal, moved locations so I plugged into another outlet & suddenly there was no power to the vacuum! I tried it in several other outlets, tried the reset button… & still no power to the vacuum. Any ideas what could be causing this? Any info would be greatly appreciated. Thank you!
ANSWER : Greetings from ,

.This definitely sound like a cord reel issue to me. This is really the only problem that I ever see on a Miele vacuum cleaner. 9 times out of 10 the cord reel needs to be changed. If you purchase the cord from us, and it’s not the problem you may return it up to 60 days later for a full refund, that’s how confident I am that is what’s wrong with your machine.
.
Ok, so you need to replace the cord reel on a Miele , no problem! I’ll attempt to try and walk you through this repair with a detailed explanation of it, and along with some pictures to help you. You’ll first want to buy the new Miele S500 series cord reel

So once you have the cord reel, you’ll need either a Phillips head screw driver for the older S514 models, or a T20 Torx Screwdriver for the newer S514 model vacuums. The picture below is actually of the Miele S518 Cat & Dog series, but for this repair the procedure and parts are identical to your Miele Champagne. You’ll need to remove the hose, wand, and power nozzle from the vacuum cleaner before you begin.

The first thing you’ll wand to do is open up the bag housing, and remove the vacuum bag, as well as the exhaust filter which may be either the Cloth Super Air Clean Filter, or the HEPA Filter catridge which is blue in color. If you’re using the Super Air Clean filter, remove the filter, and then remove the bracket that secures the filter in place as well. Simply pull straight up on the bracket and it will come out.

Once the bag and the filter have been removed, you’ll need to take off the entire tool lid. While the vacuum cleaner is open so that you can see into the compartment where the bag just was, you need to pry two arms from the tool lid off of the main body housing. Simply put a screwdriver behind one of the blue arms, and pry inwards. Here’s a picture of what this looks like;

ea76cca.jpg
Once you have removed both of these clasps, the tool lid will pull straight upwards and off, leaving you with only the bottom part of the canister. This is how the vacuum cleaner should look now;

4e90a53.jpg
Now you’ll need to remove the black speed control box from the canister. There is one screw in the front of the black speed control box that needs to be removed. After the screw has been removed, turn the vacuum cleaner around so that the back of the machine where the cord reel goes into the vacuum is now facing you. If you look where the black speed control box meets the bottom part of the canister, you can see two clips that you’ll need to release before the variable speed control box can be removed. Simply put a screw driver and push in on the clip while lifting the black speed control box at the same time. Here’s where the clips are located on the vacuum;

c4f57b8.jpg
Ok, now that the speed control box has been removed, it’s time to separate the colored plastic from the base of the vacuum cleaner. There are 7 screws that need to be removed in order to get these housings separated. I have circled the location of each screw in the picture below;

d7e09aa.jpg
After removing all 7 screws, you can then simply pull upwards on the colored plastic housing, and remove the housing from the base of the vacuum cleaner so that the motor and cord reel are exposed. Once you have exposed the cord reel, you’ll need to remove the internal wires (white wire is in the higher posistion, and to the left of the lower right side black wire), as well as the rubber hose part. The rubber hose part simply pulls off, just like the wire terminals do. After removing these parts, you’ll need to remove one more screw with your screw driver. Here’s the picture of which screw needs to be removed;

707ba1e.jpg
After the final screw has been removed, you’ll have to remove the rectangular shaped wire harness that sits at the top of the cord reel. Pay close attention to how this wire harness is correctly seated which will save some aggravation when putting the vacuum back together. Here’s a picture of the wire harness that needs to be removed from the old cord reel;

9dd734e.jpg
Once the wire harness has been completely removed from the old cord reel, you may simply pull up on the cord reel and remove it. The new cord reel will come completely assembled, with all the parts and compontents that your faulty cord reel had. You simply need to line up the screw hole on the new cord reel with the hole in the bottom of the base of the vacuum. When installing the new cord reel be very careful that you don’t pinch any of the wires down by putting the cord reel on top of them. The wires have a specific place they go, and you’ll be able to see the correct path for these wires when paying close attention. Also remember to install the rubber tube back onto the new cord reel as well. Once the new cord reel has been installed, and screwed down, pull the plug out a little ways, and guide the plug through the colored top housing first, then screw the 7 screws that hold the upper housing to the lower housing back into to secure these housings together.

That’s about all there is to that repair! Please feel free to request a repair clarification if you have any questions about the repair that I can help you with, I’m always more then happy to help.

I have a Eureka Boss Power Plus and the beater bar is rolling, the belt is turning, but after vacuuming up around the litter box (not a lot of litter), when I turn the vacuum off, the litter, or even household dirt, falls out. When I hold the vacuum back to turn it off so that it doesn’t fall on the floor, it’s sitting in the cubby where the wheels are. The bag is empty, the hose is not plugged, the hose is securely fitted on both ends of the unit. This vacuum was purchased in July and is being
ANSWER : Even though the brush is spinning, you probably need to replace the belt2_bing.gif because it is stretched. It is probably slipping on the beater bar. This is normal and you shouldn’t be alarmed. There is nothing wrong with your vacuum. 🙂
