How to Identify and Fix Common Vacuum Problems ?

Blocked Filters. If your vacuum motor appears to cut out when it`s warm for a few minutes before restarting, it may be due to the motor overheating. This may be caused by blocked filters. They can become clogged over time from a buildup of dust molecules, preventing less or no cool air to flow into the motor.
You either have a clog in the hose or wand (canisters) or behind the clog removal panel on the s7 uprights. If that doesn`t solve your problem, when was the last time you changed your bags and filters? The clog may be inside the powered nozzle, and they are very easy to disassemble, but this is rare.
Durability & Warranty – If you`re looking for a vacuum cleaner with durability and longevity, look no further than Miele. Miele vacuum cleaners are designed and tested to last for 20 years. Miele vacuum cleaners come with a 7-year warranty on the motor and a 1-year warranty on parts and labor.
If your vacuum cleaner keeps turning off, this could be due to the following reasons: Blockages – check the hose and head for any obstructions. Filter – always check your filters, if these are clogged this could be causing the vacuum cleaner to work harder and lose suction power.
What`s happening with your vacuum cleaner is that a clog has built up and debris being agitated by the roller is spitting out or stirring up dust without sucking it in.
Check the Rotator Brush and Wheels

Sometimes pieces of string or other objects get wrapped around your vacuum`s rotating brush or around the wheels of the vacuum. Unplug your vacuum. Turn it over and have a look at the wheels and brush. If you see any pieces of string or objects lodged there, remove them.

Overheating usually occurs because the dust bag has not been emptied, filter has not been cleaned or there is a blockage in the floor tool, wand or bent hand piece. If your vacuum shuts down unexpectedly, make sure you turn the vacuum off and unplug it from the wall socket.
If there is something that has become caught in the hose in another part of the system, the airflow will be reduced and can cause overheating and a shut down. Clear out hoses, attachments, and brushes of any hair, dirt, and debris. This will allow for restored airflow and should get things going again.
The filters are clogged

These will find their way into all parts of the vacuum cleaner and clog up the filters, preventing them from working properly. This will also have an impact on the motor`s ability to cool, making it operate less efficiently and possibly causing it to overheat and produce a burning smell.

Miele Washing Machines are vigorously tested to last the equivalent of 20 years use. Miele Washing Machines are ecological and consume only the amount of water and electricity needed for excellent cleaning and rinsing results.
Are all Miele Vacuums Made in Germany? Miele vacuums are made at their Bielefeld plant in Germany, the second largest and second oldest factory of the Miele group`s 11 manufacturing sites in Europe. Motors for the Miele merchandise range are supplied and made from their plant 230km away in Euskirchen.
The most common problems found in vacuum cleaners are low suction force, excessive noise, burning smell, vacuum not turn on, and overheating. These issues can be fixed by either cleaning the device or replacing some parts of the device. At times, it is best to seek a professional to fix the cleaner effectively.
You vacuum too quickly

Vacuuming slowly will allow your machine to suck up more dirt and dust, and ultimately get your rugs and carpets much cleaner. Slow vacuuming allows the brush to agitate the carpet properly and suck up the unclean bits that emerge.

If your vacuum doesn`t have a HEPA filter, it`s likely stirring up more dust than it`s capturing. With the wrong product, you`ll simply pull dust up from the carpet and send it flying through the air. This could be the cause of the dust build-up you`re seeing.
Second, can you vacuum too much? Believe it or not the answer is no. Now, if you vacuumed continually 24 hours a day, yes, that would be too much. Vacuuming every day, or even a few times a day, is not going to create any long term problems.
The two main indicators to determine vacuum power performance are water lift and airflow. The water lift is measured in mmH2O, mbar or kPa. It represents the suction force and is the reference parameter for vacuuming liquids and heavy materials. The airflow is measured in m3/h or in l/s.
All vacuum cleaners operate based on air flowing from the opening at the cleaning head or tool, through the vacuum cleaner and the bag and/or filter system and then out the exhaust port. This airflow is created by the vacuum motor, which also may be referred to as the suction motor.
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.
Problems can occur when overused or clogged filters cause the vacuum motor to overheat. This not only shortens the motor life but causes a loss of suction. In some cases, total motor burn out can occur.
The average life expectancy of a mid-range vacuum cleaner is about six years. You can fix or replace things like blocked filters, jammed brush rolls, frayed hoses, worn-out stick vac batteries and broken accessories yourself.
Taking this into account, if we reduce the temperature of the product, the less atmospheric pressure will be necessary for bringing the product to boiling point and, therefore, the higher vacuum percentage will be achieved.
Vacuum cleaners are often designed to turn themselves off if they hit a thermal cut-off point. Basically, if the machine is starting to overheat, there is an automatic system in place to prevent damage to your vacuum or other issues. The most common cause of overheating is blockage.
Watch for Overheating

You should wait for about an hour for your vacuum cleaner to cool down before switching it on again. This is a great indication that there may be something serious about to go wrong with your vacuum cleaner and it is time to take it in for service.

Burning smell can indicate motor damage

If you suspect that the motor is damaged, you should not continue to use the vacuum cleaner! The cause of motor damage is usually wear and tear or damage caused by prolonged improper use (e.g. overheating). In most cases, it is not worth repairing.

Miele s571 vacuum cleaner power surges up and down in strength every few seconds from startup.
ANSWER : I just repaired the same problem. It is not the motor. There is a defective capacitor in the regulator. Large grey capacitor should have a value of 0.22uF/275V. It was in my case just 85uF. Changed capaitor and it was OK.

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.

1cd8104.jpg
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.

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.

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.

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.

My 4 yr old Nilfisk vacuum cleaner has been working fine up until now. But suddenly, it has hardly any suction power and also, hot air seems to be coming out thru the vents on top and also thru the space that’s normally used for blowing air OUT….the outlet with the retractable cover located close to the part where the power cable comes out of and retracts into. I’ve checked the filter and the hose and they are not clogged…I have also put in a new bag. Not keen to buy another vacuum cleaner u
ANSWER : Hi there SmartAlec from Nelsonvacuums.com.au here.It sounds like a blockage of some kind. The best way to find it is to set the machine up for normal vacuuming and remove one component at a time until the suction returns. eg turn on and feel suction under floor head – not good? then remove the rod, then the hose.
Once at the machine on its own it gets a little triky as i don’t know which model you have. However if you have a bagged model remove all the filters and the bag and retest. There will be at least 2 filters, one before the motor and one after (maybe under the vacuum or right at the back). If it is a bagless model even though the filter may look clean it is probably blocked with very fine dust. If suction returns when the filter is removed then you need to buy a new filter. I am a nilfisk vacuum cleaner agent so i can supply a filter for you.
If this still doesnt help you are welcome to call me if you live in australia my contact details are on my website www.nelsonvacuums.com.au.
Hope this helps !.
Happy vacuuming 🙂

Suction problem I have a Hoover Widepath Fold Away, 12 amp motor vacuum cleaner and the problem I am having is every time I vacuum, the vacuum gets clogged up with carpet. I am probably only able to do one stroke then it gets clogged and I have to stop and unclog it or it spits it out on the carpet. This is very frustrating and I don’t get much vacuuming done. Please can you help me. Thank you. Gwen email is [email protected]

I have a Kenmore canister vacuum – model 25614506. Some time ago, I was not able to turn the vacuum off with the on/off switch, but could still use the vacuum. Turned if off/on by pulling the plug. The other day when I went to plug it in, I heard a pop. Now the sweeper runs but the vacuum cleaner does not **** – no air flow. What could be the problem. The cleaner is only 4 years old.
ANSWER : The motor has an inline fuse
