Question about Tristar Vacuums

Open Question

TriStar vacuum cleaner sounds normal but has no suction.

New bag, clean filters, no clogs in hose. It's 20 year old. Is the motor shot? Thought the motor would sound different if it was bad. Help! My carpet is filthy!

    Problem solved! Took apart the canister and found the motor was loose from the rubber gasket that held it in place. Re-attached it and put the canister back together and voila'! Suction again! Thank you, anyway, fixya friends!

Check to make sure that your agitator still spins. (Agitator = brush). If your agitator still spins, it eliminates your belt and agitator as likely culprits. The last possible solution would be that your vacuum is clogged. The grinding sound might be a motor-related issue or could possibly mean your bearings are going out. Check the bearings of the agitator and the motor of the vacuum.

Accessing to the agitator and belt can be done by removing the bottom cover of your vacuum. There are 2 scews that are holding the bottom cover to the head of the unit. Remove these 2 scews and the bottom cover should snap off.

SOURCE: Bosch Vacuum Cleaner: I changed

Greetings from GoVacuum.com,

It sounds like you may have a bad thermal switch inside the machine. Most vacuum cleaners have a switch connected to the motor, so if the vacuum cleaner is running hot, it will shut off to prevent any damage to your motor. You did all the right things by checking the bag, making sure the hose was NOT clogged, and replacing HEPA filter.

Most of the time on canister vacuums, the reason is caused by a clog in the hose, or somewhere in the powerhead. If you're sure that there is no clog anywhere, it is going to be the thermal switch on the motor.

Here's a link to the parts schematic for the Bosch upright vacuum. I hope it helps you in determining how to access the thermal switch. A word of warning to you before you try it, this is a very tough vacuum cleaner to work on, you may want to bring it in to a vacuum repair shop, as this is not an easy repair.

Here's the link;

SOURCE: suction problem

check the intake hose at the bottom it may be clogged.try blowing into the long hose if you can't blow through it then you have a clog somewhere between the long hose and your intake hose at the bottom.the intake hose is the somewhat clear hose that comes up from behind the base at the bottom.you will see it on the backside

My Miele S3141 canister began acting strange this morning. No suction...so I took off the hose and checked for blockage, (nothing). Now I can't get the hose back on the canister. It just slips ar


see this causes and fix it. God bless you
Air filter:
If the vacuum cleaner won't pick up dirt and has no suction the air filter might be clogged. Remove the filter and either clean or replace it as needed.
Exhaust Filter If the vacuum cleaner won't pick up and has no suction the exhaust filter might be clogged. Remove and clean the filter, replace it if its torn or damaged.


Vacuum Hose If the vacuum cleaner won't pick up and has no suction the vacuum hose might be clogged. Remove the hose from the vacuum cleaner, stretch it out straight, shine a bright flashlight in one end and try to see light through it. If no light can be seen, use something to run through the hose and free up the obstruction.
Vacuum Bag If the vacuum cleaner won't pick up and has no suction the vacuum bag might be full. Clean or replace the bag as recommended by the manufacturer.

Dust Cup AssemblyIf the vacuum cleaner won't pick up and has no suction the dust cup assembly might not be installed tightly, or it might be cracked or broken. The dust cup must seal tightly in order to produce the right amount of suction. If it is cracked or broken, replace it. Most glues and adhesives will not successfully seal the crack.
Blower Wheel If the vacuum cleaner won't pick up and there is no suction, the blower wheel might be jammed or broken. Check the blower wheel to be certain it turns freely. If it doesn't, check to see if there is anything rubbing against it. If not, but it's hard to turn, the motor is most likely the problem.

Loss of suction o=with hose tool


Hose or tool is probably clogged. Is this an upright? Bagged or bagless? Have you changed the bag and filters? Cleaned out the brush and hose that goes from the brush area to the collection bag/cup? The only reason for a vacuum cleaner to lose suction but still work is a clog or dirty filter which blocks the air flow. Follow the air flow from the brushes to the bag/dirt cup. If the machine is bagged, change the bag. I use another vacuum cleaner to do this.While your at it, might as well change the belt.

There are six different reasons a vacuum can lose suction, a plugged vacuum hose, bad motor, full vacuum bag, or cracked or damage hoses. Purchasing a vacuum cleaner can be a costly expense while repairing the suction on the unit can be virtually free. Most suction loss problems on a vacuum can be easily fixed or remedied with common house hold tools and very little technical expertise.
If your vacuum cleaner losses suction, the first and easiest solution is to check the bag. If the vacuum cleaner bag is full suction will be greatly reduced and the unit will become ineffective. A vacuum cleaner works by passing air through the bag fibers leaving dirt and debris behind inside the bag. If the refuse bag becomes full, airflow is restricted, limiting the amount of air passing through the vacuum bag resulting in loss of suction. When replacing the vacuum bag always consult your owners manual to insure that the vacuum bag seals with the vacuum inlet hose. If your vacuum cleaner bag is not tightly sealed to the vacuum inlet hose you will decrease the air flow through the bag resulting in loss of suction.
The second and sometimes most common reason for loss of suction on a vacuum cleaner is a plugged vacuum hose. If the hose becomes plugged, air flow will become restricted. To unplug a vacuum hose detach it from the machine and inspect the inside. If there is a restriction in the hose, remove it with your fingers and replace the hose onto the unit. If the hose is long and the debris is hard to get too, a broom handle or other long object can be passed through the hose to dislodge the debris. Most vacuum cleaners contain more that one suction hose, so make sure to check each one by process of elimination. Another area that can become easily plugged on a vacuum cleaner is under the lower base of the unit by the roller brush. Large debris can get caught in this area and restrict air flow to the hose.
If your vacuum refuse bag is not full and the suction hoses are not plugged the next thing to check is the condition of the hoses. Many hoses are made from plastic which can easily tear or crack. If your vacuum cleaner shows signs of wear or are cracked they need to be replaced. Even the smallest hole in a vacuum hose can leak enough air to greatly diminish the suction potential of your unit. Replace your vacuum cleaner parts with OEM parts from the original manufacturer to ensure the tightest fit.
Most vacuum cleaners contain filters. Filters are used as a last line of defense to remove dust and smaller debris particles before the air is recycled back into the environment. If vacuum cleaner filters become dirty or plugged they also can decrease the amount of air traveling through the unit. Some filters can be easily rinsed with water whereas others need to be replaced. It is important to check your owners manual before rinsing a vacuum filter.
The last and probably least common problem for a vacuum cleaner to loose suction is a bad or failing vacuum motor. Over time vacuum motors lose power due to worn carbon brushes or long term damage. A vacuum cleaners worst enemy is moisture. If water or moisture is sucked into the vacuum motor it will greatly diminish the amount of suction the unit has. Replacing a vac motor can be a costly and time consuming ordeal. In some cases, replacing a vacuum motor can outweigh the cost of buying a new vacuum. Vacuum suction is measured in water lift which can easily be measured by using a water lift gauge. If the water lift measured in inches, falls below half the original water lift specifications for the unit, it is time to replace your motor. Most vacuum cleaner repair shops carry this type of equipment and can easily tell you if it is time for a new vac motor.

I have a Eureka 4800 series the Boss upright with a bag and Hepa filter. I love it! I was just vacuuming with the hose part and all was well and then suddenly the lower brush came on and a "burning" smell...


I had the same problem. Take out the old belt if possible. Remove the 4 screws inside the filter and the 3 on the front of that housing. pull out the foam around the motor. carefully pull out the suction tube that is press fit against the motor. then you can pull the motor out. place it on its side, shaft side up and grab your hammer. tap down the metal sleeve that has been rubbing against the plastic housing. reinstall everything including a new belt and you should be good to go.

After we change the bag, it still gives us a red light


Greetings,

The bag full indicator on most vacuum cleaners is not completley fool proof. Most vacuums will just register a loss of suction, and they will then illuminate the bag full indicator, whether or not the bag is full.

If you've changed the bag, and the machine is still indicating a full bag, then this could mean one of two things.

1. Dirty Filter. According to the part diagram for your vacuum, there is a filter underneath of the vacuum cleaner bag (Bissell Part Number
203-1013) that is there to protect anything from getting into the motor. Since the filter is located before the motor, most refer to this as a pre-motor filter. Sometimes if this filter is really dirty, it can cause the vacuum to loose suction, which will also cause the bag full indicator to incorrectly display. Simply clean this filter by running it under warm water, then allow it to completely dry before replacing it in the vacuum. While the filter is out of the vacuum you can turn it back on and test to see if the light is off now that the filter is out. If the light goes off, then you have found the problem! If the bag full indicator is still on, please see the next possible problem.

2. Clog In the Vacuum. If the vacuum was run with a full bag, and when you removed the bag, the bag was completely jammed full, then your vacuum cleaner may be clogged somewhere. When the bag is packed full of dirt, the vacuum continues to try and put more and more dirt in the bag, even if it's full. Sometimes the dirt will even start accumulating inside the hose as it has no other place to go. The first place you should check is the hole that you connect the bag to. Remove the new bag that you installed and examine the hole that the bag connects to inside the vacuum. Can you see anything stuck here? If yes, do your best to try and dislodge it. If you're not able to visibly see anything here, your clog may be inside the hose, or even in the base of the vacuum.

If you have another vacuum cleaner this will really help you in clearing the clog. With the other vacuum, take the suction hose of the good vacuum, and connect it to the hose on your Bissell (still while the bag is removed, and the bag housing door is open). When you connect the hose of the other vacuum, can you hear a difference in the motor? Does the motor start running at a higher pitch when it's connected to your Bissell? If yes, then you've narrowed it down to a clog in your hose. If you can feel suction from the other vacuum through the hole that the bag connects onto, and the good vacuum's motor doesn't change noise when connected to the Bissell, then your clog is in the bottom section of the vacuum. You can sometimes stretch out the hose of the Bissell while the other vacuum is attached, and this will dislodge the clog.

If you don't have another vacuum, simply remove the hose from the Bissell completely. I believe that there maybe 2 screws that hold this hose onto the back of your Bissell, simply remove these two screws, and remove the hose. An easy way you can clear clogs is to take the hose outside, and use a water hose that has a pressurized nozzle on it, and spray down the hose while holding the hose of your Bissell vertically to allow gravity to work its magic. You can also stretch out the hose of the Bissell to get maximum benefit of gravity and the water.

If the clog is in the lower part of the vacuum, it is usually right at the suction port behind the roller brush. This is the most narrow part of the vacuums suction intake in the lower part of the vacuum, and is prone to clogs. Simply remove the four screws on the bottom of your Bissell to remove the bottom plate. Look behind the roller brush to where the suction port is to see if you can see any clogged debris.

If this doesn't help clear your clog, or fix the bag full indicator, I'd really like to try and diagnosis this further with you. Please just use the Clarification Request or add a comment and explain what happend after trying these things I mentioned above. I'll be more then happy to try and assist your further. I really hope that this was helpful to you. If you found this helpful, please be kind and rate my repair by clicking the thumbs up icon in the review.

Thank you very much,

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...


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 :)

Filter being sucked into the motor


There is no way someone can hear what your vacuum is doing over the phone. Be cautious of anyone that tells you that.

If there is a clog anywhere in the lines either in the wall or the hoses it will have really high RPMs because there is no air movement slowing down the impellers. Clogs on these units are sometimes hard to clean out.

If you have a bagged unit, make sure to replace the bag. If you don't have bags then you probably need to clean out the filters and possibly replace them. I would recommend you use bags. You don't want dust and debris going into the unit's motor.

If you hear a loud grinding noise then it may be the fan or bearings in the motor. I technician could easily determine this with just a sound.

the unit should come off the wall fairly easily.

Hoover U5468-900 WindTunnel Supreme suction is suddenly poor


The other possibility is there is a blockage in the foot. these models have dual channel air flow (windtunnel) and become blocked when not cleaned depending on use. under the roller there is a cavity that can be removed for cleaning. a hot motor can be caused by poor air flow.
