Rainbow E series Canister Wet/Dry Vacuum\015 Hi. We have a rainbow e2 2 speed vacuum. Recently, our vacuum motor has been turning itself off after about 5 minutes of vacuuming our carpet or rug. The motor will turn back on for a few seconds if we switch the unit off and then back on. The vacuum will stay on for hours in the low speed but not in the vacuum speed. Any suggestions?\015

How to Identify and Fix Common Vacuum Problems ?

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

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.
A damaged vacuum hose, clogged motor air filter or bad suction motor can cause the vacuum cleaner to shut off during use. A tripped overload on the vacuum suction motor can shut off the vacuum cleaner during use. If your vacuum has a reset button, push it; if the vacuum seems hot, let it cool off first.
It is the only vacuum that is a certified air purifier and is designed to run 24/7 on a lower speed to purify the air in the home. The unique difference is the water. All dirt and dust is trapped in a basin of water so that no debris can re-enter the home atmosphere.
The water is the fluid which traps every dust and dirt particles that come into the Rainbow, Running your Rainbow without water allows all these particles pass into the Rainbow internal parts, and also clogging your HEPA filter, which is designed to be a backup filter to work together with the water.
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.
A vacuum cleaner can run continuously for 30 – 60 min each time. The vacuum cleaner has no suction power. For example, a hair cannot be sucked up.
If you find that your machine is turning off intermittently, the filter in your vacuum is most likely full and covering the ventilation system. Remove the filter, then empty and wash it. Allow the filter to dry for at least 24 hours, or until it is completely dry.
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.
With a high and low speed, you can run your Rainbow 24/7 to clean the air without disturbing your home in the process. The low speed is quiet and unnoticeable when standing right… The Rainbow water filtration is something you must see to believe. Once dust and dirt get wet, they can`t go back into the air.
For the best results, keep the whole home air purifier on all day. During common weather, you can run an air purifier for as long as you like. It`s generally a good idea to use the appliance only when someone is at home. An air purifier improves sleep quality by cleansing the air around you.
Vacuum up Liquids

Regular vacuum cleaners are not designed to pick up water and other liquids. If you are ever tempted to run the vacuum cleaner over a puddle of water, remember that you run the risk of electrocution and serious damage to the machine.

The Rainbow uses Mother Nature`s most powerful element, water, to trap dirt and odors, returning only naturally clean, water-washed air to your home environment.
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.
Generally overheating is caused by overworking the pump. If your vacuum pump isn`t working as it should, you`re having to run it for longer, or at higher speeds, making the pump overheat and potentially seize.
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.

Generally speaking, between the hours of 9 am and 7 pm, you`re pretty safe to vacuum. This will vary from place to place, and you should always consider the needs of your neighbors. Generally speaking, between the hours of 9 am and 7 pm, you`re pretty safe to vacuum.
If the filter bag or canister is too full, it cannot pick up any additional particles and will simply jam or the motor will overheat and shut down. So, when you suspect your unit is about 75 per cent full, empty it!
If you find that your machine is turning off intermittently, the filter in your vacuum is most likely full and covering the ventilation system. Remove the filter, then empty and wash it. Allow the filter to dry for at least 24 hours, or until it is completely dry.
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.
It`s possible there`s a power consumption issue, with there just not being enough residual charge to run the machine. A new battery should fix this. My other thought is that it`s overheating. If too much power is pushed through the motor, which MAX power does, it could stop after a few seconds if it become hot.

Rainbow e2 2 speed vacuum shuts off after 5 minutes of vacuuming.
ANSWER : 2 speed E2 models have a circuit board inside that controls the machine. It sounds like this controller board may be bad. The unfortunate part of this is that the board is not only very expensive, but it is only available from an authorized Rainbow service center.
. Use caution if you decide to work on this yourself or if you take it to a service center that is not famliar with these models. The circuit board mentioned above is susceptible to damage from static eclectricity discharge. The static you generate from just walking across a carpet could make this board useless. So, if the original problem is not the board you could make the problem worse.

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.

Bosch BSA2222UC canister vacuum shuts off after 5 minutes
ANSWER : I took apart the vacuum, removed the circuit board and cleaned the tiny bits of dust off it carefully, removed the cord winder (without letting it unwind) and carefully replaced both parts, blew dust out of the 2 armature brushes (lifted out the motor, removed the insulation wrap from around it and the 2 rubber gaskets first), then re-wrapped the insulation, replaced the motor, put it all back together making sure the switch was aligned properly, and ran it without the filters, hose, etc, until I was convinced it would stay on without impedance, then added one filter, then another, then the bag, then the hose and lastly the floor head. It never shut off so I think that small amount of dust on the circuit board was the problem. Hope this helps.

Rainbow E2 2 speed vacuum motor whines at startup
ANSWER : I used to sell rainbow vacuums and this latest 2 speed model does whine when it is first turned on. So you definately have nothing to worry about. I believe this is due to the fact that this motor is much more powerful than in the previous 1 speed E series model. I finally just purchased a 2 speed model after many many years of wanting one. Good luck to ya and enjoy your clean house!

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 HAVE A BRAND NEW HOOVER MACH-3 CYCLONIC THAT CUTS OFF EVERY FEW MINUTES. IT IS DRIVING ME CRAZY! IT’S LIKE AFTER 5 MINUTES OF VACUUMING IT HAS TO SIT FOR A LEAST AN HOUR THEN YOU CAN VACUUM FOR ANOTHER 5 MINUTES. HELP!
ANSWER : If it were mine and it was brand new I would bring it back and exchange it. It sounds like the motor is over heating and shutting off automatically. Does not sound good. My advice return it.

Infinity Vaccum by Shark, model number NV31COS, will not start. The vacuum was running just fine until it grabbed the edge of a curtain. Turned it off to release the suction. Turned it back on and was working fine. About a minute later the vacuum was making an odd noise. Every 2 seconds or so it would “heave” (lack of a better word) then go away, then come back and so on. Turned the vacuum off and checked for blockage, none that could be seen or felt, and now the vacuum won’t turn. Any suggestio
ANSWER : Carpet brush won’t turn when vac on

I purchased a Eureka C4910 last year and have a question that I am hoping you can answer.

There are two motor actions with this vacuum, 1) the vacuum suction, and 2) the beater bar. The action of the beater bar is that motor is supposed to automatically shut off when the handle is in the complete vertical position assuming the vacuum is stationary, but then turn on when the handle is tilted toward the floor, assuming the vacuum is moving back and forth.

The beater bar motor turn-on mechan

ANSWER : Good day!

Normally when the motor is easily moved back and forth means that it have a proper lubrication,proper alignment and no clogs.

When the motor and the belt is OK the problem could be on electrical wiring and switch.

If found electrical switch burned out you need to replaced it because when the switch is burn the contact of that switch is open even you turn it ON.that’s why the motor is not function because the voltage is not pass through the circuit because of open switch.You need to replaced it.
And check some fuses if any and other burned electrical wire.Replaced it also.
