Rainbow Vacuum Cleaner starts slow smells hot

Cleaner is actually SE model. When I turn on my cleaner it starts at a slow speed--then the motor heats up and smells HOT as it struggles to come up to speed. I don't want to burn it out and I've taken the cleaner apart but I can't see what the problem is. It seems like the impeller is slowed by something (rust maybe) but I can't get it apart enough to see what is under the impeller. Can't figure out who to get bottom apart. Sound like scale, rust or bearings? Help? Ideas?

    We have same model with the same problem. Motor started to smell bad. I took the vacuum apart to the point of reaching the motor and it appears the bottom will not come off. There must be some secret to how this can be done.

    I have a similar problem. Mine does not have sucking power through the hose as well. The stuff that gets sucked up, gets stuck underneath the cover for the roller. I also have tried everything I can think of, I have not taken the vacuum apart, figured this would mess with the warranty. I thought the motors had a lifetime warranty. I am in the process of contacting rainbow, if I find out any information, I will post it and let you know.

I would suggest that your motor bearings are packing up. You will eventually harm the windings by overheating (although there is a thermal limiter). The bearing replacement is a job for a service shop unless you are pretty handy.

I started vacuuming and the vacuum motor slowed down, then stopped. I smelled a burning smell. Then I discovered the next day that the bag bottom was wet and falling apart. Sebo X4 model


sucked up liquid goes with the air through the motor
that would cause the motor to burn out
with the current low cost of new vacuums , the repair /replacement of the motor would be close to a new unit
take it to an appliance repair shop and get a proper diagnosis and quote

My rainbow se squeals and smells when running. How do you fix that?


Flip it over and look at the belt that drives the spinning brush. There is something tangled in it (if so, pull it out), or the belt it is about to fail. Google a vacuum repair store in your area to buy a new belt. It is usually a couple of screws, lift out the brush and slide the old belt off, new on and put it back together.

Or, or, let the guy at the vacuum cleaner store do it.

How to get to the rainbow SE vacuum off/on switch.


Hi, here is a walkthrough on how to get to that part here. Steps 1 - 14 on how to access it, you will need to take apart the housing to get at it. If you need a new switch you can find that here. Rainbow did redesign this switch, so you will need to look at the wiring diagram if you are installing a new switch.

May be a bad bearing and possibly be serviced by a dealer. I think the newest models don't have bearings.

Hi, there is no reset button on a Rainbow vacuum. There is a safety switch on all E series and E2 series Rainbow vacuums, that keep it from running without the water basin on it.
If you have any more questions let me know. I am a Rainbow seller, and a Rainbow expert also.

I bought my rainbow se vacum 4 years ago and I was using it and suddendly stoped working, I try to on no power I on and off not working at all. what shall i do is there posibility to work again.pls.help...


Hi, there is no reset button on a Rainbow vacuum.

All SE series vacuums have a built in thermal and load fuse on the motor, and if it blew, it has to be replaced, or wired directly, with out it on there.
Motor brushes are usually the source of a non working Rainbow D4 and SE and all model Rainbow vacuums and when they burn out, they usually take the motor armature with them, from excessive heat and flare electrical arking to the armature. It is probably the thermal and load fuse, that is your problem, if you did not smell any electric burning type of smell, before it quit. It could be the power switch, but not as likely as the fuse. If you have any more questions let me know. I am a Rainbow seller, and a Rainbow expert also.

Thank you,

Posted by ray_s51 on Apr 20, 2008
My Rainbow SE works and runs strong but when I switch it on and off for approx. 20 to 30 seconds the motor makes a loud squealing noise. Do I need to oil something or what? Nothing smells, it does not make the noise all the time, but it does more often than not. Thanks

Hello,
I would advise you to ALWAYS to FIRST UNPLUG YOUR VACUUM before beginning any service procedure. Rainbow E Series Canister Wet/Dry Vacuum.

The Rainbow has 3 fans in the bottom of the motor and if they are weak they will make noise from the motor unit. Watch out… the repair of the Rainbow may exceed the cost of a new motor of which will solve your problem of noise and separator --- compare the cost and the labor and make a decision. The separator is part of the armature, the separator should be able to be removed and that might be one of the things making noise. As normal maintenance the separator should be removed and cleaned after every use and re-installed, then place a newspaper or towel under the motor unit and turn on the Rainbow and spin the moisture out of the motor unit. This should be done every time you use it. If you have further questions please feel free to contact your local vacuum cleaner dealer. . So if you need further assistance, please feel free to contact your local vacuum cleaner dealer in your area or in the yellow pages, or contact the factory phone number or website to further assist you with your questions.

How do I remove the pin on my Rainbow Vacuum Model SE clips?


When I used to repair Rainbow SE vacuums for a living, I had a long nail of small diameter that I had filed the end off of just for this purpose. The pin you need to remove is grooved on each end to "catch" in the plastic housing, but a slight tap with a hammer, using this "nail" will do the trick. When you're ready to re-attach it, just tap it again to put it back in place.
