    Since you can see the motor: is there white scale on the outside of the motor? Was the acorn nut rusted?

Unfortunately that large beige box that was resting on top of the motor is the computer that controls the 2 speed function of the vac.

The first thing to check is motor it's self, there are 2 brush 'boxy things' at right angles to the armature (the part of the motor that spins). Check those and make sure that the brushes are evenly worn and in contact with the motor. Next see of there are burn marks on the motor itself - it should be copper in color.

If this looks fine, sorry to say, the computer might be the issue ... not cheap.

Hope this helps

Let us know, might have other ideas

No power


You must have a late model 2006 or newer E2 two speed Rainbow vacuum that has the white foam padding in the canister, to dampen the sound of the motor, and has a red light on the computer board.

I hate to tell you, but your computer is most likely the problem, and is out on your E2 two speed vacuum.

The only solution is to get a new computer for it.

It is realy not worth replacing it, because it may also be the motor. The E2 is a very high tec system, and is not like any other vacuum. When you turn it on, you are not turning on the vacuum. You are turning on the computer, which is controling everything.

I could supply you with another canister, if you are interested.

If you have any more questions let me know. I am a Rainbow seller, and a Rainbow expert also.

Rainbow E2 2 speed vacuum motor whines at startup


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!

My e series rainbow smells very badly... my teenager often leaves the water in for days and that nasty smell has saturated the sweeper itself. How do I get the smell out


You should always put a new hepa filter in any E and E2 series Rainbow vacuum, when it taken to a new home, or every two Years, or so, or if your Doughter makes it get funky smelling. :-) It will smell like the home that it was in, or how ever it smells, until you do.

You can also use fragrances, and deodorizer air freshener in your vacuum, which not only eliminates odors, it add fresh aromas to your air that you breath, in your home, also.

Replace the hepa filter first thing.

The water separator is the thing that spins in the center of the motor where your water basin attaches to it. It looks like a cone shaped fan looking thing. It should be cleaned after every use.

Use your Rainbow separator cleaning brush, or a tooth brush, if you do not have the Rainbow one. They are just like tooth brushes.


Never store your Rainbow canister on your water basin, with or without water in it. It can and will ruin your vacuum in dew time.

E2 gold series - makes loud noise on start up


That is normal. All E2 two speed Rainbows make that sound. It is because it has a brushless motor that the computer is controling, and the computer is controling everything. The motor rotor has no coils on it on the rotor, which is very small and light, and the computer gives it a small power boost when you first turn on, then increases the power until ir reaches full speed.

Rainbow vacuum-water not spinning


Remove hose and turn on the unit with nothing on the intake - see if it helps - feel the suction with hand.

a) If it works fine without the hose - look for a clog in the hose, wand or the nozzle

b) If the suction is weak even without the hose:
Clean the separator,
If this is e-series or E2 Rainbow - remove HEPA and try vacuuming without it (sometimes it is too dirty so stops good airflow). New HEPAs HERE.
If this is SE Rainbow - remove exhaust cap and if there is a sponge - take it out

Still no luck - It has to be serviced

Good Luck,
Rocky

I don't know how to take apart me Rainbow e2 series vac.


I recently took mine apart because the motor stopped working. Realized the brushes were pretty well worn down and one side was completely gone. I was looking on the internet for detailed instructions on how to take it apart. I ended up just ripping it apart with no problems but made a tutorial to help you guys out. Here's a link to it

http://www.vacuumcleanerforum.com/f20/21715-how-take-your-rainbow-vaccum-apart.html

This is for the e-series vaccum, not the e2 but they pretty much have the same design and same motor (e2 has a 2 stage motor).

Let me know if you have any questions

Changing the filter in Rainbow e series


Some of the e-series has a corrugated filter in the top section. To get to it, remove the clear plastic panels that are the sides. Most have 3 screws on each side to move, then the top half will come loose. There also is filter on the back, there is a door to remove to get to it.

Older Rainbow Noisy
Posted by Capt_Troll on May 06, 2008
I Have an Older Rainbow (i think it's a d4)
my Old roommate ran it once without water.
it Still works now (with water), but
it's Very noisy on start up
Also I Can't seem to remove the separator (no instructions) but the nut at the end of it appears to free spin the motor when i try to turn it.
Can I Take this apart and Clean/lube it? And if so how? Or is this thing on its last legs? 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 D4 is an older Rainbow Vacuum and the part where 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. Other wise the Rainbow has 3 fans in the bottom of the motor and if they are weak they will make noise from the motor unit as well. Watch out… the repair of the Rainbow D4 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. 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.

Rainbow e2 series


Does the separator turn easily by hand? If it does, may be there is a problem with the carbon brushes. If this model is one that has the computor board mounted on top of the motor, there may be a problem with it.

Rainbow SE makes Squealing Noise when switching it...
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
