If you have used it alot, then the brushes are PROBABLY worn and failing. You should take it to have this checked as it will wreck the commutator to run that way requiring whole motor to be replaced. Take it to a repair facility.

Vacuum has power but wont run


From your question it sounds like the Rainbow will not run on high speed. Very good chance the Controller Asm 120v e2 Silver Gold is bad. Call us when you are able as we can replace at a discounted price if your machine meets the requirements. Contact Us

My rainbow E2 will run on High speed,but not the low speed.it's as if no power is getting to it,when.you try to switch it on low,but works fine on high


This could be one of two problems. It could be your switch is broken, preventing it from going to low speed. Try clicking it, does it still make a distinctive click sound, does it feel loose? If so it may be your switch: Rainbow e2 power switch
Otherwise if may be your computer in your E2 is starting to go bad. Often times if Rainbow stops going into one of the speeds it is due to a computer going bad. This is an expensive part and repair, so you should probably take it in and make sure it is the computer. Rainbow E2 controller 120v

Why won't my Rainbow E Series won't turn on?


It sounds like your motor is probably dead.
You would need a new motor if the Rainbow is getting power and the power nozzle works.

You can find a new motor here:

How do I get the motor out of the power nozzle on the E-series?


The eSERIES Rainbow has several versions of the power nozzle. Some screw apart and others have snap connections. Look at our website on the manuals page to determine your model. You can also call us and speak to a Rainbow Specialist.

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.

Thank you,
Ralph

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!

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.

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

Thank you,

Possable broken/Disconected wire


hope you have checked the obvious first ..the plug are all the conections tight including the fuse? if so check the vac's switch for loose conections .lets face it the mains feeds the switch the switch feeds the motor unless you have a speed switch. sounds like a fault that could be cured with a bit of investigation good luck farr64
