What is the part number of the trigger you purchased for replacement? Needed information so we can understand exactly what configuration you are working with.

Check that you are getting power to the brush roll motor. Many Rainbows have a reset button on the power head.

If it a rainbow its stopped up somewhere did u know u can attach u hoses to where the air comes out it will unstop them b sure to do it outside just in case it wikl make a mess if that's problem. I have hsd rainbow 13 yrs woudnt trade I for nothing

Depending on the age of the Rainbow, it could be the bearings. Does the noise happen with just the Rainbow or from the power nozzle?

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 hacuum. 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

There is a motor in the power head that could be out or the receptacle, electric cord on power unit or loose wire in power head.

Wait 12 hours empty unit and restart.

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

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.
