Question about Rainbow E series Canister Wet/Dry Vacuum

1 Answer

Rainbow E series sounds "whiny" and loud while running

We recently purchased a used Rainbow E series made in 2004. It sounds whiny and high pitched when it is running. It works fine, but worries me. A servicing place told my husband that these models go bad because of the filters needing to be changed, and people not knowing it. Then the motor has to be replaced etc. Has anyone else had this problem?

The whinning sound may be the bearings are bad. This will have to be taken care of or it will wear your motor brushes down very quickly. It is not generally caused by the filter, but by not be cleaned properly and may have been stored on its water basin.

Aquamate is making a high pitch sound and the brush isn't moving


Check the belt and brush roller on your Aquamate. The belt may have slipped or be broken. There also may be a build up of hair or fibers stopping up the brush and preventing it from turning.

Rainbow motor makes loud noise


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?

Rainbow Overflow .. HELP


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.

Thank you,
Ralph
One other thing, water sucking through your vacuum should not hurt it. It is not good though, but will not make it not run.

Thank you again,
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,
Ralph

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.

Loud rainbow and water leaking


If pieces are missing or broken I would try and replace the piece. You can usually get these items cheap on Ebay.
