Not a good sign. If your Rainbow is SE or newer - separator should not spin freely.

Some may recommend torch but I am afraid that you may end up melting some plastic parts so be careful. I'd say put a wrench on the nut, hold the separator and press it towards the motor (thus holding the armature as much as it is still possible) and then hit the wrench that is on the nut with another one - create momentum.

If this does not work - you can use pliers to destroy the separator completely so you would gain access to another nut that is under the separator so you can hold the armature with another wrench.

I can not guarantee 100% that you will succeed as sometimes those nuts are so rusted that you have to have the armature held in a vise.We usually disassemble the motor so we can hold the armature by hand or in a vise but if you do not want to go that far into the motor - use described above method - maybe it will work.

My kids were in charge of the Rainbow, but they moved out. My husband surprised me by cleaning a dirty rug. Neither of us know how to use the Rainbow, but I at least know that you're supposed to use water....


Your Rainbow might have been damaged. It would be advisable to take the machine to a shop and have them do a cleaning on it. The water is the filter, and there is a separator between the water and the motor. The separator only prevents the water from entering the motor. The dirt that goes in the water is no longer airbourne, so it cannot enter. Without water, the dirt is still airbourne and some of it could have entered. I am sure that most of what was picked up landed in the basin. Is the separator(the little nut on the bottom of cleaner holds this in) full of fluff? Take off the separator nut(there should be a wrench/toothbrush tucked in under the cleaner that is used to remove separator and clean it.) Is there fluff visible up in the machine? If so, definitely take it to a shop. The separator must be cleaned after every use. Never store water in the basin. Those are the 2 main rules for care and use of your Rainbow. Well, good luck with your Rainbow. They are truly great vacuums. Let me know if this helped you. Thanks Rene(the VAcuum Doctor)

Water leaking from out of the heppa filter


Reasons for that to happen:
a) You have tilted the vac while vacuuming
b) Used the Rainbow without separator (basket like thing on the bottom of the motor)
c) Overfilled the rainbow tank with water (may have happened when shampooing with AquaMate)

Clean and install back the separator, remove HEPA, Set the Rainbow on empty water pan (with HEPA removed) turn it on for a while so everything will dry. Install new HEPA.

You will have to get a new HEPA filter (you can find them HERE)

Good Luck,
Rocky

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

Cleaning the filter on a e series rainbow vacuum
Posted by jonesjpc on Jul 06, 2008
This one does not have the tabs to depress as but has two screws in that area still doesn’t see how to get to the filter. Also I need instructions to replace power cord; On the E series single speed.


Hello,
I would advise you to ALWAYS to FIRST UNPLUG YOUR VACUUM before beginning any service procedure. On the Rainbow E Series there really is no actual filter – the water is the filter for this particular vacuum. Before you remove the separator under the motor, place a newspaper or towel under the Rainbow without the water pan under the vacuum and then turn it on for a short period of time and spin the water moisture out of the motor and separator; then some of the maintenance is to remove the separator under the motor and clean that and then replace it. As far as replacing the cord there are screws under the Rainbow that need removal and then you can get to the end of the cord for replacement. The easiest way is to mark your wires and the cord will be much easier to replace otherwise check the owner’s manual for cord replacement or check with your local vacuum cleaner dealer in your area or to cal the cust serv @ the Rainbow factory for 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 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

Cleaning the separator


Try spraying something like WD40 around the shaft, then if you have to, use 2 small flat blades that will fit under the edge of the separator and keep working it until it pops loose. It is just crude and calcium from water that is keeping it on.

Rainbow e series


It could if the separator is binding, or dragging, when it turns, causing the motor to over heat, that maybe what you are smelling. If it is, then replace the separator.
