Problem with E series rainbow, motor starts then slows down to a halt and smells.

I have an E series rainbow in which I'm not sure if the motor is going bad or if it just needs new carbon brushes. The machine produces a foul electrical smell and then just quits. Could it be the armature & brushes? Or should I just replace the motor completely?

    I just replaced the brushes on my d2 rainbow and it was working well for a few minutes, then slowed down and smelled like an electrical fire. Just wondering if I may have put them in wrong.

From what you describe, you will probably have to replace the motor. But you could take it apart and see if it just needs carbon brushes.

The rainbow sat for too long on the water now wont run

So depending on how long, you may have rusted out the bearings in your motor, especially if it sat so long as to eat the glue off of your gasket.
Sounds like you may need a new motor, gasket, baffle plate and separator.

Burning smell

The response by Lynnette is in reference to the power nozzle....if you are having this issue with the main unit, then it could be the armature is starting to go bad. Have your Rainbow in front of you and give us a call. We can walk you through some steps to narrow it down.

I smelled something burning one day , but i kept using my d4c, now the motor part does not run but the top plug in will run

I work on Rainbows. D4C-E2 etc. Not sure what you mean by the top plug in. There are two motors in the rainbow, one in the main unit, one in the power head. Where was the odor coming from? email me back with more info, I can help you with this. Jerry

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.

You can get manuals either here, or here,

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

Thank you,

When I turned on the vacuum it started to smell

the vacuum is either shorting or the motor or brush assembly is rubbing something.

Rainbow E series

The belt looses it tensile strength (tightness) over time. But it's the part about funny sounds and shutting down that concerns me. If it smells like a tire fire then it's the belt if it smells like plastic and burned hair then the motor has a bad field or armature. Probably one of the carbon brushes got hung up and burned a segment in the armature.

Burning Smell

Check the carbon motor brushes, there might be arcing on the armature. New brushes may help if the armature is ok.
