I have an e series rainbow vacuum and when using non-power wand to clean hardwood floors it only blows out, how do I reverse the air flow to suction

SOURCE: remove suction motor on rainbow vacuum

Take off the water tank, remove the screw, should be four, that will separate the 2 pieces, remove the rubber seal, remove the screws, 8 If I remember, disconnect the wires to the motor, it should pull out. Replace motor, hook up the wires, screw it back together, glue the water seal back on.

Being an E series some have a corrgated filter in the top, there is also a filter on the back. Could be a motor problem, not turning as fast as it should, in which case you will have to replace the motor. You might check, some had a 10 year warranty on the motor. If you are the original owner and only have had it 5 years, then it may be covered.

Could the debris from plaster sanding cause my rainbow series D4C vacuum not to work? If so how is the best way to clean it?

Hello,
I would advise you to ALWAYS to FIRST UNPLUG YOUR VACUUM before beginning any service procedure. The Rainbow D4C will still work but not @ the highest efficiency rating – the suction will be reduced because the sheetrock dust gets into the motor and the fan blade(s) Quan 3 and would need a professional cleaning 1st or 2nd. Replacement of the motor; if it is too serious and or too expensive. It’s a good vacuum back it is suggested that people use a good Shop Vac for the sheetrock dust removal. Feel free to contact your local vacuum cleaner dealer in your area or you can try to repair and change out the fans, clean out the carbon brush area and cleanup the armature. 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.

WARNING WARNING Danger danger Will Robinson! The power head "wand" and the hose from the body of the vacuum have shorts in them. While my wife was using this machine.. she started smelling plastic.. seeing whitish smoke and then sparks... The pin connector arc'd through the plastic... Some research on Google found that this has been a large problem for Electrolux, when i tried to call the factory.. robots.... no solution. Then I contacted a distributor and they informed me that it was not really that big of a problem. Only later to say, that they had replaced ALOT of them. My unit was past its warranty period so I just hardwired it. (now the unit is only two pieces, body and hose w/wand.)

With years of use, you will collect a layer of "micro dust" on the impeller (the fan part) which reduces the efficiency. A toothbrush and some mild cleaner with gently scrubbing will restore it's power.
The impeller is that parts that spins that you can see when you take the top off to fill the water tank.
Hope this is the answer that you need!
