How to clean the dc29?

Will it power up without the hose attached? If it does then you have a clogged hose. If not, there is a circuit board by the motor that may be bad.

No power in power nozzle
Posted by pjs5451 on Apr 06, 2008
Vacuumed with power nozzle one day working fine took attachment off to use crevice tool reattached power nozzle and no power whatsoever.

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 Power Nozzle does have a reset button on the newer model on the top of the power nozzle, just push it and it should reset, or check all your pigtail connections to make sure they are connection and the cord leading to the actual Rainbow Vacuum itself. Out in left field might be that the power nozzle motor could be shorting out or not working or dead and might be in need of replacement. Check the cord for any frays or bad connections. If you have a problem please feel free to contact your local vacuum cleaner dealer in your area. 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.

SOURCE: how to get rid of dog smell

I had this problem along with a clogged filter. I used the solution for clogged filter here on Fixya and the dog smell went away too. It has to do with the flange on the cylinder getting pushed up out of position. Give it a try.

The motor overheats from the filter being clogged underneath the canister or the canister or both are clogged-without the air flow the motor overheats and shuts off as a precautionary measure.By letting the motor cool off it will start again but will turn off shortly if the filters are not properly cleaned.Hope this helps everyone.

I had the same problem. The agitator stopped turning after I sucked up a foreign object (my wife's watch) and it got jammed in the intake. After removal of the watch the agitator did not spin when turning on the machine, and the reset button never deployed (it remained buried in its housing and would not depress with a paper clip). The agitator was not bound and I could manually move it in both directions with ease. Faced with prospect of paying $125 or more for a repair, a good sharp kick to the chassis from the top promptly fixed the problem. I have found that kicking malfunctioning electronics often works.
