Having problems with your Hoover U6437-900 / U6439-900 Windtunnel Bagged Upright Vacuum ?

Dirt finder I have a Hoover U6439-900.  After the cleaner was used a few times, the dirt finder light cycles between green and red on the regular setting and will not go to green.  On the sensitive setting, the red light stays on most of the time.  I have tried to run the cleaner to remove any dirt but have not solved the problem.


Answers :

The sensor may be bad, or it may be coated over with dirt. Re,ove the hose at the back of the vacuum, the head of the sensor is down inside that opening, reach in there and clean it off and see it that corrects the problem, if not replace the sensor.

I have just purchased two (2) Electrolux Nimble vacuum cleaners. Not one, but both, straight out of the box, the beater bars will not run. It turns on, select carpet, and lower the handle, the red light to check beater bar/or filter lights up. You can reset the light by unplugging the unit, then plugging it back in, but with same results.
