Having problems with your Dyson DCO7 Animal Bagless Upright Cyclonic Vacuum ?

Dyson dc04 motor runs but has no suction.

\015 Hi, I hope you can help me. \015\012My Dyson dc04 suddenly stopped having suction and makes a high pitched sound, it seems to me that the motor is running disengaged or some O ring slipped. Does that sound reasonable?\015\012I've started to open the engine unit but can't seem to get it open, is there a short explanation or manual on opening the unit, there is something that I'm missing.\015\012Thanks.\015\012 \015\012 \015

Answers :

I would make sure it is the motor first by isolating the sounds to just the motor. Take off the dirt cup, both filters, and belt, then run it and see if the sound is still there. If it is, you need a new motor. If it isn't, you need to look for a clog, or bad roller bearing.

\015\012To take the motor out first undo the wiring running down the backside of the unit inside of the switch housing. Then take the four screws out that hold the outer motor housing on, and the rest pops apart. Once you get inside, the gaskets make it a really tight fit, so you might have to hit the motor shaft with a rubber mallet to get it out and use penetrating oil on the bottom gasket to get the new motor to slide back in.

I'm trying to figure out which dyson vacuum is better, the DC14 or DC17. from what i read, the DC17 is the newer model of the DC14, the DC17 added an extra motor for the brush, but from the dyson site, the DC17 has less suction power. it went from 250AW (dc14) to 220AW (dc17). is that a significant difference that i should be worried about?


Hi,DC17 is much better than DC14. I always believe User's review are much better than what Features Company usually Displays.Read :-http://www.epinions.com/review/Dyson_DC17_Animal_Vacuum/content_404790546052 ... Vacuums
