Right out of the box, the vaccuum has been making the grinding noise indicating that something is blocking the beater bar. There is nothing blocking the beater bar, but the clutch piece appears to drop lower than the indicator line for carpets when extended for normal carpet vaccuuming. The noise is happening intermittently on the carpet setting. Do we have to take it back to the store, or is there a fix for this problem?

something wrapped around beater or damaged and or debris at bearings

There are a few things a flashing light could mean. One is that the beater bar has something stuck on it. Or, it could be that the bag or canister is full. Then again, maybe something is stuck in one of the intakes. Be careful when checking the beater bars. Unplug the vacuum before touching them, you wouldn't want your hands getting injured or fingers broken:( Clear anything that is wrapped around the beater bars, hair, string, etc., and then check the hoses to make sure nothing is stuck in them. If you have suction, the interior is clear. If not, then check in there to make sure nothing is clogging it. Good luck and be careful:)

Sounds like you're right. New motors are available at your nearest Aerus Electrolux store. They used to charge the same amount for selling the motor and letting the buyer install it, or for installing it in the shop. Worth checking in to.

The belt that rotates the beater bar may be damaged - call the Dyson helpline for troubleshooting and for a solution to the problem.

I have a dyson 17 animal and have a loud noise comming from the beater bar area.Also I don't think the hight adjuster is working properly.

This is a bot of a blind guess, I don't know the model. But most power head cleaners I have worked on use the suction of the vaccuum to spin a turbo fan in the head (like blowing a child's windmill). The head not spinning is usually because there's not enough **** to spin the turbo fan. Check for:
Gummed up brush bearings (dirt or damp) making the brush harder to turn than it should be.
Poor suction caused by a blocked or partially blocked pipe.
An obstruction that is tactchin the beater or the turbo fan.
Blocked filters on the cleaner, reducing the **** and thereby not providing enough vaccuum to spin the beater.

Is the noise a loud screaming or a grinding/vibration? The screaming is an air flow problem and you'll want to check your hoses are clear and all the seals are tight. The grinding is an issue with the roller/belt/clutch/motor/housing. From what I'm reading, both problems are common on the Dyson animal.

I just came from the repair shop. There is a recurring problem with a bearing coming out. Repair guy turned it on & said that loud noise is a symptom of that exact problem. This is a warranty item, as is the belt & on/off switch. Dyson comes with a 5 year warranty, so call their 800 number to get the name & address of an authorized repair shop.

Belt jumped off beater bar and jammed it! Disconnect belt, does imotor run. If yes, reconnect belt turning beater bar by hand to see if it is smooth. Carefully, reassemble and run it!
