My dyson DC17 will not lock back into stand up postion what is wrong?

SOURCE: Power shuts off on my dyson dc17 animal

My DC 17 Animal would only work when the brush was in the down position & the hose attachment wouldn't work at all. There was no suction. We had to take it in to be serviced & discovered that there is another filter in the system that Dyson doesn't tell you about. The person at the service center said he sees this problem a lot with this model because there is nothing about it in Dyson's consumer documentation.

SOURCE: How to replace belt on Dyson DC17

Preface: Dyson folks were great, answer so simple I was embarassed after I called. 5 minute fix.
1. Loosen 3 screws from bottom plate using flathead screwdriver or coin edge and remove it.
2. Wiggle roller until it pulls straight out.
3. Squeeze new belt and loop it over metal drive gear (you'll easily see the gear).
4. Keeping belt on gear, insert edge of roller through belt and rotate the roller while pushing it through belt until it is inside the belt, then continue rotating roller and sliding it over until belt is in position over gears on roller.
5. Insert roller into slots on that it came out of, reattach bottom cover and its done.

Take off the cyclone canister and flip open the filter cover. (The U-shaped tube at the bottom of the vacuum is probably already off-if not, release the lock with a screwdriver and remove it.) Release the vacuum from the upright positon, so that the head is extended. Align the value pipe assembly so that the clear tabs line up while the small extension off the value pipe faces the front of the vacuum (ie, is near the filter area). Now you have to carefully twist the value pipe clockwise while lining us the small extension with the black groove inside the head piece by moving the head back into the upright positon at the same time. Replace the U-shaped tube.

I had the same issue. Got on the phone with Dyson. THe vacuum has a safety feature where if the motor gets too hot it cuts off. You have to leave it for 45 minutes or so and then it will work again. There is an underlying issue though. My problem was the black gasket thats in the debris bin shifted, probably from when emptying i pushed it on something. The black gasket should actually hang off the bottom like a skirt and the 2 groves should fit in on the groves of the gray mechanism. This seal is what provides 100% suction. Because of this..my vaccumm has been accumulating pet hair by the belt which i hear alot of people talking about and especially in the filter area. This is because I broke the seal by not having the gasket in place properly and it wasnt sucking 100%. They are sending me a complete new cyclone unit which has the debris catcher as well as she said its probably so caked up with debris it will never work again 100%. no questions asked they are sending it to me free of charge.

So if you remove the clear cyclinder debris catch thing all you will have is the purple cyclone on top and on the bottom is the black rubber gasket....if that shifted and is no longer hanging off...call dyson cause your vacuum is probably caked up...it will never work properly...they will send you a new part
