Question about Dyson DC17 Animal Bagless Upright Cyclonic Vacuum

5 Answers

Dyson DC17 Animal

There is a valve on the back left that looses suction. If you tape it with your foot a few time it seems to reconnect but it is not picking up very well when running on a hard surface. Right now it is not running and it has done this before. It seems to get over heated and needs to cool off. I think something may be trapped but I can only remove the bottom plate and can't get to the area that seems to have the problem.

    We replaced the filter and nothing has changed. My husband took the DC17 apart as far as he could and cleaned everything out but there are 4 tubes leading to the purple cyclone top and 3 of them are blocked. Do you know of any way to get into that section of the vacuum?

    I think we have the same issue.The little valve like thing with three little pie shape openings hisses alot. Not sure what it's for.

    i also need to remove that purple top, i got in there thru the oval
    opening with needlenose pliers and pulled a bunch of stuff out of the
    tubes but they are still pretty clogged. i cannot find a way to unclog
    them. i cant believe these marketing people at dyson can advertise
    'does not clog' and get away with it.

    I have the same exact problem. Somewhat happy to see that someone else is asking exactly what I am asking - but then again, really disappointed to see others with what is a common problem. When will Dyson realize that this `cyclonic' action actually almost braids rope out of pets hair, and that's what gets clogged?? Anyway, I had the same problem with the valve on the back and yes while it can be caused by the filter being clogged up or the u-bend pipe being clogged, it can also be the cavities in the top of the cannister (purple top). That's where I am. I can see a little hair up there but I can feel loads of when I poke through the holes, just can't get at it.
    DYSON, without breaking my machine, IS THERE ANY WAY TO OPEN THE CANNISTER TOP? THis makes 3 people trying to ask the same question, can we get it answered?? thanks.

    I had the same problem so I called Dyson support. The support rep said that noise indicates a clog or blockage. They walked me through taking the vacuum apart and checked for clogs. There was one clog in the "wand" but it still had an overall lack of suction. She then asked me to check the canister and all the small holes in the grey base were clogged and there was dog hair in the top under the purple cap. Further more, the cannister was missing some black rubber ring at the bottom that would cause it lose suction.

    She said they have an updated cannister for this model (DC17 animal) and would be sending it to me.

    if you remove the clear canister and look at the bottom of your cyclone assy. with a flashlight you will notice 4 torq screws. you can remove these to diasemble your cyclone and remove the hair and debris from the inside of your purple housing.

I have the same problem with my Dyson dc17...there is dog x2 hair collecting in the 'cylinders' just underneath the purple cap on top of the cyclone/canister. And i can see twisted 'braids' of hair coming out of each pea-size hole. I called Dyson's Support number and after they asked a few questions about the round filter (tell them you clean it every month or so), the representative told me that you should not see anything collecting on top of your filter located at the base of the canister (mine was covered with dog hair, etc.). They told me that nothing larger than minute dust particles should be there...which eventually travel into the purple cap. They said the cyclone canister has since been redesigned to correct the faulty rubber seals, etc., and they are going to send me a whole new cyclone/canister within a week or so. so call Dyson directly before you try to get inside "the purple chamber"...I know I could not figure it out!

I had the same problem, called dyson and they sent a new purple cyclone thing.  I am still trying to clean the old one, latest thing I tried was drain cleaner- didn't work.  I will post back if I can clean that stuff out of there.  But I would call dyson and tell them you checked all of the normal clog places and it really is the purple part that is ruined- like i said they sent me a new one.  I just hope the new one doesn't do the same thing as the original.  Best of luck

Here are instructions for disassembling the canister unit:
http://www.ehow.com/how_5028186_clean-dyson-dc-cyclone-canister.html
I just called Dyson and found out that the black rubber seal at the bottom of the gray inner cyclone component MUST extend 3/4" beyond the end of the plastic unit. Otherwise, large dirt particles (hair, etc.) will clog the filter. They are sending me a new canister.

    They offered the same solution with me, also adding that I should clean the filter in the bottom of the unit. I STILL have lint & debris building at the top of the canister, clogging the vent holes. I think it's a product defect. I'd never buy another Dyson again.

I had the same problem...probably something caught in "U-bend." At the bottom of the hose there is a plastic u-shaped pipe. Above the pipe is a "screw." Un-screw into the unlocked position. Pull the u-bend off and pull out any stuck debris. Put u-bend back on and lock screw back into position.

First remove and check the filter pad in the lid of the machine and the exhaust hepa as well if it's been over a year from purchase they both have to be replaced.
Make sure that the pipe on the back is fully engaged and latched. and if you can see the little flexi hose underneath then you can pull the rubber fitting off and check it for clogs as well.

    Dyson has sent me a new canister, suggested I clean the filter monthly (only 1 cat in the house) & to make sure all hoses are clean. Still have the same clogged vent problem. I think it's a product defect & they know it. I'd never buy a Dyson again.

How to Fix Vacuum That Lost Suction
If there's ample suction but the machine won't pick up material, check the hose for blockages. Disconnect the hose from the vacuum cleaner and inspect it for any cracks or holes. If any are found, use duct tape to repair them - it might not look great, but it does the job! Where there's a blockage in the vacuum cleaner, clean it out by pushing a long, thin object like a broom handle through the entire length of thre hose. You can then reconnect the hose and try the vacuum again. It's worth checking the hoses a few times every year for cracks or splits.
If everything else appears to be fine but the vacuum still won't pick up, take a look at the brushes. Turn the vacuum cleaner upside down and clean hair and other material from the brushes, especially at the sides.

Dyson DC14 hose won't extend and floor unit lost suction


Sounds like the exhaust side is clogged. Remember a vacuum pulls air into the cavity, but for it to work properly it also has to be able to exhaust the same amount of air it takes in. If the exhaust is blocked it will continue to suck air inside and collapse on itself, which is why your hoses are getting shorter and harder to move. Check the exhaust system for any blockages, perhaps the hole you taped was the exhaust.

Loss of suction?


Mine was doing something similar. When standing upright, suction was strong through the hose. When I lowered the handle to sweep the floor, the bar underneath would spin, but the suction seemed horrible and the dirt inside the window wasn't spinning/cycloning like it used to. I called Dyson Support and they had me lay the vacuum on it's left side. Now look underneath and you'll see a clear hose, one end connected to the upper part of the vacuum and the other to the lower. I removed the tube and it was completely clogged, especially at the point that it connects to the bottom part of the vaccum. After that I reconnect and it sucks like the day I got it. Dyson support is still sending me a new "internal hose" but I don't think I need it.

I have unscrewed all the screws and can't get bottom off.


Here is a possible solution. If the vacuum sounds normal when the green light comes on, then the issue is a suction bypass. Kenmore built a suction bypass in to help cool down and protect the motor should someone either never clean the filter, empty the canister or somehow manage to clog the hose. There is a spring holding the bypass closed and is overridden by vacuum suction. I guess the spring becomes weak, allowing high suction to pull it open which in turn reduces suction so it closes again. It can do this several times per second making a loud racket and slightly affecting performance until the sensor goes green, then the vacuum suction is too low to overcome the spring tension thus why it sounds fine then. The trick? The very hard way (what I did) was to open the vacuum, open the casing where the spring is and pull it apart slightly to increase the spring tension. The easy way is to put tape over the hole where the bypass is. The inlet is under the hose track on the back on the right side as you're looking at it. The hole is about the size of a quarter and you'll see fins across the hole. The tape would keep the suction. The motor would still pull back the bypass but since tape is applied, there would be nothing to reduce the suction thus keeping performance and reducing the noise. However, this circumvents the intended design so you do so only at your own risk.

Dyson Animal, lost suction and bypass valve seems to be loose


Dear terrygivens, 2-17-2009 4:12am EST (USA)

Most suction problems are caused by a clog from picking up something you probably didn't see or if you have pets an accumulation of pet hairs!

To clear it out take a metal coat hanger and unbend it til it's straight, then bend the end and tape it so when you push it through to unclog your vac it doesn't rip the hose.

Push the coat hanger in from the bottom brush area through the opening where the suction is. Also push it in and out anywhere else you can......You'll probably find something clogged....keep working it til it loosens and intermittently turn on the suction.

If you have a second vac with a hose, use that hose for suction on the clogged vac!

This should do it!

Vacuum hose has little suction.


There is most likely a clog in the hose. If the hose has poor suction the foot probably has poor suction as well seeing that the hose is what gives the foot assy suction.

Loss of suction when using upright. Suction remains for samll tools


I checked all the pipes and seals. There is a flexible pipe which you can see underneath that connects the front rotating brush assembly to the vacuum system. This pipe can crack and loss of suction occurs when using it upright. The pipe can be repaired temporarily with strong fabric sticky backed tape (e.g. carpet seal tape). A new pipe can be fitted with a few tools.

No suction when carpet cleaning. Also won't stand upright


Its possible that it may be blocked in the foot of the vaccum. try going through your instruction manual to locate details on how to disassemble the suction brush and connecting ducts. If you dont have one then use this link to download it. http://ubermanuals.com/node/1870

Let me know how you got on
