Question about Dyson DC07 Bagless Upright Cyclonic Vacuum

1 Answer

Dyson, pressure release valve keeps going off and staying open.

I was cleaning with the Dyson a few days ago and it began to get louder as if pressure/vacuum was building too high. Then the pressure release valve opened, and now everytime I turn it on it takes a couple of seconds for the pressure/vacuum to build again and the release opens. I cleaned everything I can see to clean, and don't see any clogs! Please help.

There are a couple of things you can do, the blled valve (pressure valve) activates when there is a blockage in the machine. You just need to find the blockage:

1) To check for blockages from the bottom of the machine. Remove the:
(i) U-Bend (stand behind the machine and look next to the right-hand-side wheel, it's attached with a rectangular clip next to the
long gray hose - push the clip and pull the U-Bend off, make sure its clear - if there's a blockage remove it and continue with the
blockage check to ensure that the entire machine is clear)
(ii) AI Valve (stand behind the machine and look above the right-hand side wheel, it's attached with two buttons on either side of the
AI Pipe/Valve - push the two buttons and pull the pipe up and off and make sure there is clear - if there's a blockage remove it and
continue with the blockage check to ensure that the entire machine is clear)
(iii) Refit the internal hose on the bottom of the machine between the wheels and make sure it isn't torn and has no holes in it and
that there is nothing clogged inside it - to refit the hose: Pull it off where it sits next to the wheel first - make sure that the
gray piece of rubber is still on the hose (if it isn't, pull the gray piece of rubber off the hole and reconnect it to the hose by
twisting it back on) - next, twist the hose off where it connects to the brushbar - inspect the hose and make sure you don't have any
holes in it - put it back on by twisting it onto the side of the brushbar first - then line the gray piece of plastic end up with the
hole next to the wheel and push and twist it back over the hole. Bring the machine back upright and test it

2) To check for blockages in the wand. Remove the:
(i) U-Bend (stand behind the machine and look next to the right-hand-side wheel, it's attached with a rectangular clip next to the
long gray hose - push the clip and pull the U-Bend off, make sure its clear - if there's a blockage remove it and continue with the
blockage check to ensure that the entire machine is clear)
(ii) Wand - take the wand off the back of the machine - put one hand on the wand handle and one hand on the gray hose - pull the
handle and push the gray hose down, you'll see a metal rod being exposed, push the hose until it clicks into place - press the
half-moon shape button with a picture of a lock on it (found on the solid gray plastic end of the flexible hose) and separate the wand
competely - point the wand into the air or at a source of light (please don't point it at the sun) and look through the metal rod part
- the handle is bent but you should still see some light coming through the other end - if you don't, there is a blockage in the wand
- use a long object like a stick or a metal hanger to remove the blockage
(iii) Hose - no need to remove it - just stretch it out and make sure that there are no dark spots in the hose (those would be
blockages) - you can also through the top of the hose - if you don't see the ground at the bottom there is a blockage in the hose

3) If no blockages are found on the machine at all:
(i) wash the filter in cold water and leave it out to dry for at least 24 hours
(ii) blow out the cyclone from the bottom (open the door on the bin door - you can now look into the cyclone) - blow it out with an
air compressor or a leaf blower
(iii) Wipe all the small holes off on the cyclone with a dryer sheet
When the filter is dry, test the suction again. If there still is no suction on the machine, call the Dyson Helpline, they'll set you
up with a repair with the closest authorized dealer in your area.

Use the upholstery brush supplied to unclog the perforations on the Dyson filter; the clogged holes don't impede on suction so you dont have to worry about this. It can be annoying however when you see it.

SOURCE: I have a Dyson vacuum. The vacuum won't stay

My vacuum had this exact same problem, but was out of warranty because it was remanufactured. Thankfully, it's a very quick, five-minute fix.

  1. UNPLUG The Vacuum!
  2. Remove the cannister.
  3. Extend the handle and remove it.
  4. Remove the two torx (T-15) screws behind the power button, where the handle normally stows.
  5. There are four tabs holding the front plate containing the power button on; use your screwdriver to release them.
  6. Gently pull the front plate off.
  7. The switch on the right is the power button. Remove it, try clicking it a few times; if it sticks, great! Replace it and reassemble, otherwise you'll need to replace it.

I hace a dyson portable unit and took it out this morning began to vacum and the unit began pulsating. I placed it back on the charger for an hour and tried it again, same problem?


Hello, this is Ava with Think Crucial.

There are a number of reasons why your Dyson cleaner is pulsating off and on. First, it maybe due to a battery of the unit. Make sure that the power cable is properly plug to the power and seated properly from the unit while charging. If you find that the battery isn't charging at all, you may need to replace the battery. Second is to check the MAX button of your cleaner. If the button lights up and flashes when your Dyson keeps on pulsating, press and hold the power button and depress the MAX button to turn off the function. You may need to do it for a few times to get the hang of it. Third is to check for any blockages or clogs in the attachments. Look down through the tube and check to see if there are clogs on the sweeper end or if the roller is tangled up in fibers. Clean the roller brush are if it it's necessary. You may need to empty the dust bin of your unit as debris can build up in hard to reach places. Lastly, cleaning the filters may fix the pulsating of your cleaner. Remove the filter and rinse it with cold water and air dry it for 12 hours. Don't use detergent when washing your filters. If the pulsating doesn't go with the given quick fix, I suggest to contact Dyson for further assistance on this.

Why does pressure release keeps going off in canister on dyson dc24 when turned on


Remove the filter in the ball and the filter in the hood. Turn on and if valve still pops off then you have a clogged hose or tube. If it's ok then one or both the filters are choked and require cleaning.

Hi its Darran at Dyson.

The first check would be to see if the brush bar is turning when the machine is switched on and in the vacuuming position. To do this, release the head and lie the machine on its side. Switch it on and check the brush bar making sure long hair and fingers are kept out of the way.

If the brush bar is turning, you will need to check the machine thorugh for blockages and clean the pre filter as these are the most likely cause of a loss of performance.

If this does not resolve the problem or if the brush bar is still not turning, please contact our Helpline on 0800 298 0298 (UK) or 1866MYDYSON (US).

1 Answer

There is a - and i will call it - a relief valve on the top front of the canister that pops when the handle is released to vacuum - i have cleaned everything like the manual says but did not work -


Im not sure about this relief valve - if its a valve that has a flipable catch on the back of the handle its not always supposed to pop open. Perhaps you could be a bit clearer where the valve actually is? Older Dyson models have a valve on top of the handle where further small cleaning attachments can be fixed onto clean. If its clogged then a wire brush will need to be inserted into the handle to clear the clog thus making the attachments **** up dirt.
