    Hi there,

    I also have this problem, but you have to pay for the instructions on how to fix it on the site suggested. Does anyone have the disc or know how to fix the issue with the suction/relief valve?

Hi,

I had the same problem with my DC08. What I had found is that cleaning the main washable filter will remove the problem. I have a log fire at my place and I have found that the vacuum does not like the dust from the fire. Even though I sweep up any ash before vacuuming, the problem still exists. At times over winter I will have to clean the filter every week as it doesn't take long for the relief valve to start to open. Over summer, I have no relief valve problems at all. Hope this helps.

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.

Rear canister valve


Hi there Coire, it's Jack at Dyson.

The valve you've described is the suction relief valve. This will open when something is restricting airflow through the vacuum cleaner.

In normal use, we recommend washing both filters at least once a month, as shown in the video above. Use cold water without detergent, and allow at least 24 hours for both filters to dry completely somewhere warm before replacing them in the machine.

If you find this doesn't resolve the issue it's likely your machine has a blockage - to locate and remove this, please follow the steps shown in our online Support guide: http://www.dyson.co.uk/support/dc24/dc24-multi-floor/my-machine-is-not-working/machine-not-sucking-picking-up-as-well-as-usual/how-to-wash-filters/check-suction

For any further advice after you've given this a try, please contact our experts directly by calling the Dyson Customer Helpline on 0800 298 0298 (UK), 1-866-693-9766 (US), or 1-877-397-6622 (CA).

Can i reverse suction on DC08


Hi there,

Your DC08 is not designed to be used as a compressed-air blower, and we'd advise against attempting to use it for this purpose as it may cause damage to the machine.

If this is not what you meant, please email me with further details at askdysonUK@dyson.co.uk, as I may be able to help.

Alternatively, if you'd prefer to speak to one of our advisors in person, please call our Helpline on 0800 298 0298 (UK), or 1-866-693-9766 (US).

Best wishes,

Loss of suction in dyson dc08


Hi there,

If your DC08 doesn't seem to be picking up as well as usual, there may be a blockage in the machine. The filter may also need a wash.

The easiest way to locate and remove any blockages is to follow the steps shown in our online support guide:

http://support.dyson.co.uk/support/dc08/dc08-standard/my-machine-is-not-working/machine-not-sucking-picking-up-as-well-as-usual/check-the-floor-tool

In normal use, the filter needs to be washed at least once every 3-6 months, as shown in the video below. Use cold water without detergent, and allow at least 12 hours for the filter to dry completely before replacing it.

This should resolve the issue, but if you'd like any further assistance or advice, please call us on 0800 298 0298. Our Helpline is available from 7am until 10pm, 7 days a week.

Loss of suction


DYSON DC08 ROOTCYCLONE Loss of suction problem.

I had this exact problem and solved it.
No offense to Dyson Customer Service, but that advice isn't nearly enough to explain how to clean the cyclone. I used to work in Customer Service for an electronics company and I never let anyone down because of clear and precise instructions.
So, here is my advice:

NOTE:
Remember properly where all the screws go and how the bits fit together. It's important so that there is no loss of suction due to improper replacement of parts.

Step 1
Remove the canister from the vacuum cleaner and take off the clear bottom bit - the container for dirt. Clean that out well, you can use water but MAKE SURE IT DRIES COMPLETELY.

Step 2
Pop off the conical bit at the bottom of the cyclone. It isn't held by any screws, just nudge it out of place.

Step 3
You will see three holes amongst the vacuum entry holes. These three holes have screws in them. Unscrew those.
The type of screws used are star-like, but I used a small flat-head screwdriver. Make sure the edges of the flat-head fit perfectly into the edges of the slot on the screw. This prevents grinding and damaging the screw.

Step 4
Turn the canister over, the grey handle conceals three screws. Two on top and one beneath the bottom of the handle at it's base. When you remove the two screws that are visible, you can gently pop off the handle from the canister. First pull the handle up slightly, then the hook unlocks at the base, then push the handle away from the air inlet hole.

Step 5
Turn the canister over again. The bit where you removed three screws should come off easily. Beneath that, you will see two more screws, holding the top bits together. Remove those screws.
Then, all of the cyclone is loose and you can clean each bit separately. Again, you can use water, but let it dry very well.

Step 6
Put it all back together.

Pressure relief valve opens


Hi.

If the hose works ok then you have A blockage in the section of the machine that goes from the brush roller to the wastebin.

Just remove the soleplate under the machine & check all the airways working back to the wastebin. definately check removeable inspection ports you will probably find omething in them blocking the airway.
