Pressure relief valve opens

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 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

Vacuum Cleaners require AIr-Flow. Your machine is not getting any air-flow. The noise you hear is a valve opening up to prevent your machine from overheating and burning out the motor.
You probably have an obstruction somewhere in the machine. Dysons are kind of known for that in the vacuum cleaner world.
Check all air channels and clean them out. If that fixes the problem you still might have issues that caused it to clog up.

I posted the part second because it takes 24 hours to complete it.
Be sure you wash your Washable Pre-filter. It needs to dry for 24 hours. Never put it back in the machine wet.

Once it is completely dry reinstall the pre-filter and your machine should be back to normal operating functions.

Let me know f this helps.

How full is the bag?

Dear Chris, I'm sorry to hear you're having difficulties with your DC07 Animal. Like most Dyson cleaners, your DC07 is equipped with a safety device which shuts off the cleaner if it starts to overheat. This is often due to a blockage, or because the filter needs a wash. Although you've already checked for blockages, you might want to take a look at our online support guide, to make sure you haven't missed anything: http://www.dyson.co.uk/support/help.asp?article=4&product=DC07-ANIMAL under normal use, this should be done at least once every 3-6 months. Use cold water without detergents, and allow up to 24 hours for the filter to dry completely before replacing it. Some discolouration of the mesh part of the filter assembly is normal, and will not affect performance. By clearing any obstructions and washing the filter, you should be able to resolve your issue without further assistance. However, if you've followed these steps and are still concerned, I'd encourage you to get in touch with us directly. You can call us free on 08002980298 (UK), or 1866MYDYSON (US). One of our experts will be happy to run through some troubleshooting over the phone with you and recommend the best course of action. Kind regards, Jack Dyson Online Customer Support

Hello,

There are 3 different filters on this particular model. Two of them are foam, and as washable, the 3rd is a HEPA filter that's located on the back and is not washable, but needs to be replaced once a year.

The most important filter, and the one that most people are not even aware of, is located directly underneath of the dirt cup. Directly under the dirt cup you'll see a black tray that says "pull". Pull this tray out, and you'll find a square shaped washable filter. Simply remove this filter and rinse it under water until it's clean. Make sure to let the filter completely air dry before reinstalling it in the vacuum and using the vacuum again.

The second foam filter is located directly above the dirt cup. Remove the dirt cup, and in the clear plastic housing that's directly above the dirt cup you'll find a circular colored plastic piece. Reach your hand up there, and unscrew this plastic part while pulling downward. You'll find a circular shaped filter that wraps around this plastic piece. This filter may also be washed the same way as the square shaped one, again just make sure that the filter is completely dry before using the vacuum again.

The HEPA filter is actually on the back of the vacuum in a grate that pull down to open it and remove it. This filter needs to be replaced only, and can not get wet.

The foam filters can be washed several times, but will sooner or later need to be replaced, as they will start to deteriorate after a few washings.

If you need to purchase these filters, here are direct links to all of the filters on your vacuum cleaner.

Square Shaped Pre-Motor Filter Bissell Part 203-1073

Circular Shaped Bissell Upper Tank Filter 2031085 Pre-filter Lift Off Series

There is a filter above the chamber that you have to remove and clean. If you look closely in the top where the chamber snaps it there is a small lever that opens up to provide access to two filters, one is made of foam and the other is a screen that will require washing and drying before you put it back in. Hope this helps.

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.

You need to clean the debris channel. Put the machine on a waist high flat surface open it and remove the dirty water container. You will see three vertical screws which lock the scroll above the motor to the clear plastic panel at the front of the machine. Open these screws and remember which one belongs where. To the left of the scroll, there is a black horizontal screw which should also be removed. If you look closely, you will see the right hand of the first three screws (brushes face to your right hand) has also released the plexiglass (clear plastic screen where you see the dirt and soap flowing at the left side. Now put the machine on its side and look at the front edge of the plexiglass just ahead of the brushes. There are two screws which have to be removed - one on each side and bingo the plexiglass shape lifts clear. Clean out the muck, check the scroll channel for similar muck and reassemble.

The muck is plugging the dirt path and fooling the red float that the tank is full.

Re assemble the reverse of the disassembly procedure. Do not use a power screwdriver as you will likely shear the screw heads.

Good luck,

AMSW
