With power on in upright position suction goes to the wand as usual, however when the vacuum goes into the sweep mode there is no action in the cyclone, no suction at the beater bar and back pressure coming from the top of the cyclone housing vent. The beater bar switches on and off OK. and the suction to the wand is OK too.
I have dismantled the cyclone housing and cleaned it out, I have also washed the pre-filter.
There is still no suction at the beater head and the cyclone has no action.
This problem has just started, until then the cleaner was working fine.
Your filter is dead. fit new cyclone filter

Hi.
You will have A blockage in either the wand or hose, completely remove them from machine the hose unclips at the bottom back of machine,
Now switch machine on with this removed if machine sounds ok then remove the blockage from hose or wand.
If machine still poor suction & noisey with hose & wand removed check the (U) shaped inspection port for blockages.
Let me know how you get on.

It sounds like the same problem I was having. I had loss of suction through he hose then all of the air was coming out through the vent/valve on top of canister. If you are looking at your dyson from the back, look at the bottom. You will see a purple plastic tab on the bottom left. That allows you to remove the plastic u-shaped hose that goes from the hose to the bottom of the dyson. I just removed that and found it was completley blocked. I removed it and the dyson has no loss of suction orair through top valve/vent. I hope this helps. I never post but i'm just excited that I got my dyson working perfectly again.

I have finally fixed my sister's dyson dc 15 beater bar problem. It was just 2 tiny broken wires connect to circuit board lead to the beater bar. The wires broke where they go through the black rubber gommet. You need a torx screwdriver tx 15 to remove 2 plastic covers to access the wires. When looking at the front of the vacuum, the gray covers located on the right side of the vacuum. 1 big cover with a black rubber gasket and other small gray cover is on the rotating ball area.
This my new year resolution is to warn people not to buy Dyson vacuum cleaner ( Junk) design to break down! Shame on you Dyson!!!! Save your money find good old vacuum cleaner with metal parts.
OLD IS IN NEW IS JUNK!
Happy New Year!

they will be a blockage some where in the wand simply take apart tube and clean
If that is closed check the long metal wand. Disconnect from the beater bar head and check the whole length of the wand and look into the beater bar head opening for something plugging it.
