Hi, My Dyson DC07 All Floors recently started making a horrible loud plastic grinding noise but only when the machine is leaned back to engage the brush bar. I thought the clutch assembly had failed and replaced it. Unfortunately this has not fixed the problem. The brush bar seems to be turning freely so I'm looking for any other ideas? Thanks, Chris.
I had the same problem with mine, I took it to a repair shop. The problem is where the belt passes through from the brush and goes inside the machine. Move the belt over a bit and you will see that a plastic guide has been bent over and is pressing onto the brush, which causes the noise. Just bend it straight again and it stops.

Hi. You either need A new clutch or clutch belts need replacing. Its a lot to describe so try this it has manuals on how to do the job.

You need to clean your roller and replace the clutch assembly that drives the belts. poorly designed vacuum with many flaws.

Thanks for the advise I ended up disassembling the unit again and noticed one of the plastic guides on the inside of the brush housing that lines up with the belt had worn away. I think this may be causing the belt to get jammed when its turning at speed. I have ordered a new brush housing they are not expensive and its the only part that appears slightly damaged. Will let you know how I get on
This actually ended up being the bearings inside the brush bar on the side nearest the belt. You can diagnose this by removing the brush bar and shaking it. If the bearings have failed you will hear the ball bearings rattling around inside the brush bar housing (this is not normal). The bar appears to rotate freely until there is pressure on it, when it picks up speed the friction from the failed bearings will cause it to seize up and the clutch will slip making that horrible noise. After replacing the brush bar everything was fine. Hope this helps.
