Question about Vacuums
So... we plug in the Dyson, see? and it starts up just fine and den? This thing called a motor protection valve starts whistling and sucking. What's up wid dat? My wife's hea yammerin' at me, I don't know what to do! Help!!!! I looked at the filter and it wasn't too dirty, the thing's only a couple months old. I dusted it off and put it back together and still the same thing!!
Any ideas guys and maybe girls? Tanks in advance for your help.

We had the same problem and located a big clog at the base of the flexible hose, where it goes into the U-bend attachment. See the DC14 Owners Manual, page 11, Item C for a picture. If youve already thrown out your manual, its available on the Dyson website. Theres a white tab button which allows the U-bend to slide out for cleaning. There are other places where clogs can occur (again, see the manual), but this is one of the more likely trouble spots.

The motor projection usually comes on when the motor overheats. A clog maybe causing this. There a number of pieces to take of and check for a clog. You also have warranty on this, if you can't figure it out, take in to a warranty repair shop for repair.

I had the same problem, and various people, including professionals recommended new parts & even a new motor at 1 point. I was extremely frustrated as I have a fairly small house & it's not as if the vacuum was being used 24/7. Eventually after a lot of investigating I discovered there was a large blockage. I removed the flexible hose & below that there is a 'u-bend' small, removable pipe (check owners manual). I removed this & even though I had checked it before, there was a blockage which had been causing the noise & loss of suction. I hadn't seen it before as the pipe is curved & the blockage was in the centre where I could not see. After poking and prodding a large ball of gross stuff came out & after assembling the vacuum again it is working perfectly fine and didn't cost me a penny :) no more high pitched, deafening whine & suction back to normal. Always worth remembering to clean the brush head as well as hair etc can get wrapped around it & cause problems. I hope this helps anyone experiencing the same problem.
