Chosen Solution
I quarter turned the screws and exposed the roller brush to remove built up pet hair. When I reassembled it, the DYSON DC14 turns on but the brush roller won’t rotate and their is no bottom suction. The extended wand has suction all of the time but not the power head. I may have disoriented the endcaps on the roller bar and would like to know proper placement. Also, why no suction there now and how do I fix that? Debra R
ruthdebra55 , Sounds like the hose/channel to the power head may be plugged, remove power head brush and see if suction port clogged and also make sure canister is locked into position correctly. Find below a guide on the power head that shows orientation. Good luck. I hope this helped you out, if so let me know by pressing the helpful button. Dyson DC14 Brush Bar Replacement
