Why Is My Dyson Not Working Properly. Do not use mineral oil for this. The brush bar may not spin if the cleaner head is set too low.
A flashing blue light indicates that there is no power and the battery needs to be charged for a minimum of 35 hours. In this case problem is from battery when flashing blue light speed is higher than normal time flashing blue light that indicates need to charge. If it is please dont attempt to use your machine and contact the Dyson Helpline.
I pulled the power head apart cleaned it of all the hairs etc and most importantly oiled the bearings on both ends of the small motor and the bearing end of the brush.
If the charging station of your Dyson vacuum is a wall-mounted model you can try mounting it. My Dyson worked perfectly again straight away after doing this. I used Lanolin oil which I think will not attract dust. Some Dyson vacuums have removable cleaner heads and if the head isnt locked into position the motor that powers the brush bar wont operate.
