You very likely have a defctive control valve under the dial on top of the vac , or a kink or blockage in the tiny pressure hose that feeds the air from the throat of the vac or the back of the bag chamber against the two sides of the rubber diaphragm inside the valve. You can inspect the tiny hose ports for blockage and clean them with a fine piece of wire. To access the control valve you will open the bag chamber door and slide the bumpers forward with their internal locking keys with a pair of pliers. Once removed the body will open like a **** shell front to back. The control valve will likely have a crack in its threading and can only be replaced with a genuine part available at an AERUS Electrolux store. The fix is a most often a new valve. This vac is the RUBIKS cube of all vacs. It reassembles with ease when all wiring and tabs are perfectly aligned, so open slowly,upside down , wheels up , mark your wiring and take your time reassembling. When it all clicks EASILY together without the bumpers, you have it done right
