Isn't the LEDs on the adjustment panel suppose to change when I adjust the suction power? When I start the machine, LED #2 from the bottom is lit. The machine seems to work on max power. When I push the - button, the power decreases and the single LED goes out. When I push the + button, the power increases again and the single LED is lit. Shouldn't the other LEDs ligt up when the power increases?
