I have a Hoover 31.0 12 amp wind tunnel vac model # u6625-900. It has a green and red light that says clean and dirty. Usualy the green light is on until it needs to be cleaned. Well now the red lights on all the time. There must be some kind of flow switch inside. can someone help me with this please.
