I have a Windsor SR12. When I Switch the power on, the "Check Brush" and "Bag Full" lights illuminate for about 1/2 second then turn off. The motor does not run. What is going on?

The problem was a sticking switch that was not being reset. The vacuum on/off switch mechanism is comprised of two switches. One is the main switch that turns the vacuum on and off. The second is a shut off switch that gets tripped when the full bag sensor is engaged. This second switch is supposed to get reset when you push the on/off switch on the outside of the machine. The full bag shutoff switch was stiff and it, therefore, was taking a couple of presses of the on/off switch to move the shutoff switch back into the running position.

Either there is something wrong with your switch. Which it doesnt sound like it. Take it to your dealer or call another one it sounds like the control valve needs to be replaced. I am a dealer 1-866-966-9350.

SOURCE: windsor sensor says bag is full when its not

Are you vacuuming up fine particals like pet dander or just large amounts of regular dust? Also when was the last time you replaced your filters?

Just some sugestions.

SOURCE: 'Bag Full' light indicates at 1/3 bag

The sensor is a small hole into the vacuum chamber. It moves the alert system as vacuum inside the unit builds up.

The filtration, built into the bag, is getting filled up and creating a higher vacuum inside the unit, giving a false reading. The only ways to eliminate this are to give the bag a shake to clear some of the dirt out of the filter, try to pick up coarser dirt first or buy generic bags-without the filtration.
