Vacuum: Green light always on

If the green indicator light won't turn off, unplug the vacuum and clean the sensing lenses with a fresh, dry lens cloth. Don't use a wet cloth—water ruins the lens coating. If the problem continues, check the wiring connections. If the wiring connections are sound, it's likely that the PC control board for the dirt sensing system has failed and must be replaced.

These repairs may help solve your Vacuum problem:

Clean the dirt sensor

Dirt sensor

The dirt sensor detects the level of dirt and debris passing through the suction hose to the collection bag. Clean the dirt sensor when dirt and debris coat the lenses and the sensor can't accurately detect dirt level.

Replace the dirt sensor control board

Dirt sensor control board

The dirt sensor control board receives signals from the dirt sensor and sends signals to the dirt sensor display. Replace the dirt sensor control board if it doesn't properly detect dirt sensor signals or doesn't send display signals to the dirt sensor display.
