Vacuum: Red light always on
If the red indicator light won't turn off, clean clogs from the hose and internal suction air path in the vacuum If the problem continues, 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.
These repairs may help solve your Vacuum problem:
Replace the vacuum suction motor
The suction motor rotates the fan that creates suction by moving air from the intake at the cleaning head to the dirt collection chamber. If the motor doesn't create suction or doesn't run at all, replace it.
Replace the vacuum hose
The vacuum cleaner hose is constructed of reinforced vinyl. It sometimes has wires integrated into the hose. If the hose is torn or the integrated wires are broken, replace the hose.
Replace the vacuum bag
The vacuum cleaner bag collects the dust and dirt that the vacuum sucks up. It also helps filter the exhaust air. Replace the bag when it's full, torn or damaged.
Clean the 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
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.
