Why is my vacuum cleaner's red light always on?

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 vacuum 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 vacuum 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.
