Samsung Dust Sensor Under-Response

Auto mode does not increase suction when vacuuming heavy dirt.

This repair may involve working with high voltage components or water connections. Always unplug the appliance before removing any panels.

If you are not confident in your ability to perform this repair safely, we strongly recommend contacting a professional technician.

Possible Causes

Dirty dust sensor window, Faulty dust sensor, Blocked airflow near sensor, Sensor calibration drift

Safety first: Remove the battery before cleaning internal sensors.

Clean sensor area: Locate the dust sensor near the cyclone and gently clean its window with a soft brush or compressed air.
Ensure proper assembly: Make sure the cyclone and bin are correctly installed so air flows past the sensor.
Test in manual high mode: If manual high mode works, the suction system is fine and the issue is sensor-related.
If auto mode still does not respond: The dust sensor module may need replacement by a technician.
