Dryer displays 'Check Filter' or filter icon and may have poor drying performance.

Safety: Turn off power before removing panels or ducts.

• Clean lint filter: Remove the filter and wash with warm soapy water if coated with fabric softener residue. Dry completely before reinstalling.
• Vacuum filter housing: Use a vacuum with a crevice tool to remove lint from the filter slot and surrounding area.
• Inspect exhaust duct: Disconnect and clean the entire duct run to the outside. Ensure strong airflow at the exterior vent.
• Check airflow sensor (if equipped): Some Samsung models use a pressure switch or sensor; inspect tubing and connections for blockages or disconnections.
