Using this Samsung washer lint filter is easy. First, locate the front of your washing machine. You'll find a spot either behind the kick panel or a small flap. Unscrew the area and then screw in this lint filter. When it comes to maintenance, it's a good idea to check the filter regularly, especially after a few loads of laundry. If it's full of lint, simply remove it and clean it under running water. As for the note, make sure you double - check your washer's model number. Since this isn't the only filter used in Samsung washers, using the wrong part might not work well for your machine. If you have any doubts, give us a call with your full model number before making a purchase.
