Using this Samsung lint filter is a breeze. First, turn off your washing machine and unplug it for safety. Then, locate the lint filter area in your Samsung top - load washer. Usually, it's near the bottom front or side. Carefully remove the old filter and replace it with this new one. Make sure it fits snugly. When it comes to maintenance, check the filter regularly, especially after each few washes. If you notice a lot of lint trapped in the plastic mesh, simply rinse it under running water until it's clean. Let it dry completely before putting it back in the washing machine. As for precautions, always ensure the washing machine is off and unplugged before handling the filter to avoid any electrical hazards. And remember, this filter might fit other models too, but double - check the compatibility first. You can rely on the full guarantee we offer, so if you have any issues, feel free to contact us.
