Using this Westinghouse detergent drawer screen is easy. Just insert it into the left - hand side of the detergent dispenser in your compatible Westinghouse top loader washing machine. Before use, make sure your machine is turned off and unplugged. When it comes to maintenance, you can remove the screen every few months and clean it under running water to prevent any blockages from detergent residue. As a reminder, this part is only for the left - hand side, and the right - hand conditioner screen insert and dispenser tray are not available. If you're not certain if it fits your washing machine model, reach out to us with your model number before making a purchase. And don't worry, it comes with a full guarantee, so you can use it with peace of mind.
