Using this lower spray arm is easy. First, make sure your dishwasher is turned off and unplugged. Then, carefully remove the old spray arm. It might be held in place with a clip or a screw. Once removed, take your new dark grey lower spray arm and install it in the same position as the old one. Ensure it's properly secured. When using your dishwasher, avoid overloading it as this can put extra stress on the spray arm. For maintenance, check the spray arm regularly for any signs of wear or blockages. If you notice food particles or debris, clean it gently with a soft brush. If the spray arm doesn't spin properly, it might be time for a replacement. And remember, if you have any questions about this part or its compatibility with your dishwasher, don't hesitate to reach out to us.
