Using this fine mesh central filter in your dishwasher is a breeze. First, make sure your dishwasher is turned off and unplugged for safety. Locate the old filter in the central area of your dishwasher and carefully remove it. Then, take this new filter and place it in the same spot. Ensure it fits snugly. When it comes to maintenance, it's a good idea to clean the filter regularly. You can do this by removing it and rinsing it under warm water to get rid of any debris. As for the note, although it's similar to the white filter, don't assume they're the same. Always double - check the size and look at the photos if you're in doubt. If you're not sure if this part is suitable for your dishwasher, don't hesitate to reach out to us with your brand and full model number before you make the purchase. And with our full guarantee, you can use it worry - free.
