Using this dishwasher wash filter is a breeze. First, make sure your dishwasher is turned off and unplugged. Then, locate the old filter in your dishwasher. It's usually at the bottom. Remove the old filter carefully. Now, take your new filter and place it in the exact spot where the old one was. Make sure it fits snugly. Once it's in place, you can plug your dishwasher back in and turn it on. When it comes to maintenance, it's a good idea to check the filter regularly, say once a month. Look for any food particles or debris that might be stuck in the mesh. If you find any, simply remove the filter and rinse it under warm water. This will keep it working efficiently. As a note, since this part is no longer available from the manufacturer, handle it with care. If you have any issues with it not fitting or not working as expected, contact our customer service right away as it's fully guaranteed.
