Dishwasher Installation questions, answered by experts

A dishwasher filter should be replaced every five years, depending on the manufacturer's recommendations and the frequency of use. The exact timing can vary based on factors such as the hardness of your water, how well you rinse dishes before loading them, and how often you clean the filter. Regularly inspect the filter for signs of wear and tear or damage. If the filter appears worn out, damaged, or excessively clogged despite regular cleaning, it should be replaced sooner.

In most cases, you can access one side of the hose from below your sink, as it usually ties into the same drainline that your sink uses. Otherwise, you may need to pull the dishwasher out of the counter to access it.
