Is your dishwasher not cleaning your dishes as well as it used to? It may not be the new detergent you’re using. Dishwashers have filters that filter out food particles and recycle the water through the cycle. When these filters become clogged the dishwasher can’t work as it was designed to. Some manufacturers recommend monthly cleaning, while others say a couple times a year. It really depends on how often you run your dishwasher, and how well you rinse your dishes before loading them in your dishwasher. If you are unsure of when your dishwasher filter was last cleaned, or it has never been cleaned it’s a good idea to check it out.
