How to Clean the Whirlpool Dishwasher Interior
Don’t just clean the dishes — take the time to ensure the dishwasher interior is clean too. When it’s time to clean the dishwasher, keep in mind the following cleaning tips for dishwashers.

Dishwashers should be cleaned approximately every 30 days for optimal performance. Using affresh® Dishwasher Cleaner every month will help keep your dishwasher from filming and spotting, and the interior clean and free of odors.

Extremely hard water mineral deposits can cause damage to your dishwasher and make it difficult to achieve good cleaning. A water softener is strongly recommended if your hardness is 15 grains or more.
