Clean the Filter

Most dishwashers have a removable filter at the bottom:

Use a soft brush to remove debris

Replace securely

Run a Cleaning Cycle

Monthly cleaning removes grease and mineral buildup:

Run on the hottest cycle with an empty dishwasher

For stubborn buildup, sprinkle baking soda on the bottom and run again

Disconnect inlet hose

Clean the screen

Reconnect and test
