How to Clean Your Dishwasher Properly

Improve Performance and Prevent Odors

Introduction

Many homeowners assume dishwashers clean themselves, but over time, grease, food particles, and mineral buildup can affect performance. Regular cleaning helps your dishwasher run efficiently and prevents unpleasant odors and drainage problems.

Why Dishwasher Cleaning Matters

Food debris and soap residue accumulate in filters, spray arms, and drain areas. Without cleaning, these materials restrict water flow and reduce cleaning effectiveness. Buildup can also lead to slow draining and foul smells.

Cleaning the Dishwasher Filter

Start by removing the bottom rack to access the filter. Most filters twist or lift out easily. Rinse it under warm water and use a soft brush to remove debris. Avoid harsh scrubbers that can damage the filter.

Cleaning the filter every few months improves water circulation and prevents clogs.

Cleaning Spray Arms and Interior Surfaces

Check spray arms for clogged holes. Use a toothpick or soft brush to remove debris that blocks water flow. Wipe down the interior walls, door seals, and detergent dispenser with a damp cloth and mild cleaner.

Pay special attention to door gaskets, as trapped moisture and debris can cause odors.

Running a Cleaning Cycle

Place a dishwasher safe cup filled with white vinegar on the top rack and run a hot water cycle. Vinegar helps dissolve grease and mineral deposits. For deeper cleaning, follow up with baking soda sprinkled along the bottom and run a short hot cycle.

How Often to Clean Your Dishwasher

Light cleaning every month and deep cleaning every three to six months helps maintain performance. Homes with hard water may need more frequent attention.

When Plumbing Issues Are the Cause

If cleaning does not resolve drainage or odor problems, the issue may involve the drain line or garbage disposal connection. A plumber can inspect and correct underlying plumbing concerns.
