Scrub the door seals, edges, and bottom frame using a damp melamine sponge. Focus on areas where grease, soap scum, and hard water buildup collect.
Remove the bottom filter by twisting it counter-clockwise. Rinse under hot water and scrub with dish soap and a toothbrush, then reinstall it.
Remove the vent cover on the inside of the dishwasher door and scrub away hard water stains and mildew buildup.
Spray vinegar inside the dishwasher and sprinkle baking soda across the bottom. Lightly scrub visible stains as needed.
Place a dishwasher-safe bowl filled with white vinegar on the top rack. Run a full high-temperature wash cycle.
Wipe down the stainless steel exterior with a soft cloth to remove fingerprints, smudges, and water spots.

Use vinegar only occasionally, as frequent use may wear down rubber seals over time
Always make sure the filter is fully reinstalled before running a cleaning cycle
Deep cleaning every 1–3 months is usually enough for most Whirlpool dishwashers
If odors persist after cleaning, check the drain and filter area for trapped debris
Avoid overloading the dishwasher, as poor water circulation can reduce cleaning performance
Cleaning the vent cover can significantly improve drying performance
Always run a hot cycle for best results when deep cleaning
