Why do dishes still smell after being washed in a dishwasher? Causes & solutions

Have you used your dishwasher only to find your dishes still have an unpleasant odor? This is a common issue and usually easy to fix. Let's look at the causes and solutions.

1. Dirty filter — the number one culprit

Food debris accumulated in the filter will decompose over time and produce odors, which then transfer to your dishes. Remove the filter at the bottom of the dishwasher and rinse it under running water once every 1–2 weeks.

2. Moldy door gasket and crevices

Water and debris trapped in the rubber gasket around the door create a breeding ground for odor-producing bacteria. Wipe the gasket and crevices dry after every few washes.

3. Not scraping off food scraps before loading the dishwasher

You don't need to rinse thoroughly, but you should scrape off bones, shells, and large food scraps to prevent clogging and odor buildup in the machine.

4. Using too little or the wrong detergent

Insufficient detergent prevents grease from being fully broken down, leaving behind odors. Use the correct dosage of specialized dishwasher tablets for each wash cycle.

5. Hard water leaving residue

Limescale from hard water not only causes odors but also makes dishes appear cloudy. Add dishwasher salt and rinse aid to soften the water, help dishes dry quickly, and eliminate damp odors.

Quick odor removal tip

Periodically run an empty cycle at a high temperature to clean the interior of the machine. Your dishes will be fresh-smelling again.
