Why does my does my dishwasher smell bad?

If you're getting a bad smell coming out of your dishwasher it's because with every cycle, food particles and debris get stuck in the filter. Bad dishwasher smells can be fixed in a few easy steps.

How to clean a smelly dishwasher?

If your dishwasher smells, you should clean it thoroughly by following these tips:

Use the Bosch dishwasher cleaner a few times a year to remove greasy residues. Simply add one box of cleaner to the bottom of your dishwasher and run the hottest, longest cycle.

To remove hard water deposits and limescale buildup, use the Bosch descaler a few times a year. Simply add one box of descaler to the bottom of your dishwasher and run the hottest, longest cycle. Once that cycle has finished, run another wash cycle.

Clean the filter regularly, it can be found at the bottom of your dishwasher. Review your owner's manual to learn how to remove it. Download ithe manual here if you don't have a copy of it. After removing the filter, clean it by running it under water with soap and a soft brush. To learn more, view our 'How to Clean Your Dishwasher Filter' video on our How-to Video page
