If you get a sewer smell when you are using the dishwasher on a kitchen sink, it often means that the dishwasher filters needs to be cleaned or there is a blockage in the vent or the drain of the pipes inside the wall. Bad odors within dishwashers is a common occurrence and can develop overtime through regular use.,
The drain hose from your dishwasher into the plumbing under your sink needs proper flow. If the hose is bent or turned, it causes the dishwasher's wastewater to enter back into the dishwasher basin. A bent drain hose may even cause a new dishwasher to smell bad.
Therefore, pouring an odor neutralizer directly into the dishwasher will likely have little effect. Another solution is to spread one cup of baking soda over the bottom of the dishwasher and leave it overnight. If you then run a cycle in the morning (with the dishwasher empty), it should clear away the odor.Jul 7, 2021
Dishwasher odours are generally caused by a build-up of trapped food particles or grease. They can clog the filters, spray arm, drain hose and other little nooks around your dishwasher.Feb 15, 2018
Pour 1 cup of distilled white vinegar in a bowl, and put this on the top rack of your dishwasher. Without adding anything else, run a full cycle in your dishwasher. This will wash the entire inside with vinegar, so the light acid can clean off any remaining food residue.Jun 26, 2015
