How to Clean the Dishwasher Drain Filter?

Some dishwashers have self-cleaning filters. This drain filter acts as a kind of garbage disposal for food particles. However, you no need to worry about build-up of dirt with these. Manual filters are more common for cleaning. If you don't know what type of filter do you have a dishwasher, check the manual or take a look at the machine itself. You can find the drain on the bottom of the machine by removing the lower rack. If you have manual filters, they are cylindrical and you can see arrows that can indicate their removal.

  • Remove the drain filter from the lower rack of the dishwasher.
  • Wash the filter with soapy hot water in your sink. You can use a bottle brush or toothbrush to clean all the interior surfaces.
  • Rinse the filter thoroughly and allow it to dry.
  • By using a damp cloth or sponge, you have to clear any food or debris from the dishwasher drain before replacing the filter.
  • Reinsert the cleaned dishwasher drain filter and make sure to lock it in place.

Cleaning of drain filter is enough to eliminate the source of bad smells. If it solves the problem, your machine is ready to get back to work.
