How to clean the filter on a Bosch dishwasher?

Published in Dishwasher Filter Cleaning 3 mins read

Keeping your Bosch dishwasher filter clean is essential for optimal performance and preventing drainage issues. Cleaning the filter is a simple process that involves removing, rinsing, and replacing it.

Steps to Clean Your Bosch Dishwasher Filter

Here's a step-by-step guide based on standard procedures for Bosch dishwashers, incorporating the filter removal method referenced:

1. Locate the Filter

The filter system in most Bosch dishwashers is located at the base of the dishwasher tub. It typically consists of two parts: a coarse filter and a microfilter (also known as the fine filter).

2. Remove the Filter System

To remove the filter system for cleaning:

  • Locate the cylindrical filter unit at the bottom of the dishwasher.
  • According to demonstrations, you should rotate the filter unit counter-clockwise until it stops moving.
  • Once unlocked, gently lift the filter unit straight out of the dishwasher base.
  • Note: As observed, the filter might contain some water, potentially from factory testing or recent use.

The filter system might come out as one piece or separate into the coarse filter and the microfilter. If they are together, you may need to twist the parts apart to clean them individually.

3. Clean the Filters

Once the filters are removed:

  • Hold the filter parts under running tap water (lukewarm or warm is best).
  • Use a soft brush (like a clean toothbrush or a vegetable brush) to gently scrub away any food particles, grease, or debris trapped in the mesh or screen. Pay close attention to the fine mesh filter, as small particles can easily clog it.
  • Rinse thoroughly until all visible residue is gone and water flows freely through the mesh.

4. Reassemble and Replace the Filter System

After cleaning, the filters need to be put back correctly:

  • If the coarse and microfilters were separated, fit them back together securely.
  • Place the assembled filter system back into its location at the bottom of the dishwasher tub.
  • Rotate the filter unit clockwise. You should feel it drop into place and lock securely. Ensure it is firmly seated and cannot be easily lifted out again. This is crucial for proper filtration during the wash cycle.
