How do you replace a Bosch dishwasher filter?

To replace a Bosch dishwasher filter, remove the lower rack, twist the filter assembly counterclockwise, lift it out, clean or replace it, and reinstall by locking it clockwise until secure. Most Bosch filters are reusable and only need regular cleaning, not full replacement.

Bosch Dishwasher Filter Replacement — Step-by-Step Guide

Step 1: Remove the bottom rack

Slide out the lower rack to access the filter at the base of the dishwasher tub.

Step 2: Unlock the filter system

Turn the cylindrical filter handle counterclockwise (usually a quarter turn).

Step 3: Lift out the filter

Gently pull the filter assembly upward. It typically comes out in one or two parts:

• Coarse filter (large debris)
• Fine filter (food particles)
• Microfilter (grease and fine sediment)

Step 4: Clean or replace

• Rinse under warm running water
• Use a soft brush for grease buildup
• Replace if cracked, warped, or permanently clogged

Step 5: Reinstall correctly

• Place filter back into position
• Turn clockwise until it locks firmly
• Ensure it sits flush (incorrect seating causes drainage issues)
