How to Clean a Bosch Dishwasher Filter

Updated March 23, 2017

Dishwashers are a timesaver when it comes to cleaning your dishes. With some quick preventive maintenance, they can provide trouble-free operation for many years. Bosch dishwashers include a filtering system that keeps large food particles away from the main pump and drain pump. Although these filters are mostly self-cleaning, they should still be inspected regularly and cleaned when necessary.

Open the dishwasher door completely and remove the bottom rack from the dishwasher.

Grasp the cylinder filter and unscrew counterclockwise one-fourth of a turn. You can find the cylinder filter on the bottom of the dishwasher directly in front of the bottom spray arm.

Lift out the cylinder filter to remove. Check for the presence of large debris. Turn upside down and tap gently to remove any large particulates from the filter.

Clean the cylinder filter under running water to remove any residue.

Remove the flat filter by lifting it from the dishwasher floor. Rinse under clean water to remove any residue.

Reassemble the filter in reverse order of disassembly. Return the flat filter to the dishwasher floor. Reinsert the cylinder filter into position and lock the entire filter system in place by turning clockwise one-fourth of a turn. Make sure the arrow marks on the filter system are opposite from one another after locking the system.
