How to Clean the Pump Filter on a Whirlpool DU1055XTSS2 Dishwasher

Your Whirlpool DU1055XTSS2 dishwasher fills and drains several times, during the course of each cycle, to remove and replace the collection of dirty water that pools in the bottom of the appliance. As the water drains, it passes through the pump filter, which removes medium to large food scraps before they can enter the plumbing. Cleaning the pump filter every few months reduces the chance of a blockage that could cause problems in your dishwasher.
