Finish any wash cycle currently in progress, and then release the latch on the Kenmore door to stop the appliance.
Open and lower the door to slide the bottom rack over the door.
Hold the primary trap by the tab. Twist the trap approximately one-fourth to the left to release the part, which can now be removed.
Pull out the corrugated cylinder underneath the trap if your Kenmore model is equipped with a secondary filter.
Clean the parts under warm running water in the sink, using a nylon scrub brush and liquid soap. Rinse thoroughly and then reinstall in reverse order.
