What does error code '5C' mean and how do I clean the pump filter?

The '5C' information code means the pump filter is clogged. To clean it, turn off and unplug the washer, drain remaining water using the emergency drain, open the filter cover, turn the pump filter knob to the left, and clean it with a soft brush. It is advisable to clean the pump filter every 2 months to prevent clogging. (Page 50)
