What does the error code '4C' mean and how do I fix it?

The '4C' information code indicates that the mesh filter of the water hose is clogged. To fix it, turn off the washer, unplug the power cord, close the water tap, disconnect the water hose, and pull out the mesh filter using pliers. Submerge it in water, dry it completely in the shade, then reinsert it and reconnect the hose. (Page 49)
