I fixed the LC code about 5 months ago by following various videos-- remove water from collection pan. Today the code reappeared, so I repeated the procedure and it did not remove the code. I decided to remove the 4 prong sensor and when I disconnected the wire via the plastic clip, I found water in the connecting clip. I dried the clip and reassembled the sensor and the rest of the machine. Now it functions properly.
