Error code LE1

Has the error LE1 already displayed after three months. Samsung said empty the lint trap. I've long made but there was nothing except water. She no longer went. Technicians needed more than a week. Then came directly to the spare part. Said this is standard because the clamp down on the end is not in place and makes a small hole in the tube. The sensor in the floor stops the machine. Part-exchanged everything ok again!
