Product review (5 stars): Easy to replace for most who are familiar with socket ...
This sub $20 part fixed my LG washer and saved me hundreds in a home repair visit from a professional.  Easy to replace for most who are familiar with socket wrenches and screw drivers.  Well worth trying if you get the common and dreaded LE error.  There is even a wonderful video online in how to disassemble your washer to fix this.
