A couple of years ago we had the LG front load washer and dryer and one of the sensors in the washer went out. This was after the mfg. warranty had expired. I had additional coverage on both and it still cost a pretty penny to repair. As far as the smell goes all most all HE washers gets it. I recommend that you use the washer cleaner tablets that can be bought at almost any supermarket. It is recommended that all machines that uses HE detergent use the cleaner tablets once a month to counteract the smell. I do this for my HE washer and all is well. There are different kinds of cleaners but I recommend the tablets. I'm not sure if it's ok to give the brand name that I use but it comes in a green plastic pouch with black lettering across the front. Try it, it works.
