Wow, my husband and I just got done with the process. It saved us $1500, I was ready to pay out for a new set, but this really does work. Our machine kept getting the error, we took the front piece off and unscrewed the trap and cleaned it out and it is running great. But the one thing that I will say, when the previous person said have many, many towels, be ready to have every one that you have, because we practically flooded out entire laundry room. It is a nasty cleaning but it will save you a bundle. Thanks so much for this wonderful advice, it is so greatly appreciated.
