Washer did not dry dishes or get really hot and run time was very long and was starting to have a scum build up in the washer. I initially changed the heating unit and that did not fix it and then I saw a review with my same issue that was successful so I replaced the control unit and it has solved my problem.
This part is very easy to replace, I did not even have to pull the washer out of the cabinet.
I removed the outside of the door right in place. Took about 15 min. If you are not someone with a lot of tools you will need a star screw driver that you can pick up a set at harbor freight cheap.
Hope this helps get out there and DIY. I did this because every time I try to hire a "professional" it seem they don't know anymore about what they are doing that I do. I can replace parts as well as anyone !
