Due to the age of the machine, I ordered the complete assembly with both valves and housing and replaced it. The video provided by on your website was very helpful. It went pretty well with one exception, both posts on the AP6017590 Bezel for the retaining screws snapped off when reinstalling them. I didn't even get them tightened all the way, the plastic had become weak from age and broke off. Do yourself a favor and order this piece too, it would have been worth it to me. However, I needed to get the machine back together ASAP so I "backyard engineered" it back together by drilling through the bezel using what was left of the post as a guide, installing longer thread cutting screws from the front and using the broken off posts on the backside of the assembly like nuts. Other than that little hiccup it went easier than anticipated and would have taken a lot less time.
