Product review (4 stars): Works on My Older KitchenAid Superba
Worked for my Kitchenaid Superba dishwasher (stainless tub) which was new around 2002?

Only 4 stars, because It did change some of the control panel functions (fewer available now), but it is heating the water and drying.

And most importantly, I didn't go through all the time and effort only to have it not work.  It took me a couple hours - well worth it to me.  Watched a couple YouTube videos to get an idea of what to do.  If you're on the mechanical side, and have a couple basic tools, my guess is it should go just fine for you.

Need the star shaped screw driver bits in order to access and change the control panel, but beyond that the most basic tools should be enough.

I did not need to order any additional nuts, bolts, etc.  - I just used what was on the old dishwasher and what came in the heater / control board kit.

For safety, remember to turn off power and water before working on it.
