So, after a lot of digging for my dishwasher I found the heating element and how to change it on this site. I started there. When we reran the dishwasher the same thing was happening... The steam sanitize light was blinking and not completing... Then I found a post about the high limit thermostat. Granted I couldn't find anything on my Maytag dishwasher, only Whirlpool, turns out they are the same, or so my research was telling me. After I ordered this part, we used the video tutorial to try to replace it. Well. we ended up taking the whole dishwasher out and putting it on its side so we could easily see the bottom. The part was not where the tutorial showed - not surprising. So I started calling out the color of the wires I saw on the video so my hubby could find the part. Eventually, we found it was not the part with the blue and red wires connected, we didn't have those color wires, hubby found a blue/red wire and that's when we found the part and followed the video for replacement.
After the part was replaced I read something about needing to reset the machine so it would start using that broken part again. Now, I didn't know this when we replaced the heating element, so that might have fixed it, but we never did the reset. After combing sites to find out how to do a reset on my model, we found that we needed to choose any 3 keys on the touchpad and press them in 1-2-3, 1-2-3, 1-2-3 sequence. This started a quick cycle through by the dishwasher software, about 25 minutes, and we loaded the dishwasher up and retested the steam sanitize and LOW AND BEHOLD IT WORKED!!!! Yeah!!! We fixed it. Hope this helps someone else.
