Product review (5 stars): Saved money buying the part on Amazon and installing it myself
Fixed the problem in my Maytag MDB7759AWS dishwasher.  Installed easily and no additional parts needed.  Did need to uninstall the dishwasher and remove from underneath the countertop, as you need to access the back to remove the nut holding the heating element in place.  Lots of videos on YouTube showing you how to install it.
