> recommends connecting to the cold water inlet unless the hot water is known to be heated by a very efficient source

Huh? How does it matter to the dishwasher?

It doesn’t. They just assume that the user is looking for the most efficient solution. There are pros and cons though. The delicate crystal cycle uses a very low temperature and will only work with cold water. Some of the faster cycles will only be as fast as claimed if the supplier water is already hot.
