Last year I got one of those high efficiency low water using dish washers.
I hooked it up to hot as per the instructions.
Ran it for a while with the hot water heater off/broken. Seemed to work fine with the dogs precleaning all the plates and bowls.
Then I put the tankless hot water heater on the hot water line. Problem with the tank less is when the dish washer fills the tank less heater doesn't kick on right away.
So all it does is warm the water in the line.

I'm thinking just connect it to cold water.
Now with it wasting hot water it's still not getting hardly any warm water at all. So might as well run it cold.
