"....able to wash with high temp...."

If your idea of "high temp" is above 155-160F, your choice will be limited to 220v machines.

If you want to be able to personally select a particular temperature in a cycle as opposed to selecting whatever the mfgr's euphemism for a cycle may be, you're almost limited to Miele. Almost everybody else offers only "cold"/"warm"/"hot" as selections available but they DO NOT tell you what they mean by those words. For example, my Duet 9400 set on "hot" in a cycle that doesn't utilize the on-board heater actually delivers 100-105F max during the wash. That's not what I call "hot". I do have two cycles available that deliver actual temp of 127F and another that goes to 157F but I had to call and badger the phone-tech in order to be advised what those temps actually were. Be sure you know what your machine will actually deliver.
