“How hot can I get the water temperature using the built in heater and how long does it stay at that temperature? How hot can I get the water temperature using the built in heater and how long will it maintain this water temperature. I am used to the European models where you can actually dial in the wash water temperature all the way up to boiling. Does this water have this option and how long does the water temperature stay at this temperature? I find that whites in either most American top loaders and front loaders just don't stay white they get quite dingy. I have tried bleach and different detergents but finally determined that it is the wash water temperature that has the greatest impact.”
