[quote=spdrun]What if you connect both hot and cold hoses of the machine to hot water supply, or have a valve that allows you to cross-connect the cold hose to hot water when you need an extra hot wash?

New machines seem to be gimped to a max wash temperature of 120F. What about altering the thermistor that senses water temperature to make it think that the water is 10-20F colder than it is? Should be a simple circuit change.

Or if the circuit is more complex, isolating the sensor from the water flow and just hanging it out in the air would force it to go to full-hot…[/quote]

Yes, I think some people tweak things to make them work. Of course, none of this should be necessary, IMO, as machines should do what the owners want them to do. HE and other “green” technologies should always be one of the options, but it should always be an option. All too often, the “green” technologies end up doing far more harm than good, like when these machines give out after 5 years instead of 20, or when people have to double or triple-wash their clothes (or dishes, in the case of dishwashers…or flush 2, 3, or more times in the case of toilets, etc.) in order to get the same performance as the “non-green” goods and appliances.
