There are plenty of buttons on the washer (which is a user-interface nightmare of its own). Two help a little: 'Heavy Duty' and 'Extra Rinse'. Selecting both leaves the clothes smelling slightly less of sweat and dirt. And of course when the cycle completes, it turns off to save (miniscule) power. Turning it on results in the default settings again!
Googling it, I see no hack to defeat the settings. Just a lot of talk about strange error codes and how to reset them. Sigh.
Mine (front loaded) has a pre-wash (2 hour program) or "soaking" mode for extra dirty clothes (4h), and I can select temperatures from 0-90 degrees celsius, but most clothes get clean at 40 degrees.
I had to do an obscure button trick described in the user manual to have it remember the previous settings after a completed cycle, though.
Maybe I can find a trick in the manual; thanks for that idea.
Doesn't you dishwasher have any adjustment to set the temperature or length of the cycle? What model do you have?
My appliances are all "A" rated (EU energy label), but to get that rating for the dishwasher I have to use the "eco program", and I'd think there was something similar in the US?
