With these suggestions, we must remember that most European washing machines are made completely different to the ones generally found and used in North America. When we moved to Canada my mom insisted on getting a machine with a heater as we were used to, but those were still very new and took much longer than even our machines here. In Europe most machines have only the cold water connection, and then the water is heated to the temperature set, Therefore cold = 30 deg C / 86 deg F. Warm = 60 deg C / 140 deg F and hot or in our case boiling= 95 deg C / 203 deg F.
In all the machine at my family and friends' houses in Canada or the states, they have cold = whatever the temperature comes out of the cold water tap, Warm= both the cold and hot water tap fully open, and hot= whatever temp comes out of the hot water tap, and that depends on what the boiler is set to and when it was heated up the last time, probably about 130 to 150 deg F...
Whenever I forget to explain the machine and the temperature difference to visitors from overseas, we end up with lots of shrunk, and often some ruined clothing...
But, the warmer temperatures also mean we can get away with a lot less chemicals (never use bleach & rarely need stain removers), the whites generally remain white, and towels, cleaning rags, bathroom carpets and tea towels, etc get clean and 'sterilized' because they are truly 'cooked' till all the bacteria are dead.
Just saying: as we are such an international forum, make sure you are comparing apples with apples, and not apples with pears... They might look similar, but are completely different fruit
