In UK go to B & Q and buy a " Y " connector, what it does is convert your existing cold only outlet to 2 cold outlets, so that you can now connect both H & C hoses, the machine does't know, and will heat the water anyway FOOTNOTE It has been discovered that it is more efficient to do it this way, rather than connect to hot water as well. By the time the hot water got to the machine it was cold anyway !!! And as a further footnote, manufacturers are making cold fill ONLY machines Plumbers have known this phenomen for donkey's years. FOOTNOTE In UK all machines have a water heater. pc beach may be in USA where there are different requirements.
