Extraklasse 1300 Siemens Washing Machine?

If the machine is hot and cold fill but only the cold water valve is operated it is because household hot water is 65`C so if you set a program that is less than 65`C it will only fill with cold water and heat it up inside the machine. If you set 90`c prog with no prewash it should fill via the hot valve. (because we generally wash at 40`C these days new machines only have a cold fill valve anyway) Cheers
