Can anyone tell me if connecting a cold water machine to a hot water supply will cause damage to the machine??? Is it true that the machine wil use less electric to heat the water as it is already hot? My daughter rents a flat where the rent includes heating and there is only a hot water connection for the washing machine so she has connected it up even though the machine is meant to be connected to cold suply....and I am wondering whether the machine is going to break down???
