[Washing Machine] Should hot water be supplied when using the sanitize wash?

.Unlike normal fully-automatic washer, the sanitizing washer has a sanitize wash function.

.Using only a cold water supply, the sanitize wash is possible with the help of the internal heater.

 However this method consumes a lot of energy and may lead to a higher electricity fee depending

 on the temperature of water supplied.

.Therefore it is advisable to use sanitize wash when hot water is connected to the machine.
