When connecting the machine to the taps, do you need to connect the machine to hot from the geyser or the washing machine makes the water to be hot

Hi from retired Englishman in SW France,
I think you will find that all washers are able to heat water. If they are hot and cold fill, they use the heater if the hot water supplied is not hot enough for the particular wash. If they are cold fill only then they need the heater for all non-cold washes.
If you purchase the washer you are thinking of and it is cold fill only, it will have only one inlet hose, the cold water one and it is a straight forward installation- hose from washer screw into cold supply tap.
If it is hot and cold fill you have a choice- either go to the expense of plumbing hot water to it OR purchase a 'Y' 'tap' adapter. The adapter screws onto the cold supply (by the 'bottom' of the Y) and the hot and cold hoses which go to the washer are screwed into the (top) 2 ends of the 'Y'. The washer opens its hot valve, gets the only water supply which is cold through what it thinks is the hot hose and heats it up accordingly. When it wants cold it opens its cold valve and gets the cold water through what it thinks is its cold hose- which it is!
I hope this clarifies the situation for you and if it has please consider a 4 thumbs up for the rating.
Thanks and good luck!
