The vast majority of washing machines do both hot and cold, at least in North America. Hot is the default. The machine doesn’t make the water hot though, it just takes hot water from your hot water tank. This means that there are two machines that are running at the same time. You have a hot water tank that is going to be boiling more water and the washing machine that is using the hot water that is being boiled. To use cold water, you typically have to select the cold wash setting on most washers here in North America. In this case, it just takes water from the tap instead of the hot water tank.
Some washing machines do also have the ability to heat water above 60°C for sterilisation purposes, as most domestic hot water heaters only do 40-50°C.
