Yes, it depends on one's individual installation. All the houses I lived in had recirc pumps and a big water storage tank so hot water was always plentiful. My washer is in the basement, which is excluded from the circulation circuit. Still, it only takes two to five liters for the hot water to come through - if I don't purge the line. The dishwasher is on cold water as it needs (or prefers) cold water for the condensation drying cycle. But even with cold water coming in, the dishwasher takes it to steaming hot within ten minutes.
