When it comes to establishing the hot water temperature, keep in mind that 120F°/48C° is a maximum level, not a target. Most dishwashers have internal booster heaters and modern laundry detergents perform effectively at water temperature levels well below that maximum.
You may find you can set your thermostat at a level which produces hot water at or only slightly above the most  comfortable bathing temperature for infants and the elderly. This is usually around 100°F (38°C).
If you’ve lowered the thermostat  to reach an acceptable level, you may also notice a lower utility bill
