It has a "temperer" that's supposed to limit the hot water to something just above where the water heater's thermostat is set - but it's mechanical, and not all that quick to respond.

Except for some reason the laundry sink is plumbed in directly to the untempered hot water, so you can dispense near-boiling water there. Not sure why you'd want to, and it far exceeds the washing machine's specifications.
