The temperature setting and the flow meter alarm setting may both need to be reset after a power outage.
Why doesn't the flow meter alarm sound even when filled to the set amount in Noritz NRC1111-DV Water Heater?
If mixing valves are used, or if cold water is mixed with hot water at the fixture, the tub will fill more than the setting of the flow meter alarm.
