What to do if Rinnai Water Heater starts then shuts down immediately?
- JJoseph AndradeAug 20, 2025
If your Rinnai Water Heater starts and then immediately shuts down, verify that the power is still on. Also, check that the gas valve at the unit and the gas meter are fully open. Ensure that your hot water tap is fully open as well.
