What does error 07 mean on my Rinnai Zen I24 Boiler?
- KKyle WatersSep 5, 2025
If Error 07 appears on your Rinnai Boiler, it indicates continuous use of domestic hot water for more than 8 hours. Stop using domestic hot water and press the DHW button to reactivate the function. If no one is using hot water, a breakage of the hydraulic pipeline is possible, so call a technician.
