What does 10 mean?
The Rinnai 10 error code indicates that your water heater has sensed a restriction in the airflow to its combustion chamber or exhaust vent. This could be due to a blockage caused by lint, dust, or other debris. If left unchecked, this could lead to a buildup of carbon monoxide, a hazardous gas that can be deadly in high concentrations. It's important to address this issue promptly to ensure the safety of your home and family.
