Understanding Error Code 12
I encountered Error Code 12 on my Rinnai tankless water heater, and let me tell you, it can be quite frustrating. Error Code 12 typically indicates a flame failure. This means that the unit did not detect a flame when it tried to ignite, leading to the error code.
One of the common reasons for Error Code 12 is an issue with the gas supply. It could be due to low gas pressure, a blockage in the gas line, or even an empty propane tank if you use propane for your water heater.
Another possible cause for this error is an obstruction in the unit’s combustion fan or exhaust vent. If these components are blocked or not functioning correctly, it can prevent the heater from lighting up successfully.
It’s essential to address Error Code 12 promptly to ensure that your Rinnai tankless water heater operates efficiently. Checking the gas supply, inspecting the combustion fan and exhaust vent, and ensuring proper ventilation are good initial steps to troubleshoot this error.
