Is there an error code on my Rinnai tankless?

No code. Tried flushing the unit but that didn’t help. Unit makes a loud rumble (very loud) when it kicks on. This was the only issue for maybe a week or so. Today it started kicking on/off while calling for hot water.

Why does my Rinnai tankless water heater not turn on?

But first, check your plumbing and see if there is a place where the hot water can get back in to the cold water. My Rinnai tankless water heater exhibits this sort of behavior. Cleaning the squirrel cage exhaust fan of bugs, which causes an imbalance slowing airflow, remediates this intermediate hot water flow behavior.

What does the Rinnai error code 63 mean?

Rinnai error code 63 means there is a problem with the water flow and that it may have dropped below 1.3 GPM. Check if the water is running as normal, check all the filters, ensure there is no air bleeding and no air in the system, check the thermal bypass valve if installed.
