Rheem Tankless Water Heater Error Code 61: Meaning and Fix
Applies to: Rheem Eagle series tankless water heaters, indoor and outdoor (Use and Care manual AP22009, Service Error Code Chart); other Rheem tankless lines such as RTGH may use different codes.
Reading the tankless water heater display
A tankless water heater shows its fault as a number or letter code on the unit display or on the wired remote controller, and some models keep a short history of past codes. Write the code down exactly as shown before you reset the unit, and check the rating plate for the model number, because the same number can mean different things between series.
This page lists the fault codes this brand documents, with likely causes and a short repair path. Check the model label on your unit before using any chart.
