Your Rinnai continous flow water heaters has a self diagnostic capability. If a fault occurs, an Error
Code will flash on the digital monitor or status monitor* if you have water controllers. This assists with
diagnosing the fault, and may enable you to overcome a problem without a service call. Please quote
the code displayed when enquiring about service. *Status Monitor available on Infinity XR26 Plus and
