Error Codes - Rinnai Energysaver 309FT3 Operation And Installation Manual

Error codes

The Energysaver range has built-in technology to continually monitor performance. If a fault occurs
an error message will flash on the digital display on the control panel. This assists with diagnosing
the fault and may enable you to overcome a problem without a service call.
In all cases you may be able to clear the error by turning the heater off and on again. If the error
code remains or returns when the heater is used again, contact Rinnai.
Faults caused by insufficient gas supply, gas quality, installation or operation errors are not covered
by the Rinnai warranty.
