Rinnai Australia 16 Operation Manual
TROUBLESHOOTING
Your Rinnai Continuous 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 26 Plus
(REU-VRM2630WD), HD250e and HD200e HD200i models only.
In all cases, you may be able to clear the Error Code simply by turning the hot water tap OFF, then ON again. If this does not clear the Error Code,
try pushing the On/Off button OFF, then ON again. If the Error Code still remains, contact Rinnai for advice.
