Rinnai Australia 24 Operation Manual
TROUBLESHOOTING
ERROR CODES
Your Rinnai Continuous Flow water heaters has a self diagnostic capability. If a fault occurs, an Error
Code will flash on the digital monitor of your 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.
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.
No power display
When power to the water heater is disconnected the LCD of all wireless water
controllers will display as shown. Check that power is available, the water heater is
plugged in and that the power point is turned ‘on’.
Troubleshooting Without Water Controllers
If you have no water controllers and experience the following symptoms, carry out these suggestions.
If the symptom continues, contact Rinnai for advice.
SERVICE
Wired and wireless water controllers, transceivers and water heaters do not contain user serviceable
parts and must only be serviced and repaired by an authorised person.
