Fault Codes
If there is a malfunction the appliance may shut
down as a safety precaution and display a fault
code to assist in diagnosing the problem. The
fault code will flash in the display on the control
panel. When making a service call, this code will
assist with diagnosing the fault.
You may be able to clear the fault code by turning
the heater off and then on again. If the fault code
remains or returns on the next operation, contact
Rinnai or your nearest service agent and arrange
for a service call.

Service Call.
[1] Remove any obstructions. The flue needs to be kept clear to expel exhaust gases. If the appliance
fails to operate contact a qualified service agency.
[2] If the fusible link needs replacement, it must be done by a qualified service agency. In addition, the
cause of the overheat needs to be determined. The fusible link is a one use safety device that breaks
to shut off the appliance.
