  Fault 

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.

the overheat needs to be determined.  The fusible link is a one use safety device that breaks to shut off the 
appliance.

operate contact a qualified service agency.
