Rinnai Direct Vent Service Manual 7
Fault Isolation
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.
Fault codes should be used to assist in identifying the
cause of the failure.
After the problem has been corrected, the fault code
will clear only after the appliance has been turned off
and back on. The code will be stored into the memory.
Some faults may cause a hard lockout where the
appliance shuts off and corrective action is required
before the appliance will operate.
Accessing Fault Codes
Up to 10 fault codes are stored in the PC Board and can be recalled by simultaneously pressing the “Economy”
button and both temperature control buttons for 2.5 seconds while the appliance is turned OFF. After the buttons
are released, the fault codes will be displayed in 2 second intervals beginning with the most recent fault code.
Models with analog controls and models with digital LED’s each have their own set of fault codes.
On models RHFE-431WTA, RHFE-556WTA, RHFE-556FTRA:
Under SET the codes in memory are numbered 1 through 10 with “1” as the
most recent. Under ROOM the fault code will be displayed.
Models with analog controls:
The fault code will display by lighting up 1 to 4 of the temperatures at
the same time. For example, if the temperatures 60, 64, and 68 are lit
up then the fault code is 60*64*68 - Abnormal Combustion Fan RPM.
On models all other models with digital controls:
The codes in memory are numbered 1 through 10 with “1” as the most
recent. The temperature display will show “1” and then show the most
recent fault code. A “2” will then be displayed followed by the second
most recent fault code. The 10 most recent fault codes will be displayed
in this manner.
