10.1 Processing and Clearing Fault Codes
When a fault occurs, the appropriate fault code will be displayed along with a “Flashing Triangle”
(Figure 10-2).

To process and clear the fault, proceed as follows:
NOTE
If the cause of the fault has not been corrected, the displayed Fault
Code will reappear after performing the following steps.
10.2 Fault Codes and Descriptions
All fault codes are displayed in the E8 Controller display. There are fault codes for three
different devices as follows:
•
E8 Controller: These are divided into four basic categories: PCB Element Faults,
System Manager Faults, Communication Faults, and Internal Faults. These fault codes
are shown in Table 10-1.
•
BCM (Boiler Control Module): Use Table 10-2 to determine the meaning of the
displayed BCM fault code, then look up BCM fault codes in Table 10-3.
•
BMM (Burner Management Module): Use Table 10-2 to determine the meaning of the
displayed BMM fault code, then look up BMM fault codes in Table 10-4.
Processing and Clearing a Fault Code
1. Open the hinged cover on the controller.
2. Press the Program Key. The red LED will light. Also the display will show the fault code and
the number of the suspect module.
3. Correct the cause of the fault.
4. Press the Program Key again. The red LED will go off and the Fault Code will clear.
5. If more than one fault (or more than 1 failed module) exists, repeat the above steps until all
fault codes are cleared.
6. Close the hinged cover on the Controller.
7. Monitor the display to ensure no other Fault Codes appear.
8. Resume normal operation after all faults have been cleared.
