10.2 Fault Codes and Descriptions
Fault codes are displayed in the E8 Controller display. Use Table 10-1 below to determine the
actual fault code. There are 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 10-2.
• BCM (Boiler Control Module): These fault codes are shown in Table 10-3.
• BMM (Burner Management Module): These fault codes are shown in Table 10-4.
In order to derive the correct error code from that displayed in the E8 Controller display, use
Table 10-1 below to determine the working error code. To use the table, identify the displayed
number from the first column, identify the affected module from the second column, apply the
formula from the third column, and identify the Error Table to reference from the fourth column.

Code
Code to Look Up in Table
Code = 0 N/A No Fault -
Code between 1 and 255 BMM #0 Fault Look up code 10-4
Code between 256 and 511 BMM #1 Fault Subtract 256 from reading 10-4
Code between 512 and 767 BMM #2 Fault Subtract 512 from reading 10-4
Code between 768 and 1023 BMM #3 Fault Subtract 768 from reading 10-4
Code between 1024 and 1279 BMM #4 Fault Subtract 1024 from reading 10-4
Code between 1280 and 1535 BMM #5 Fault Subtract 1280 from reading 10-4
Code between 1536 and 1791 BMM #6 Fault Subtract 1536 from reading 10-4
Code between 1792 and 2047 BMM #7 Fault Subtract 1792 from reading 10-4
Code between 2048 and 65279 N/A Invalid Codes -
Code above 65280 BCM Fault Subtract 65280 from reading 10-3
Example:
Based on the above, a code reading of “261” means the fault occurred on
BMM #1. The fault code is (261 – 256 = ) 5. An Error Code of 5 from the
BMM Fault Codes table means “Flame Loss During Run”.
