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.

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”.
