CHAPTER 6: TROUBLESHOOTING
6.1 E8 Controller Fault Codes
Fault codes are displayed in the upper right hand section of the E8 Controller display (see
Figure 6-1). Use Table 6-1 (next page) to determine the fault message. There are codes for the
following three different devices:
• 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 6-2.
• BCM (Boiler Control Module): These fault codes are shown in Table 6-3.
• BMM (Burner Management Module): These fault codes are shown in Table 6-4.

6.1.1 Using the Fault Code Tables
When interpreting fault codes in the E8 display that refer to the E8 controller itself, the fault
number is directly referenced to an fault description in Table 6-2.
Displayed fault codes not listed in Table 6-2 refer to devices other than the E8 controller, such as
the Boiler Management module (BMM) or Burner Controller Module (BCM). Use Table 6-1 (and
the formula described below the table) to arrive at a fault number, which can be looked up in
Tables 6-3 and 6-4 for the fault description.
In order to derive the fault message from the code displayed in the E8 Controller display, use
Table 6-1 below to determine the working fault code. To use the table, find the displayed
number in the first column, identify the affected module from the second column, apply the
formula from the third column, and identify the fault table to reference from the fourth column.
