Table 10-1: E8 Controller Fault Codes
FAULT CODE FAULT DESCRIPTION
PCB Element Fault
E 1 High limit thermostat
E 2 Supplier low gas pressure
E 4 Flame absence during ignition time
E 5 Flame absence during operation time
E 6 High temperature on element (> 203°F)
E 8 Low water pressure (only with SensorLogic)
E 10 Local PCB failure
E 11 Flame presence before ignition cycle
E 12 Local flow sensor failure
E 13 Auxiliary sensor failure (DHW)
E 14 Global return sensor failure
E 15 Difference between global return sensor and local flow sensor > 86°F (rp +10)
