Section 9. Troubleshooting
9.1
General Heater Troubleshooting
Table 11 lists some of the more common prob-
lems, causes and solutions encountered when running
the heater. Most problems occur when the heater is
being started for the first time after installation or at
spring start-up. Careful installation and maintenance
will help ensure years of trouble free use from your
LXi heater.
Be aware that premix combustion systems of the
type found in the LXi heaters have special character-
istics that affect operation and troubleshooting. See
Section 10.2
and
Section 10.3
for important informa-
tion about the system.
9.2
Service Codes
The LXi controller monitors several functions
of the heater. In the event of a malfunction, the LXi
controller will display a FAULT message. Table 12
lists the LXi Heater Service Codes along with potential
causes and remedies.

Ignition Control LED Service Codes
In addition to the service codes shown in the
previous section, the ignition controller in the LXi
heater has an LED light that flashes to indicate various
different faults. Table 10 lists the LED codes and the
