TROUBLESHOOTING
07
During usage, the heater may be unable to start normally,
or may flame-out soon after startup, leading to a locked
malfunction state. In such cases, try to restart the heater:
turn it off, keep it shut down for at least 3 seconds, then
start it again.
Circuit malfunction can occur for various reasons, such
as: corrosion (of connectors, wires, fuse, battery poles),
poor connector contact, incorrectly connected wires, etc.
Users must pay attention to inspection and maintenance
to prevent such problems.

2.1 appearance of this code immediately after start-up represents a mainboard fault; the mainboard
will need to be replaced;
2.2 appearance of this code after start-up and about 15 seconds of fan operation represents a glow plug
fault; the glow plug will need to be replaced;
2.3 appearance of this code about 50 seconds after start-up represents an installation problem; please
check the power supply voltage.
