Malfunction
description
Cause of malfunction
Recommended troubleshooting
methods
01
Overheating
(upper temperature
limit exceeded)
Temperature near one of the
sensors exceeds 120ºС
1. Check the entire liquid circuit for air
blocks.
2. Check the pump.
3. Check the overheating sensor and the
temperature sensor.
4. Check the antifreeze for suitability at
current ambient temperatures
03
Temperature
sensor 1 fault
Short or open circuit in the
electric wiring
Replace the sensor assembly
04
Temperature
sensor 2 fault
05
Flame detector
fault
Short circuit to frame or open
circuit in the detector wiring
Check the flame detector
06
Control unit
temperature sensor
fault
The temperature sensor is faulty
(located in the control unit,
cannot be replaced)
Replace the control unit
09
Glow plug fault
Short or open circuit, control
unit fault
Check the glow plug.
Check the control unit
10
Air blower fault.
Speed lower than
rated
Foreign particles obstructing
spinner movement, or the
spinner hits the air blower cover
Check the electric wiring.
Check the air blower for dirt
12
Shutdown due to
overvoltage
Power supply voltage
is above 16 V
Check voltage at ХS2 connector on the
heater. Check fuses, the battery, the
vehicle voltage regulator, and power
supply wiring
13
All attempts to
start failed
Failure to ignite
(after two attempts)
Check the fuel line, the fuel pump, and
the air blower. Check the exhaust pipe.
Check the combustion chamber, clean
the opening in the plug nozzle of the
combustion chamber if necessary
14
Pump fault
Short or open circuit of current-
conducting parts
Check for short or open circuit of the
pump wiring; check the pump.
Clean the pumping elements of the pump
15
Shutdown due to
undervoltage
Power supply voltage
is below 10 V
Check voltage at ХS2 connector on the
heater. Check fuses, the battery, the
vehicle voltage regulator, and power
supply wiring
16
Ventilation time
exceeded
The flame detector is not cooled
down by purging sufficiently
Check the air intake and the gas exhaust
pipe. Check the flame detector; replace if
necessary
17
Fuel pump fault
(short circuit)
Short circuit in the fuel pump
wiring
Check the fuel pump
20
No communication
between the
control unit and
the control panel
Short or open circuit in the
electric wiring between the
liquid heater and the control
panel
Check the 5 A fuse.
Check circuits and terminals
