Error Code Description of the Error Malfunction Probable Cause Solution(s)
E 08
electrode
Water blockage on syphon
E 09
system
the screen
Lack of water on the
system
Pump blockage
Pump harness
open all valves
measure voltage from connectors
9-) Check heat exchanger water path
E 10
temperature RETURN
sensor faulty
the screen
temperature sensor faulty
E 11 Gas valve modulator
the screen
Gas valve harness
E 12 DHW temperature Probe,
the screen storage tank faulty
E 13
Exhaust temperature
probe over-temperature
alarm Boiler does not work, E13
error code flashing on the
screen
> Over temperature flue
gas outlet value > 105 °C
1-) Call for authorised service at first
2-) Check Pump operation if the pump circuation through the heat
exchanger is enough
3-) Check intermittent contacts on harness carefully specially Pump
and PWM cable
4-) Check if there is air on the heat exchanger, remove air
5-) Check heat exchanger water path againts clogging
6-) Installation water path againts clogging
7-) Reset & Restart boiler
E 14
Exhaust ( FLUE )
temperature probe fault
Boiler does not work, E14
error code flashing on the
screen
> Central heating FLUE
temperature sensor faulty
1-) Call for authorised service at first
2-) Check intermittent contacts or open contacts on harness carefully
3-) Check FLUE temperature sensor ressistance if its out of tolerance
replace NTC
3-) Check cabeling and connectors between FLUE NTC and board
4-) Reset & Restart boiler
E 15
Fan failure (feedback/
supply)
Boiler does not work, E15
error code flashing on the
screen
> Fan harness
1-) Call for authorised service at first
2-) Check intermittent contacts or open contacts on harness carefully
on fan main supply, if main supply not connected then fan will not
operate and boiler will not ignite
3-) Check intermittent contacts or open contacts on harness carefully
on fan PWM connection, if PWM connection not connected then fan
will work at %100 capacity
4-) Reset & Restart boiler
E 16
Central heating
temperature RETURN
sensor faulty Boiler does not work, E10
error code flashing on the
screen
> Central heating RETURN
temperature sensor faulty
1-) Call for authorised service at first
2-) Check intermittent contacts or open contacts on harness carefully
3-) Check RETURN Central heating temperature sensor ressistance if
its out of tolerance replace NTC
4-) Check cabeling and connectors between RETURN NTC and board
5-) Reset & Restart boiler
E 17
between FLOW and LIMIT
NTC (Double Heating
Probe) faulty FLOW and LIMIT sensor (
DOUBLE NTC) malfunction > FLOW and LIMIT Sensor
( double NTC ) faulty
1-) Call for authorised service at first
2-) Check CH temperature probe ressistance (double CH NTC probe
is used as high temperature limit device) if its out of tolerance replace
double NTC
3-) Check cabeling and connectors between double NTC and board
4-) Reset & Restart boiler
