Error Code Description of the Error Malfunction Probable Cause Solution(s)
E 94
Possible low gas pressure
or exhaust recirculation
Boiler does not work, E94
error code flashing on the
screen
> Gas inlet pressure LOW
> Recirculation on fluegas
path
> Blokage on flue or wrong
flue
> Aging or rust on the
electrode
> Electrode position
> Combustion calibration
> Gas valve failiure
> Electronic board
1-) Call for authorised service at first
2-) Check wrong flue OR flue gas blockage
3-) Check recirculation ( flue gas leak ) from flue gas path to fresh air
side, check flue gas sealings specially
4-) Check any problems on the ionisation electrode, (like condensation,
rust etc.), and control poistioning of the electrode, if electrode poistion
wrong calibrate the electrode.
5-) Check combustion CO2 or O2 values on HI and LO mode at sweeper
mode.
6-) Perform Auto Calibration.
7-) if not successfull replace gas valve, and Perform Au-To calibration.
8-) If fault still persists Replace board, but use original service key
from the board dismantled to keep original parameters and calibration
points. If original service key not used aslo adjust P15 releated to the
default value of boiler power and perform Au-To calibration.
Attention: Only authorised service must perform Au-To calibration
E 95
Intermittent combustion
value
Boiler does not work, E95
error code flashing on the
screen
> Harness on electrode and
earth
> Aging or rust on the
electrode
> Electrode position
> Combustion calibration
1-) Call for authorised service at first
2-) Check intermittent contacts on harness carefully
3-) Check any problems on the ionisation electrode, (like condensation,
rust etc.), and control poistioning of the electrode, if electrode poistion
wrong calibrate the electrode.
4-) Check for condensation on the cabling AND/OR on board
5-) Check earth connection between board and electrode
6-) Check electrode cabeling between board and electrode
7-) Check combustion CO2 or O2 values on HI and LO mode at sweeper
mode.
8-) Perform Au-To calibration.
Attention: Only authorised service must perform Au-To calibration
E 96
Flue or air suction way
blockage
Boiler does not work, E96
error code flashing on the
screen > Blokage on flue
> Blokage on air suction
path
1-) Call for authorised service at first
2-) Check wrong flue OR flue gas blockage
3-) Check recirculation ( flue gas leak ) from flue gas path to fresh air
side, check flue gas sealings specially
4-) Check venturi inlet if its blocked
5-) Check any blockage between fan and burner
6-) Check combustion CO2 or O2 values on HI and LO mode at sweeper
mode.
7-) Perform Auto Calibration.
Attention: Only authorised service must perform Au-To calibration
E 98
SW error, board start-up
error fault
Boiler does not work, E98
error code flashing on the
screen
> Boiler software problem
1-) Call for authorised service at first
2-) Replace board direcly, adjust P15 releated to the default value of
boiler power
3-) Perform Au-To calibration.
Attention: Only authorised service must perform Au-To calibration
E 99 Generic fault
Boiler does not work, E99
error code flashing on the
screen
> Boiler electronic
hardware problem
1-) Call for authorised service at first
2-) Replace board direcly, adjust P15 releated to the default value of
boiler power
3-) Perform Au-To calibration.
4-) if not successfull replace gas valve, and perform Au-To calibration.
Attention: Only authorised service must perform Au-To calibration
f l a s h i n g
LCD Half Power mode on Lawa /
Lawa Plus models
Boiler continue to work,
flashing screen boiler still
operational
> Recirculation on fluegas
path
> Blokage on flue or wrong
flue
> Combustion calibration
> Temporary wind
precence
1-) If there is strong wind (ie.wind storm) wait until the wind storm stop
then keep using the boiler as it is 36 or 48 hours boiler try to remove
half power mode by it self automatically by increasing power gradually.
2-) IF problem persist after 48 hours Call for authorised service
3-) Check wrong flue OR flue gas blockage
4-) Check recirculation ( flue gas leak ) from flue gas path to fresh air
side, check flue gas sealings specially
5-) Activate service man menu and dis activate to remove half power
mode
6-) IF problem still persist then perform Auto Calibration
Attention: Only authorised service must perform Au-To calibration
