16 - USE
Loc 18 Internal software error Replace the power control board
Loc 19 Internal software error Replace the power control board
Loc 20 Flame lost three times Control: that the ionisation current is at a value over 60 (see
parameter 1008)
Control: that the fumes exhaust must be protected with a
wind-proof grid
If the ionisation current is not over 60, the CO2 must be checked (see
chapter 15.8) and restore the correct value. Check the ionisation electrode
and replace it if necessary. Check the integrity of the ionisation current
electric circuit cables.
If the fumes exhaust is placed in a vertical wall it must be protected
with a wind-proof grid. If the fumes exhaust is positioned on the roof,
make sure that it is not in an area of reflux and that any windproof
chimney pot is really efficient.
Loc 21 Internal software error Replace the power control board
Loc 22 Internal software error Replace the power control board
Loc 23 Internal software error Replace the power control board
Loc 24 Internal software error Replace the power control board
Loc 25 Gas valve circuit
(when this error happens to
burner 1 (Master), stops other
burner)
a - Check High limit temperature switch
b - Check High limit flue temperature fuse
WARNING!!!
If the high limit
temperature fuse melt, before any replacement, it is
mandatory to contact the appliance manufacturer
to prevent any permanent damages to the heat
exchanger. Failure to comply with this requirement
can result in excessive levels of carbon monoxide
which can result in severe personal injury or death!
Loc 26 Internal software error Replace the power control board
Loc 27 Flame present with closed gas
valve
Replace the gas valve
Loc 28 Flame present with closed gas
valve
Replace the gas valve
Loc 29 Interlock input
(when this error happens to
burner 1 (Master), stops other
burner)
a - Check LWCO connection
b - Check flue blocked pressure switch
a - If LWCO intervenes, try to reset it
b - Check if flue gas line is free from any blockage
Loc 30 Internal software error Replace the power control board
Loc 31 Five times flame lost during one
demand
a) Check detection electrode;
b) Check for any obstruction on air inlet / flue exhaust sytem
c) Check for any air inlet contamination from combustion gas
(Ex. flue exhaust terminal too much near air inlet terminal)
a) Try to replace detection electrode
b) Remove any obstruction
c) Remove the cause of the air inlet contamination
Loc 32 Internal software error Replace the power control board
Loc 33 Internal software error Replace the power control board
Loc 34 Internal software error Replace the power control board
Loc 35 Internal software error Replace the power control board
Loc 36 Internal software error Replace the power control board
Loc 37 Internal software error Replace the power control board
Loc 38 Flue gas sensor does not
increase
a - Check flue gas sensor match section 17.10
b - Check if flue gas sensor (parameter 1006) increases its
temperature when burner is on
a - If does not match it, it must be replaced
b - If temperature does not increase, replace the flue gas sensor or the
control board
