wrongly programmed
BCU or PB
electrical circuit is
short circuited, or
APS is jammed
no air transport to the
burner; flue or air
inlet is blocked, or
APS is jammed, or
air signal hose not
connected to the air
intake pipe or water
in hose
burner door clixon
tripped because of
overheating of the
burner door or the
water flow is
restricted, or back
wall thermal fuse has
tripped because rear
wall insulation disc
(combustion
chamber) is
damaged or broken.
Solving
reset BCU or replace BCU
and or display unit
check gas supply and ad-
just gas valve, reset BCU
reset BCU replace gas
valve or wiring harness
reset BCU or replace BCU
reset and check blocking
code
check wiring or replace Fan
if not solved check fuse on
BCU or replace BCU
check wiring or replace Fan
if not solved check fuse on
BCU or replace BCU
check wiring or replace Fan
if not solved check fuse on
BCU or replace BCU
reset BCU or replace BCU

check wiring or replace
APS
check if there are any
obstructions in the flue or
air intake, replace APS if
jammed, connect air hose
to the air intake pipe,
remove any water from the
hose.
check burner door gasket
and replace burner door
gasket and reset clixon on
burner door or check
circulator and waterflow
and replace circulator or
increase water flow check
also if valves are closed or
check if rear wall fuse is
broken if so replace and
also replace rear wall
insulation disc (combustion
chamber).
