rE 28
Maximum locking number reached
Usable RESET number reached.
Warning: Failure can be reset successively for
maximum 5 times, then function is terminated for
at least one hour and one try is possible per hour
provided that having maximum 5 tries combi is
reset.
E 37 Low voltage failure
Seen when the voltage required for operation
of combi is under envisaged limits.
Combi starts again without requiring RESET after
the Electrical voltage turns into normal conditions.
E 40 Electricity network frequency error Fluctuation in electricity frequency
Call the authorized service in case of repeated
after reset. (1)
rE 41 Flame loss after 6 successive ignitions.
Control whether gas supply line valves are
open. Respectively, control whether gas valves
of your combi, home and building are open .
