Blocking errors
“Err”
Blocking errors are generated by a
permanent fault. Ther’is no way to
unlock the unit other than to resolve
the cause of the fault.
On units model 399 up to 1000,
because are multiburners, when
a burner go into a blocking error
state, you’ll see
icon and the
corresponding burner icon (

or ) in fail that blink. To know the
blocking error code you have to press
the RESET button and display will
show you the blocking error code.
Press and hold for 5 seconds RESET
key in order to back in normal display
condition.

Err 52 Internal hardware error Replace the power control board
Err 53 Internal hardware error Replace the power control board
Err 54 Flame is detected in a state in
which no fl ame is allowed to
be seen.
Replace the power control board
Err 55 Low water pressure error Check pressure sensor Replace the pressure sensor
Err 56 Low water pressure error Check pressure sensor Replace the pressure sensor
Err 57 Low water pressure error Check pressure sensor Replace the pressure sensor
Err 58 Low water pressure error Check pressure sensor Replace the pressure sensor
Err 59 Low water pressure error a - Check the pressure into the water system and eventually
increase it
a - If water system pressure is over parameter 3022, replace the water
pressure sensor
Err 60 High fl ue gas temperature error a - Check the combustion effi ciency of the burner in fail.
Combustion Effi ciency must be higher than 92%.
b - Check the fl ue gas temperature sensor match section
15.10
a - If combustion effi ciency is lower than 92%, try to clean the fl ue gas
side and the water side of the heat exchanger;
b - If fl ue temperature sensor do not match section 15.10, it must be
replaced.
Err 61 Return temperature is higher
than stay burning temperature
Check if temperature sensor match section 15.10 If temperature sensor do not match section 15.10, it must be replaced.
Err 62 Block drain switch is active a - Check if the condensate drain is blocked
b - Check if the condensate box is blocked
a - Remove any obstruction from the condensate drain
b - check the condensate box, if medium is exhaust it must be replaced
Err 64 No correct Frequency signal or
no communication with the WD
Check the frequency signal. It must be between 55 and
65Hz
If out from range, ask your electrical supplier. Diversely try to replace the
power contro board
Err 65 Hot neutral reversed Check supply voltage polarity Reverse supply voltage polarity, if it’s the case
Err 66 Net freq. error detected in the
main
Check the frequency signal. It must be between 55 and
65Hz
If out from range, ask your electrical supplier. Diversely try to replace the
power contro board
Err 67 Faulty earth connection Check the earth connection to the appliance Repristinate the earth connection
Err 68 Watchdog communication error Replace the power control board
Err 72 Supply sensor open Check if temperature sensor match section 15.10 If temperature sensor do not match section 15.10, it must be replaced.
Err 73 Return sensor open Check if temperature sensor match section 15.10 If temperature sensor do not match section 15.10, it must be replaced.
Err 76 DHW sensor open Check if temperature sensor match section 15.10 If temperature sensor do not match section 15.10, it must be replaced.
Err 80 Supply sensor shorted Check if temperature sensor match section 15.10 If temperature sensor do not match section 15.10, it must be replaced.
Err 81 Return sensor shorted Check if temperature sensor match section 15.10 If temperature sensor do not match section 15.10, it must be replaced.
Err 84 DHW sensor shorted Check if temperature sensor match section 15.10 If temperature sensor do not match section 15.10, it must be replaced.
Err 86 Flue sensor shorted Check if temperature sensor match section 15.10 If temperature sensor do not match section 15.10, it must be replaced.
Err 87 Reset button error Too many reset button pushing in 60 sec
Err 93 Appliance selection error Check the list of 3000 parameters (Section 19)
