15.10.2 - Diagnostics: errors “Err”
Error
Description of error
Checks
Solutions
Err 0
A sensor is outside the
field of measurement
Check that all the temperature sensors are in a
plausible field of measurement
Replace the sensor that is not in the correct tem-
perature field or replace the main board
Err 45
Software error inside
control board
Replace the command and control board.
Err 46
Software error inside
control board
Replace the command and control board.
Err 47
Software error inside
control board
Replace the command and control board.
Err 48
Software error inside
control board
Replace the command and control board.
Err 49
Software error inside
control board
Replace the command and control board.
Err 50
Software error inside
control board
Replace the command and control board.
Err 51
Software error inside
control board
Replace the command and control board.
Err 52
Software error inside
control board
Replace the command and control board.
Err 53
Software error inside
control board
Replace the command and control board.
Err 54
Flame heard at a time
when it shouldn’t be
there
Replace the command and control board.
Err 55
Software error inside
control board
Replace the command and control board.
Err 56
Software error inside
control board
Replace the command and control board.
Err 57
Software error inside
control board
Replace the command and control board.
Err 58
Software error inside
control board
Replace the command and control board.
Err 59 (*) Low water pressure error Check the system’s pressure and if necessary
increase it.
If the pressure detected is higher than that in
parameter 3022, replace the pressure gauge.
Err 60
Exhaust gases high
temperature error
A - Check the combustion output of the burner the
error is flagged up against, output must be above
that required by regulations.
B - Check that the exhaust gases temperature sen-
sor’s resistance matches the graph in section 16.13.
A - If the output is lower than that required by
regulations, try to clean the exhaust gases side and
water side of the heat exchanger.
B - If the sensor doesn’t match it must be replaced.
Err 61
Return temperature
higher than delivery
temperature
Check that the electrical resistance of the return sen-
sor matches the graph in section 16.13.
If the sensor doesn’t match it must be replaced.
Err 62 (*) Error in condensate level
sensor
A - Check that the condensate outlet duct is not
blocked;
B - Check the status of the condensate neutraliser;
A - Clear the condensate outlet duct of any block-
ages;
B - Replace the product contained in the conden-
sate neutraliser;
Err 64
Error in frequency signal
or error in WD commu-
nication
A - Check the frequency of the signal. It must be
between 55 and 65 Hz.
B - Check the earthing and that neutral is at 0 volt
A - If the frequency doesn’t fall between the values,
ask the electricity supplier. Otherwise, try to replace
the control board.
B - If the neutral isn’t at zero, the correct electric
power supply must be restored. If the neutral is at 0
Volt, try to replace the control board.
Err 65
Inverted polarity be-
tween live and neutral.
Check the correct polarity between live and neutral. Invert the polarity between live and neutral.
