15.14 - Diagnostic:
Blocking errors
"Err"
Blocking errors are generated by a
permanent fault. There is no way to
unlock the unit other than to resolve
the cause of the fault.
On multi-burner unit models 399 up
to 1000, when the burner goes into a
blocking error state, you'll see
Checks
Not needed
Check pressure sensor
Check pressure sensor
Check pressure sensor
Check pressure sensor
a - Check the pressure into the water system and eventually
increase it
high fire (see also Section 4.1);
b - Check the combustion efficiency of the burner in fail.
Combustion Efficiency must be higher than 88%;
c - Check the flue gas temperature sensor match Section
16.10.
a - Check if temperature sensor match Section 16.10
b - Check if supply and return pipe are reversed
a - Check if the condensate drain is blocked
b - Check if the condensate box is blocked
a - Check the frequency signal. It must be between 55 and
65Hz
b - Check the ground connection (between ground and neutral
it must be 0 volt)
Check supply voltage polarity
Check the frequency signal. It must be between 55 and 65Hz
Check the earth connection to the appliance
Check if temperature sensor match Section 16.10
Check that the primary heat exchanger temperature fuse has
not intervened.
Check if temperature sensor match Section 16.10
Check if temperature sensor match Section 16.10
Check if temperature sensor match Section 16.10
Check if temperature sensor match Section 16.10

a - If water system pressure is over parameter 3022, replace the water
pressure sensor
a - If return temperature is higher than 145°F (62°C) downrate the
capacity or reduce the water flow;
b - If combustion efficiency is lower than 88%, try to clean the flue gas
side and the water side of the heat exchanger;
c - If flue temperature sensor do not match Section 16.10, it must be
replaced.
If temperature sensor do not match Section 16.10, it must be replaced.
a - Remove any obstruction from the condensate drain
b - check the condensate box, if medium is exhaust it must be
replaced
a - If out of range, ask your electrical supplier.
b - If the ground connection is not right ask to your electrical supplier
Diversely try to replace the power contro board
Reverse supply voltage polarity, if it's the case
If out from range, ask your electrical supplier. Diversely try to replace
the power contro board
Repristinate the earth connection
Replace the power control board
If temperature sensor do not match Section 16.10, it must be replaced.
If the primary heat exchanger temperature fuse has intervened (the
contact is open), the exchanger must be replaced
If temperature sensor do not match Section 16.10, it must be replaced.
If temperature sensor do not match Section 16.10, it must be replaced.
If temperature sensor do not match Section 16.10, it must be replaced.
If temperature sensor do not match Section 16.10, it must be replaced.
