Err 53
Fumes 1 sensor circuit
(1006) open
Check that the electrical resistance of the exhaust flue
sensor 1006 matches the graphics in chapter 8.22
Check that the wires between the board and the
double exhaust flue sensor are connected correctly
If the sensor does not match, the double exhaust
sensor must be replaced.
If the wires are not connected correctly, the connec-
tions must be restored.
Err 54
Fumes 2 sensor circuit
(1014) open
Check that the electrical resistance of the exhaust flue
sensor 1014 matches the graphics in paragraph 8.15
Check that the wires between the board and the
double exhaust flue sensor are connected correctly
If the sensor does not match, the double exhaust
sensor must be replaced.
If the wires are not connected correctly, the connec-
tions must be restored.
Err 55
Not applicable
Err 56
Cold water inlet sensor
circuit(1007) in short
circuit condition
Check that the electric resistance of the sensor
matches the graphics in chapter 8.15. Check the
electric cables for connection between the sensor
and the command board.
If the electric resistance does not match, replace it.
The electric circuit must be repaired if it is damaged.
Without either of the two previous cases, replace the
command and control board.
Err 57
Domestic hot water inlet
sensor 1 circuit (1001) in
short circuit condition
Check that the electric resistance of the sensor
matches the graphics in chapter 8.15. Check the
electric cables for connection between the sensor
and the command board.
If the electric resistance does not match, replace it.
The electric circuit must be repaired if it is damaged.
Without either of the two previous cases, replace the
command and control board.
Err 58
Domestic hot water inlet
sensor 2 circuit (1005) in
short circuit condition
Check that the electric resistance of the sensor
matches the graphics in chapter 8.15. Check the
electric cables for connection between the sensor
and the command board.
If the electric resistance does not match, replace it.
The electric circuit must be repaired if it is damaged.
Without either of the two previous cases, replace the
command and control board.
Err 59
Domestic hot water inlet
sensor 2 circuit (1002) in
short circuit condition
Check that the electric resistance of the sensor
matches the graphics in chapter 8.15. Check the
electric cables for connection between the sensor
and the command board.
If the electric resistance does not match, replace it.
The electric circuit must be repaired if it is damaged.
Without either of the two previous cases, replace the
command and control board.
