DUE
The Manufacturer reserves the right to make technical or aesthetic changes to the products at any time without notice.
The drawings, measurements, diagrams and any other configurations are given only by way of example.
Fault
-The combustion chamber is dirty.
-The fume duct is obstructed.
-The fire door is not closed.
-The overpressure valves are open-stuck.
-Faulty vacuum switch.
-The combustion chamber is dirty.
-The fume duct is obstructed.
-The fire door is not closed.
-The overpressure valves are open-stuck.
-Faulty air flow meter.
-Occurs when the pressure transducer on
the water circuit detects a pressure below
or above the fixed limits.
-The safety thermostat has detected a
temperature above the setting threshold
due to overheating of the heating chamber
water blocking gearmotor operation.
-The controller detects a faulty gearmotor
control relay (contacts stuck).
-Faulty probe
-The probe is disconnected from the board.
-Occurs when the temperature probe in the
heating chamber detects a value above
92°C.
-Faulty probe
-The probe is disconnected from the board.
-Occurs when the temperature probe in the
heating chamber detects a value above
92°C.
-Faulty probe
-The probe is disconnected from the board.
-Occurs when the temperature probe in the
heating chamber detects a value above
92°C.
-Reset attempt in shutdown stage with
stove hot in cooling stage.
-The controller does not detect the amount
of combustion air and does not shut down
the stove; it only excludes the air flow
meter functions.
-The stove controller detects the water
temperature below 6°C and displays a
message.
-Extraordinary maintenance notice.
Possible causes
59
Cures
-Check cleanness of the fume duct and
combustion chamber.
-Check hermetic closing of the door.
-Check closing of the overpressure valves.
-Other reinstatement operations must be
carried out by a service centre.
