Solution
• Check the sensor's connections.
• Check the wiring harness.
• Check the sensor.
• Check the operation of the pump.
• Check the wiring harness.
• Check that the fl ow and return heating isolation
valves are open.
• Fill the installation.
• Purge the installation.
• Check the pump connections.
• Check the fl ow and return heating sensor
connections.
• Check that there are no leaks.
• Check the fl ow and return heating sensor
connection.
• Check the pump speed.
• Check that the fl ow and return heating isolation
valves are open.
• Check the gas valve connections.
• Check the operation of the gas valve.
• Check the operation of the condensate pump (option).
• Check the fl ame detection electrode.
• Check the main board.
• Check the igniter unit.
• Check the return gas circuit (gas valve open).
• Check the observe the fl ame picture and check
the CO setting.
2
• Check the igniter unit connections.
• Check the state of the electrode (corrosion).
• Check the entire fl ue system.
• Check the fan's electrical connections.
• Check that the eBus controls are fi tted and wired
correctly.
• Check the main boards connections.
• Check the main board.
• Check the appliance DSN number is correct.
• Reset the appliance.
• Check the return gas circuit (gas valve open).
• Check the observe the fl ame picture and check
the CO setting.
2
• Check the igniter unit connections.
• Check the state of the electrode (corrosion).
• Check that the appliance DSN code on the screen
matches the product code of the nameplate (in the
event of a fault and the appliance DSN does not
appear, consult menu.d.93 reserved for the code).
• Check the boards reference.
• Check the sensor connections.
• Make sure that the sensor is clipped to the tube.
• Check temperature sensors connections.
• Replace faulty sensors.
