Ferroli. Modena C HE fault codes

A01. No burner ignition

  1. Detection or Ignition electrode fault
  2. No Gas
  3. Defective gas valve
  4. Incorrect inlet pressure

A02.  Flame detection with the burner off.

  1. Ionisation electrode defection.  (check the ionising electrode wiring)
  2. Main board defective. (Check the PCB)

AO3. High Limit Protection.

  1. Flow temperature sensor not active or correctly
    located. Check the correct positioning and operation of the flow sensor.
  2. No system circulation. Check pump and radiator valves present in the system.Check operation of the internal by-pass.

A04. Flue gas fault

  1. Fault F07 happened 3 times in the last 24 hours. Check the flue

A05. Fan problem

  1. Tachometer signal interrupted for 1 hour or longer Check the wiring and the fan

A06. No flame after the ignition phase (6 times in 4 minutes)

  1. Detection electrode fault. Check that the electrodes are correctly positioned and if necessary change it
  2. Flame unstable. Check the burner
  3. Incorrect valve gas Offset. Check the Offset at the minimum power
  4. Flue gas circuit obstructed. Check if flue gas circuit is free
  5. Siphon obstructed. Check and if necessary change the siphon
