Solution
- Contact the Technical
Assistance Centre
- Restore pressure
- Check for any leaks in the
system
- Check connections
- Check the sensor is
working
- Check connections
- Check the sensor is
working
- Check the integrity of the
electrode and check that it
is not grounded
- Check gas availability and
pressure
- Check the integrity of the
gas valve and the card
- Check the sensor or
thermostat connections
- Deaerate the system
- Check the bleed valve
- Replace the sensor or the
thermostat
- Check that the pump
impeller is not blocked
- Check the integrity of the
electrode and check that it
is not grounded
- Check the integrity of the
gas valve and the card
- Check the rotation of the
pump rotor
- Check the electrical
connections
- Replace the pump
- Check the hydraulic
configuration using "tS
0.2"
- Check the electrical
connection
- Check the electrical
connection
- Set the parameter
tS 0.4 (Combustion
configuration) to 0
- Check the sensor is
working
- Replace the smoke probe
- Replace the smoke probe
- Check the electrical
connection of the smoke
probe
- Contact the Technical
Assistance Centre
- Check the connection
cable between the fan and
the board
- Check for any clogging in
the pipe which takes the
condensate to the siphon
- Check that the siphon is
not clogged
- Wait 1 hour and try
unblocking the board
again
- Contact the Technical
Assistance Centre
