Fault diagnosis and repair
In the event of a malfunction, first check
that the prerequisites for correct operation
are fulfilled:
1. is the system connected to the power
supply?
2. is there oil in the tank?
3. are all shut-off valves open?
4. are all control and safety devices,
such as the boiler thermostat, low-water
detector, limit switch, etc.
adjusted correctly?
If the malfunction persists, use the
following table.
It is not permitted to repair any
components relevant to safety. These
components must be replaced by parts
with the same order number.
Only use original spare parts.
NB: after each operation:
• under normal operating conditions
(doors closed, hood fitted, etc.), check
combustion and check the individual
lines for leaks.
• Record the results in the relevant
documents.
E-BCU display interface must be used
to read the faults by service personell.
