4.4 Troubleshooting
Diagnostics
The boiler is equipped with an advanced self-diagnosis system. In case of a boiler fault,
the display will flash together with the fault symbol (detail 22 - fig. 1) indicating the fault
code.
There are faults that cause permanent shutdowns (marked with the letter "A"): to restore
operation, press the RESET button (detail 8 - fig. 1) for 1 second or use the RESET on
the remote timer control (optional) if installed; if the boiler does not restart it is necessary
to eliminate the fault indicated in the operation LEDs.
Other faults cause temporary shutdowns (marked with the letter "F") which are automat-
ically reset as soon as the value returns within the boiler's normal working range.

Circulating pumsp diagnostics
Some faults linked to the circulating pump are signalled by the LED located around the
speed selector (fig. 41).

Fault Cause
Fault Blocked rotor
Contact/winding Faulty winding
Under/overvoltage Supply side voltage too low/high
Excessive module tem-
Inside of module too hot
perature
Short circuit Motor current too high
The hydraulic system of pumps
Turbine operation is fed but the pump does not
have mains voltage
Dry running Air in pump
The motor turns with difficulty.
Pump operation not in accord-
ance with specifications (e.g.
Overload
high module temperature).
The speed is lower than in nor-
mal operation.
Cure
Activate manual restart or
contact Customer Service
Check the mains voltage and
conditions of use.

Check the mains voltage, the
water flow/pressure as well as
the environmental conditions
