temperature >89°C. Unit will NOT stop
operating. Automatic reset.
To solve the error code
INFORMATION
It is recommended to perform the checks in the listed
order.
1 Check the water circuit for an external heat source. See
"3.3 Water circuit" on page 95 .
Possible cause: Increased water temperature due to an
external heat source.
2 Perform a check of the domestic hot water tank thermistor. See
"2.23 Thermistors" on page 82 .
Possible cause: Faulty domestic hot water tank thermistor.
3 Perform a check of the hydro PCB. See "2.14 Hydro PCB" on
page 58 .

To solve the error code
1 No specific check / repair procedures must be performed to
solve this error code. The water in the heating system and the
tank is too cold to perform defrost operation, so the tank needs
to be preheated electrically. Wait until preheating operation is
done.
INFORMATION
If all procedures listed above have been performed and the
problem is still present, contact the helpdesk.
1.4.37 F3-00 – Discharge pipe temperature stop
abnormality
Trigger Effect Reset

operating. Automatic reset when
temperature drops
normal level.
If the error re-occurs
too soon: unit will
stop operating. Manual reset via user
interface.
