FAULTS
As soon as a fault occurs, the appliance enters into the fault mode while the display emits flashing signals and visualises the error code. The wa-
ter heater will continue supplying hot water if the fault affects only one of two the heating units, by activating the heat pump or heating element.
If the fault involves the heat pump, the symbol "HP" will flash on the screen, while the heating element symbol will flash if the fault involves it. If
both components are affected, both symbols will flash.
CAUTION!
Before intervening on the product by following the indications below, check the correct electrical connection of the components to the
