Check the condition of the hydraulic
circuit.
Leaking safety valve
Absence or incorrect size of the
expansion tank (unless the leak
is continuous)
Installation or correct pressure in the
expansion receptacle.
High water pressure (unless the
leak is continuous)
Check the pressure control
valve (if
installed).
Install a pressure control
valve (if not

Power consumption is
abnormally high and
constant
Leak or blockage of the coolant

Too fast magnesium anode
consumption
Magnesium anode wears in time. This wear is normal and prevents
corrosion in the tank. Wear rate varies depending on the water quality.
It is advisable to check the condition of the anode at least once every 2
years.
MAINTENANCE OF THE APPLIANCE
Prior to carrying out any maintenance work on the appliance, make sure that the appliance
is not powered.
Wait until the fan stops completely.
The liquid in the appliance may ONLY be handled by a qualified technician.
Although the coolant in the cooling circuit is ecological, it must not be discharged freely into the
environment.
Ecological disposal must be ensured.
