Problem
Possible Causes
How to Proceed
Too much usage of the
electric heater as a
backup (auto mode)
Low external temperature
The running of the equipment depends on
weather conditions
Low water temperature
The running of the equipment depends on the
inlet water temperature
Low voltage installation
Make sure the installation is supplied with the
indicated value for voltage
Heat pump Error
Check the error display in the electronic board
Evaporator blocked
Clean the evaporator
Fan blocked
Check the status of the fan (dust, wire…)
Low hot water flow
rate
Hydraulic circuit blocked
Check the condition of the hydraulic circuit
Water discharge on the
safety group
Absence or incorrect sizing of
expansion vessel (if leak is not
continuous)
Installation and/or correct dimensioning of
expansion vessel
High mains pressure (if leak is
continuous)
Check the reducing pressure valve (if installed)
Install a reducing pressure valve (if not
installed)
Power consumption is
abnormally high and
constant
Leak or obstruction in refrigerant
circuit
Check that the piping is not damaged
Dire environmental conditions
Electrical heater not
working
Safety thermostat ON
Check the condition of the thermostat
Defective electric heater
Check the electric heater
Bad odor
Absence of siphon or siphon
without water
Install and make sure the siphon has water
Undraining condensation
Drainage circuit blocked
Clean the condensation circuit
Drain pipe blocked
Check the draing pipe
Too quick consumption of
the Mg anode
Over time, the magnesium anode will be consumed. This consumption is normal,
resulting of scarification to prevent corrosion of the tank. The consumption rate
differs depending on the quality of your water. Is recommended to check the status
of your anode at least every year.
SYSTEM MAINTENANCE
Before undertaking any maintenance operation on the equipment, make sure it is not plugged
to the power supply!
Wait until the fan comes to a complete stop.
