Troubleshooting

•  Before you contact your retailer, please carry out these few simple checks using the following 

tables if a problem occurs.

•  If the problem persists, contact your retailer.
• 

: Actions to be performed by a qualified technician only

5.1 I Appliance behaviour

The appliance 

does not start 

heating straight 

away

• 

When the setpoint temperature is reached, the heat pump stops heating: the water temperature 

is higher than or equal to the setpoint temperature.

• 

When the water flow rate is zero or is not enough, the heat pump stops: check that the water 

is  circulating  correctly  in  the  heat  pump  (see  §  “2.2  I  Hydraulic  connections”)  and  that  the 

hydraulic connections are correct.

• 

The heat pump stops when the outdoor temperature falls below -12 °C.

• 

It may be that the heat pump has detected an operating fault (see § “5.2 I Error code display”).

• 

If you have checked these points and the problem persists: contact your retailer.

The appliance 

is discharging 

water 

• 

Often called condensates, this water is the moisture contained in the air which condenses on 

contact  with  certain  cold  mechanisms  in  the  heat  pump,  especially  on  the  evaporator.  The 

damper the air, the more condensates your heat pump will produce (your appliance may drain 

several litres of water per day). This water is recovered at the base of the heat pump and drained 

by the condensate drainage elbow (see § “2.2 I Hydraulic connections”).

• 

To check that the water is not coming from a leak in the pool circuit on the heat pump, shut 

down the heat pump and run the filter pump to circulate water in the heat pump. If the water 

continues to flow through the condensate drainage lines, there is a water leak in the heat pump: 

contact your retailer.

The evaporator 

is iced over

• 

Your heat pump will soon switch to its defrost cycle to melt the ice.

• 

If your heat pump cannot manage to defrost its evaporator, it will stop itself; this means that the 

outdoor temperature is too low (below -12 °C).

The appliance is 

"smoking"

• 

The appliance has come to the end of the defrost cycle; water has changed to gaseous state and 

passes through the grid.

• 

If your heat pump is not in its defrost cycle, this is not normal. Switch off and disconnect the 

heat pump immediately and contact your retailer.

The appliance is 

not working

• 

When the setpoint temperature is reached, the heat pump stops heating: the water temperature 

is higher than or equal to the setpoint temperature.

• 

When the water flow rate is zero or is not enough, the heat pump stops: check that the water is 

circulating correctly in the heat pump (see § “3.2 I User interface presentation”).

• 

The heat pump stops when the outdoor temperature falls below

 

-12°C or rises above +40°C.

• 

It may be that the heat pump has detected an operating fault (see § “5.2 I Error code display”). 

The appliance 

is working 

but the water 

temperature 

does not 

increase

• 

Check that the automatic filling valve is not stuck in open position; this will keep supplying cold 

water into the pool and will prevent the temperature from rising.

• 

There is too much heat loss: install a heat insulated cover on your pool.

• 

The heat pump is unable to capture enough calories as its evaporator is clogged with dirt: clean 

it to restore its efficiency (see § “4.2 I Maintenance”).

• 

Check that the external environment is not hindering the heat pump (see § “❷ Installation”).

• 

 Check that the heat pump is the right size for this pool and its environment.

The fan is 

running but 

the compressor 

stops from time 

to time with no 

error message

• 

If  the  outdoor  temperature  is  low,  the  heat  pump  performs  defrost  cycles  under  normal 

operation.

• 

The heat pump is unable to capture enough calories as its evaporator is clogged with dirt. Clean 

it to restore its performances (see § “4.2 I Maintenance”).

The appliance 

trips the circuit 

breaker

• 

 Check that the circuit breaker is correctly dimensioned and that the cable section used is 

appropriate (see § “1.2 I Technical specifications”).

• 

 The supply voltage is too low: contact your electricity supplier.
