FC Series Troubleshooting
A high refrigerant pressure error is typically caused by insufficient water circulation.
Ensure the skimmer is not clogged.
Confirm that the circulation pump basket is clear.
Perform a backwash if necessary.
Make sure the diverter valve is in the closed position, and the water inlet and outlet valves are open.
Verify that the circulation pump is functioning normally.
If the problem persists, please contact us.
If three high-pressure readings occur within an hour, reset the circuit breaker or press the Power button for 5 seconds.
A low-pressure error is usually caused by a leak, but it is important to perform some checks:
Ensure the fan is operating properly.
Confirm that the evaporator is not blocked.
If the error code appears three times within an hour, please contact us and take the following precautions:
Turn off the circulation pump.
Open the bypass valve.
Close the water inlet and outlet valves.
After these steps, you can restart the circulation pump. If the circulation pump is controlled by the heat pump, it will automatically shut down. You will then need to reset the circuit breaker or press the Power button for 5 seconds to complete the process.
A water flow error generally indicates that no water is circulating inside the heat pump.
Ensure the circulation pump is running.
Confirm there are no obstructions in the water filtration system (skimmer, filter pump).
Verify that the diverter valves
A compressor anomaly indicates that the compressor does not start despite a heating request.
If the issue persists, please contact us.
A water inlet temperature sensor anomaly indicates that it is disconnected.
Please check the sensor connection. If the issue persists, contact us.
Water inlet probe error, short circuit
A water inlet temperature sensor malfunction indicates that it is short-circuited or defective.
Please check the sensor connection. If the issue persists, contact us.
An air temperature sensor malfunction indicates that it is disconnected.
Please check the sensor connection. If the issue persists, contact us.
An air temperature sensor malfunction indicates that it is disconnected.
Please check the sensor connection. If the issue persists, contact us.
A defrost temperature sensor malfunction indicates that it is disconnected.
Please check the sensor connection. If the issue persists, contact us.
A defrost temperature sensor malfunction indicates that it is short-circuited or defective.
Please check the sensor connection. If the issue persists, contact us.
This anomaly is generally caused by insufficient water circulation.
Ensure the skimmer is not clogged.
Confirm that the circulation pump basket is clear.
Verify that a backwash has been performed.
Ensure the diverter valve is in the closed position and the water inlet and outlet valves are open.
Make sure the circulation pump is operating normally.
Please note that you will receive a reminder notification once a week to perform the backwash.
Please note that you will receive a reminder notification every 60 days to clean your evaporator.

More answers
Insufficient or nonexistent water flow from the pool heat pump
The pool heat pump requires a minimum water flow to function correctly. Low or nonexistent water flow may cause the heat pump to malfunction. Some models will display an error code if water circulation is insufficient.
Power supply failure
Operational issues with the pool heat pump may be caused by power or electrical current problems. Power to the heat pump can be interrupted in the following situations:
A bad connection or faulty wiring causes the circuit breaker to trip.
Cracks or bulges in the capacitors prevent the heat pump from starting electrically.
Heat pump incompatible with the water capacity of your swimming pool
If your heat pump is running but not heating your pool water sufficiently, it may be a sizing issue. This means the heat pump may not be suitable for the volume of water that needs to be heated. Check with your supplier to ensure that your heat pump is appropriately sized for your pool.
Evaporator coil clogged or blocked
It is essential to keep the evaporator coil clear to maintain proper air circulation for the pool heat pump. If the coil becomes clogged or blocked, the heat pump will not be able to heat your pool effectively. Make sure to clean the coil regularly to ensure adequate airflow to the heat pump.
Low ambient temperature
In rare cases, certain heat pump models require a temperature above 32°F (0°C) to function properly. If the temperature is too low, your heat pump may not be able to heat the water effectively or may not heat it at all.
Problem with the refrigerant pressure
The refrigerant in the heat pump is essential for heat production when compressed by the compressor. If the pressure is too low or too high, the heat pump may not heat effectively:
Low Pressure: Usually indicates that the ambient temperature is too low for the pool heat pump to operate efficiently.
High Pressure: Often signals a water flow issue, meaning there isn’t enough circulating water to transport heat effectively.
Incorrect setting of the thermostat
If the heat pump is running but not heating your pool, the thermostat may be set incorrectly. Ensure that the heat pump thermostat is set higher than the pool water temperature for optimal performance.
Insufficient operating time
The heat pump requires adequate run time to heat the pool water effectively. For best results, it is recommended to run the heat pump continuously for several days.
