Trouble Shooting & Error Codes
My unit isn’t working
- Is the screen of control panel lit? If not, make sure the electrical wires and cables are correctly connected and the power is on. Ensure any circuit breaker devices are set to the ON position and press the ON button on your controller. Check your controller cable is plugged in and is not damaged. If the unit has been shut off or the power has been interrupted the heater will not restart for a 5-minute period to protect the compressor. Wait 5 minutes before attempting a restart.
- Three Phase units – If you are not getting any display on the controller make sure that the phase relay in the heaters electrical box is showing both lights (Green and orange). If both lights aren’t lit change the phases around until they are. The unit should now be functional.
- Is there sufficient water flow? If the screen displays a water flow related error check the water flow. Is the water pump in operation and the system free of debris that may cause a blockage? Disconnect pool cleaners to ensure proper water flow. Check and clear any skimmer boxes.
- Is the current pool/spa water temperature higher than the set temperature on the controller? If so the unit will not operate until the pool/spa water temperature falls below the set temperature on the controller.
- Check the controller for error messages and refer to the error code table.
My unit is running but not heating
- Is the unit in “Heating” mode?
- Is the air discharged from the front of the fan noticeably cooler than the ambient temperature? If not, check to see if the WATER OUT temp is higher than the WATER IN temp. Check also the INLET WATER TEMP is lower than the HEAT TEMP set point.
- Ensure sufficient fresh airflow around the unit as per installation instructions. Make sure cold air discharged does not recycle back through the heater. Check the condenser fins. If they are dirty or blocked use a low flow garden hose only (pressurised water may cause damage to the heater).
- The unit will periodically defrost when the ambient air temperature is lower than 8 degrees C.
My heater is running continuously
- Check the set temperature is at your desired level and that the pool water temperature is at or below this set point.
- Possible electrical component failure – contact EVOHEAT on 1300 859 933
Water appearing around unit base
- Condensation is a normal by product of running a pool heat pump.
- Possible water leak. Check the discharge for the presence of chlorine. If the water has no chlorine then it is condensation and is normal. Another method of checking is to turn the heater off and run the water pump continuously for a period of 2-4 hours. If the water dries out then it was condensation. If there is a continuous leak contact EvoHeat for service on 1300 859 933.

The E03 error is usually caused by poor/no water flow.
As a first step check when you are getting this error – if it is when the system is off this is normal and the error will clear when water flow resumes.
If you are getting this error when the system is on and running then it is a case of checking that you are getting enough water flow to the unit. For example clear your skimmer, pump, filter and ensure any valves are in place correctly.
If you have ensured good water flow and the system is on and you are still getting this error please call the Evo Heat Service team on 1300 85 99 33.
Do I need to get my unit serviced?
It is recommended that you get your EvoHeat unit serviced once a year by your local certified air conditioning or refrigeration technician. If your unit is located in a coastal area, more frequent maintenance may be necessary. During the service, they will check the operational pressures of the refrigeration system and give the unit and fins a good clean to ensure maximum performance.
Do we have recommended service agents? EvoHeat have a large database of recommended service agents. Please contact EvoHeat on 1300 859 933 for your local service agent details. Should I check my unit regularly?
We recommend you check your unit regularly to avoid potential issues and damage to your heat pump.
What should I be checking regularly?
Check the water inlet/outlets often for leaks. You should avoid the condition of no water or air entering into the system, as this will influence unit’s performance and reliability. You should clear the pool/spa filter regularly to avoid damage to the unit as a result of the dirty of clogged filter. The area around the unit should be dry, clean and well ventilated. Make sure there is nothing blocking the airflow of the heater e.g. Leaf litter. Discharge all water in the water pump and water system, so that freezing of the water in the pump or water system does not occur. You should discharge the water at the bottom of water pump if the unit will not be used for an extended period. You should check the unit thoroughly and fill the system with water fully before using it for the first time after a period of time. Check the power supply and cable connection often, should the unit begin to operate abnormally, switch it off and contact the qualified technician 
If your pool water is allowed to cool significantly, it may take several days to return to the desired swimming temperature. For weekend use, it is more economical to maintain the pool water temperature at or near your desired swimming temperature. If you do not plan to use your pool for a prolonged period, then you might choose to turn the heat pump completely off or decrease the temperature setting of the control several degrees to minimize energy consumption.
- Use an accurate pool thermometer. A difference of 2ºC, between 26ºC and 28ºC, will significantly increase energy consumption.
- Carefully monitor the water temperature of your pool in the summer time. You can reduce heat pump usage due to warmer air temperatures.
- When the pool is not used for long periods, turn off the heat pump.
- Where possible, shelter the pool from prevailing winds with well-trimmed hedges or other landscaping, cabanas, or fencing.
- Always use a high-quality pool cover when practical. Besides providing a valuable water saving feature, a pool cover will dramatically reduce heat loss and reduce your pool heating running costs by up to 70%.
