How to troubleshoot HEAT PUMP FLOW

When the HEAT PUMP FLOW error message appears on your spa controller keypad, it indicates that there is either no water flow or an insufficient water flow passing through the heat pump.

The flow switch must close within 30 seconds of the filtration pump operation. Once a flow error has occurred, even if the water flow has been re-established, the main power to the SV spa control must be reset before the heat pump operates again.

To fix this error, follow the instructions below.

For existing heat pump installs:

• Step 1. Check the spa water level is OK, and refill if necessary. (Licensed electrician only)
• Step 2. Clean or replace the filter cartridges.
• Step 3. If the spa has just been emptied/refilled, bleed air locks from the pipework.
• Step 4. Check filtration pump is working OK and has not seized.

For new heat pump installations:

• Step 1. Check that isolation and bypass valves have been positioned correctly to suit the filtration pump.
• Step 2. Check the spa water level is OK and confirm that water is flowing freely into the filter area.
• Step 3. Check there is adequate water flow. If no flow, bleed air locks from pipework
• Step 4. Inspect pipe work and follow flow direction to ensure water is flowing out of the spa into the bottom inlet pipe on the heat pump, flowing out of the top outlet pipe on the heat pump and returning to the spa. If the heat pump has been plumbed in the reverse direction, correct plumbing or rotate the direction of the flow switch 180 degrees.
• Step 5. Check the filtration pump operation for internal thermal cut-out or motor stalls.

How to troubleshoot HEAT PUMP LOW P

When the HEAT PUMP LOW P error message appears on your spa controller keypad, it indicates either a lack of signal from the low-pressure switch or an insufficient refrigerant gas charge.

To fix this error, follow the instructions below.

• Step 1. Ensure the low-pressure switch is connected to the heat pump PCB. (Licensed electrician only)
• Step 2. Check the refrigerant level. If it is low, consult a refrigeration technician to inspect and recharge the refrigerant.

How to troubleshoot HEAT PUMP HIGH P

The HEAT PUMP HIGH P error message indicates either a loss of signal from the high-pressure switch or that the refrigerant pressure is too high due to excessive heat.

To fix this error, follow the instructions below.

• Step 1. Check the high-pressure switch is connected to the heat pump PCB. (Licensed electrician only)
• Step 2. Check the water flow is OK (low water flow rates could cause high-pressure errors).
• Step 3. Confirm ambient air temperatures are within operational limits, and that the fan is working.

Important reminder:

• In extreme environmental weather conditions (ambient temp > 38°C), depending on the heat pump location & environment and nearby obstructions and airflow restrictions (e.g., fences, plants, walls).
• If the heat pump is used for COOLING, the refrigerant may exceed its working capacity and shut down on high-pressure error. To prevent this, the heat pump should only be used for COOLING at times of day/night when ambient temperatures are lower and before extreme hot weather.

How to troubleshoot HEAT PUMP COMP

The HEAT PUMP COMP error message indicates that the compressor has overheated or that the thermal cut-out signal is corrupted.

To fix this error, follow the instructions below.

• Step 1. Confirm ambient air temperatures are within operational limits, and that the fan is working.
• Step 2. Turn off the mains power, leave the heat pump for 45 minutes for the compressor to cool, and test again.
• Step 3. Inspect the data cable for damage and check that it is connected correctly to the SV spa control.
• Step 4. Replace the data cable if the problem is unresolved (use a double-shielded CAT5/CAT6 Ethernet cable).

How to troubleshoot HEAT PUMP EXCH

The HEAT PUMP EXCH error message indicates that the Water temperature in the heat exchange tank exceeds 50°C or the thermal cut-out signal is corrupted.

To fix this error, follow the instructions below.

• Step 1. Check the spa water level and ensure the water flow from the filtration pump is OK.
• Step 2. Clean or replace the spa filter cartridges to improve water flow.
• Step 3. Inspect the data cable for damage and check that it is connected correctly to the SV spa control.
• Step 4. Replace the data cable if the problem is unresolved (use a double-shielded CAT5/CAT6 Ethernet cable).

Additional troubleshooting guide

Should a problem occur the SV spa controller will temporarily disable the heat pump and put it into error, with the touchpad display scrolling an error message every 30 seconds.

Important reminder: There are no user-serviceable parts inside the heat pump. If a major error occurs please contact your spa reseller, service technician or a licensed professional for service.

How to troubleshoot if water is leaking from the heat pump

If there is humidity in the air, the heat pump will create condensation on the evaporator as part of the heat exchange process. This is normal.

The higher the humidity, the more condensation is created. It is not uncommon for the heat pump to produce many litres of condensation; hence it is recommended that the condensation drain be installed to direct the condensation runoff to a suitable location.

If water is leaking from the heat pump, you may follow these troubleshooting steps.

• Step 1. Confirm that the drain pipe work is not blocked and that the machine is mounted on a level surface.
• Step 2. If the water leaking from the machine is not from condensation, then all pipework and connections should be checked for damage and leaks.

How to troubleshoot no heat pump operation

• Step 1. Check SV spa controller settings.
• Step 2. Confirm that the H.PMP setting has not disabled the heat pump. Confirm ambient air temperature is within operational limits.
• Step 3. Check there is no hammer and spanner error symbol on the display. If an error symbol is present, wait for the error code to scroll every 30 seconds and take corrective action accordingly.
• Step 4. Check that the heat pump power source is OK. Check RCD safety switch has not tripped. Check power and data cables for signs of damage. Replace cables if damaged.
• Step 5. Inspect the internal heat pump PCB for damage or blown fuse. *(Licensed electrician only) *

Reminder: Ensure power is isolated and turned OFF before inspecting the heat pump. Work should be performed by a qualified person).

How to troubleshoot thermal cut-out errors

• Step 1. Check for poor filtration pump flow performance.
• Step 2. Confirm ambient air temperatures are within operational limits.
• Step 3. Confirm heat pump air space is clear and not obstructed by vegetation or objects.

How to troubleshoot not enough heating

• Step 1. First check the ambient temperature, and water temperature, and estimate the related heating capacity.
• Step 2. Check if the heat pump has a ventilation obstacle.
• Step 3. Check the general power supply is correct and that the amperage drawn from the heat pump is as expected.
• Step 4. Check the refrigerant inside is enough. If the level is low find the gas leakage and recharge the unit. Lots of ice formation on the evaporator.
• Check the temperature sensors are calibrated.
• Insufficient air flow – check the install location, confirm the fan is working and remove any debris on or near the evaporator.
