Deactivate then reactivate power to reset controls. The refrigerant system’s high-pressure switch is showing as open. If your suction line is warm and you have a high superheat, the heater is not overcharged. 2. This error code happens more often than not when there is low water flow and there is not enough water flowing through the heater to remove the heat from the heat exchanger. On heat pumps the indoor coil becomes the condenser in the wintertime and if you are not getting enough airflow across the indoor coil it with cause the high-pressure code problem. Also see high head pressure remedy. Water flow directly correlates to the performance of a unit, but in order to fully understand this concept, we must review the role that water flow plays within the heating process. The high- pressure control opens at 610 PSIG. This can indicate a loose or damaged communication cable. The standard NE Series unit is configured performance. Refrigerant Circuit Service Only by Qualified, EPA Certified Technician WARNING ! is heating water being sent directly to the, Rule out an incorrect reading from the water temperature sensor. This switch will auto-reset at a slightly lower pressure. Now open valve number of turns listed by model in Table1below. Determine if an insufficient amount of water is being supplied to the equipment. A fault code indicates a specific issue or condition that will require action before the equipment can resume operating. Of these, debris clogging or malfunctioning TXVs seem to be the most common problems. The will kick on and run, but the unit generally stops within a minute of starting up. Bad refrigerant high pressure switch. Failure to heed the following may result in injury or death. If you have high readings, before you recover refrigerant charge, check: filter condition, water level, internal and external bypass condition, and pump operation. Do not exceed maximum flow rate for your model. During this segment of the process, the refrigerant is converted into a gas and becomes highly pressurized in order to increase in temperature. As it cools, the refrigerant gas condenses back to a liquid at high pressure then rapidly expands thru a valve (3) back to the lower evaporating pressure. There is a risk of electric shock at … Heat pump is running but not heating pool. Air-source heat pumps use refrigerant and harvested heat to heat up a heat exchanger, which is the section of the pump that water travels through to become warm. If. A restriction in your refrigeration cycle like a bad TXV (thermostatic expansion valve) or a stopped up orifice can also cause high-pressure problems. Heat Exchanger Problems: The heat exchanger is built to be fairly durable, but it could still fall victim to corrosion due to chemicals in the pool. Started Saturday. 4. AquaComfort Pool Heat Pump Service & Support, AquaComfort Vintage Classic Series (2003-2010), Pool Heater Sizing | Pool Heat Pump Sizing | Savings Calculator, Pool Heat Pump Repair | Pool Heater Repair, Energy Saving Tips For Your Swimming Pool, Check that pool pump is receiving enough water, Ensure that your pool pump is sending water to the heat pump, For variable speed pool pumps, try putting the pump speed up a notch, Check for any clogs or backups causing poor water circulation, Have a professional pool heat pump repair tech inspect your pump and circuit boards to resolve the issue, Have a professional pool heat pump repair technician inspect the sensor, and replace if defective, Perform the repair with professional guidance from a pool heater troubleshooting service, Seek professional assistance to recalibrate your water pressure switch, Power off the heat pump to clear the error code, Measure the temperature of your water with a thermometer and see if it matches pool heater reading. Restart heat pump. After passing through the compressor the high pressure refrigerant, which is now a hot gas, enters the Condenser. Why Swimming Pool Heaters Warm Water Ready When You Are. Troubleshoot the low-pressure issue causing the error. A gas pool heater burns gas to heat water for your pool or spa, making it the ideal pool heating solution if you have low-cost access to natural gas or propane, or if you live in a location with high electricity costs. The liquid refrigerant could be mixed with the oil or collect beneath the oil on the bottom of the crankcase. Water circulation pump not on. The heat pump will not operate until incoming water temperature drops to 100° F or lower. The ON LED will flash twice every 2 seconds. Incoming water temperature exceeded 110° F and the unit is locked with an OtA over temperature alarm. High Freon pressure. The refrigerant system’s low-pressure switch is showing as open. Verify existing water temperature with an accurate thermometer. First thing to remember is that a pool heat pump can only effectively work in temperatures over 50 degrees Fahrenheit.
