What to do if my Hayward EasyTemp ECPI15MA displays high pressure protection?
- E
  Erik WeaverAug 20, 2025
  If your Hayward Heat Pump shows a high pressure protection error, several factors could be the cause. You can check the water flow, inspect the water flow detector, and ensure the valve is opening correctly. Also, verify the bypass and make sure the evaporator isn't clogged. Other potential causes include the water temperature being too hot, incondensable issues after maintenance (in which case you should empty and evacuate the cooling circuit), or the fluid load being too high (remove fluid into a liquid bottle).

  Kristen MercerAug 22, 2025
  If your Hayward Heat Pump is showing a low pressure protection fault, there are several things to investigate. First, check the AI/DI03 connections on the card, and consider replacing the sensor if necessary. Other possible causes include a large coolant leak (search for the leak with the detector), insufficient airflow (check the ventilator rotation speed), or a clogged evaporator (clean its surface).

  If your Hayward Heat Pump is displaying a flow sensor fault, start by checking the AI/DI02 connections on the card. If the sensor is open or short-circuited, consider replacing it. Also, check for a lack of water, ensuring the filtration pump is operating correctly. Finally, verify the stop valve opening and check the bypass adjustment.

Why does my Hayward EasyTemp ECPI15MA Heat Pump show a water inlet sensor fault?
- F
  Frank CarterAug 26, 2025
  A water inlet sensor fault on your Hayward Heat Pump typically means the sensor is either open or has short-circuited. To resolve this, verify the CN21/RES1 connectors on the board and the extension connector, or replace the sensor.

What does it mean when my Hayward EasyTemp ECPI15MA Heat Pump displays an Input/Output temperature difference > 13°C?
- B
  Brent MartinezAug 27, 2025
  An Input/Output temperature difference greater than 13°C on your Hayward Heat Pump can indicate a few issues. It could be due to a lack of water, so check the filtration pump operation. Also, verify the stop valve opening and check the bypass adjustment.

What should I do if my Hayward EasyTemp ECPI15MA Heat Pump displays a fan motor fault?
- C
  Christine Burns PhDAug 30, 2025
  If your Hayward Heat Pump is showing a fan motor fault, check for a few potential issues. Ensure the fan can rotate freely and check the CN97/DC connectors. You may also want to check the DCFAN/CN97 connector. If these steps don't resolve the issue, consider replacing the motor.

What to do if my Hayward EasyTemp ECPI15MA displays antifreeze protection in Cold mode?
- D
  Dr. Anne VillanuevaAug 31, 2025
  If your Hayward Heat Pump is showing an antifreeze protection warning in Cold mode, it's likely because the water output temperature is below 4°C. You should stop the heat pump and empty the condenser to prevent the risk of freezing.

What does it mean when my Hayward Heat Pump shows Level 1 antifreeze protection?
- C
  Courtney MillsSep 2, 2025
  Level 1 antifreeze protection on your Hayward Heat Pump indicates that the water temperature is between 2°C and 4°C, and the air temperature is below 0°C. Stop the heat pump operation and empty the condenser to avoid freezing. By default, the heat pump starts the filtration pump to prevent icing over.

What does it mean when my Hayward EasyTemp ECPI15MA Heat Pump shows Level 2 antifreeze protection?
- M
  Melissa EvansSep 4, 2025
  Level 2 antifreeze protection on your Hayward Heat Pump means the water temperature is below 2°C and the air temperature is below 0°C. You should stop heat pump operation and empty the condenser to avoid freezing. By default, the heat pump starts the filtration pump and the heat pump to prevent icing over.

Why does my Hayward EasyTemp ECPI15MA Heat Pump stop when the exterior temperature is too low?
- M
  Michael WhiteSep 6, 2025
  If your Hayward Heat Pump stops due to a low exterior temperature, it means the operating limit has been reached. The suggested solution is to stop the heat pump.
