How to troubleshoot a Hayward HP70HA2 Heat Pump that is not operating?
- H
  hoffmandustinAug 10, 2025
  If your Hayward Heat Pump isn't operating, first ensure the power is on and check the breaker. If tripped, reset it. Make sure the thermostat is set high enough for the unit to turn on, and that the 3-minute compressor delay has passed. Check for low water flow by ensuring the filter is clean, the filter pump is on, and cleaning devices are unhooked. Also, verify the outside temperature is within the operating range. If the fan isn't working, call for service.

Why does my Hayward HP70HA2 run continually?
- M
  moorechristineAug 21, 2025
  If your Hayward Heat Pump runs continually, the thermostat might be set too high for the ambient temperature; try turning it down. The evaporator could be dirty; clean it by running tap water over the coil without any nozzle attachment. Avoid using pressurized water. If these steps don't help and you suspect an electrical component failure, turn off the pump. If the unit continues running after 3 minutes, turn off the power and call for service.

What to do if water is coming from the bottom of my Hayward Heat Pump?
- C
  Christian GreenAug 28, 2025
  If water is coming from the bottom of your Hayward Heat Pump, it might be condensation, which is normal. However, to check for a possible water leak, turn the unit off for several hours but leave the filter pump running. If the water quantity decreases, it's likely just condensation; otherwise, a leak might be present.

Why is my Hayward Heat Pump cycling (on / off too quickly)?
- L
  lesterjoseSep 3, 2025
  If your Hayward Heat Pump is cycling on and off too quickly, ensure sufficient water flow by checking if the filter pump is running continually. If the cycling continues, turn the unit off to prevent compressor damage. Also, inspect the evaporator coil for severe frost, which could indicate low refrigerant, low ambient temperature, or high humidity with low ambient temperature. If cycling persists, turn the unit off and call for service.
