Understanding Hayward Pool Heater Error Codes Lo

Hayward pool heaters are reliable and efficient systems that can heat a pool quickly. However, like all pieces of machinery, they can develop issues that require troubleshooting. One common problem is a Hayward pool heater error code Lo, which means the system has detected a low temperature in the water. In this article, we’ll discuss what causes this error code and how to troubleshoot it.

What Causes an Error Code Lo?

An error code Lo indicates that the water temperature has dropped below the set point of your heater. This could be due to a number of different factors, including:

  • Poor Pool Insulation If your pool’s insulation is insufficient or damaged, water can lose heat more quickly than it should.
  • Leaking Pipes If there are any leaks in your pipes, this can lead to cooler water and an error code.
  • Inaccurate Thermostat Settings Make sure your thermostat is set correctly for your desired temperature.

How to Troubleshoot an Error Code Lo

If you’re getting an error code Lo on your Hayward pool heater, there are a few steps you can take to try and resolve the issue:

  • Check Your Thermostat Settings:
    Make sure your thermostat is set correctly for the desired temperature of your pool.
  • Check Your Pool Insulation:
    If your insulation is insufficient or damaged, it’s likely causing your water temperature to drop too low. Make sure all insulation is in place and intact.
  • Check for Leaks:
    Look for any signs of leaks on pipes or around fittings. If you find any leaks, repair them as soon as possible.

Conclusion

An error code Lo on a Hayward pool heater indicates that the water temperature has dropped below the set point of your heater. This could be due to poor insulation, leaking pipes or inaccurate thermostat settings. To solve this issue, make sure all insulation is in place and intact, check for any signs of leaking pipes and ensure that thermostat settings are correct.

What are Hayward Pool Heater Error Codes?
