Why Is Hayward Pool Heater Control Panel Not Working?

There are multiple reasons behind the sudden malfunctioning of your pool heater. Moisture soaking into the control panel is a common one.

Apart from that, there can be issues like the heater burning out or it requires a service call. Let’s look at a few plausible reasons.

  1. Water Damage

If your pool heater is exposed to elements and you live in an area with extreme weather conditions, then it may have caused the malfunctioning.

If you recently had a rainy season in your area, the chances of moisture soaking in the heater are too high.

To check whether it is a communication error or not, check the gasket of your Hayward pool heater. If you find it compromised you can use a hairdryer to dry it out.




  1. Tripped Circuit Breaker:

Another common reason behind the malfunctioning of your Hayward pool heater is a tripped breaker. Once you have made sure there is no water damage then your next trip should be to the circuit breaker of the heater.

The control panel will stop working if a breaker has been tripped due to power overload. First, check whether the breaker is on or off. Just checking may not be enough.

To reset the breaker, turn it OFF first and then turn it ON again. Next check whether your pool heater is working or not.

  1. Improper Installation

If you own a new Hayward pool heater and the control panel is not working, we recommend checking the installation first. It is very important that the heater gets installed as per the manual.

The next step would be to check whether it is a power issue from your end or not. There may be a voltage issue occurring that you didn’t notice. Once you fix that, your new Hayward pool heater will work normally.


Final Words

With this elaborate guide, now you will know what to do if your Hayward pool heater control panel is not working.

Most Hayward pool heaters are very robust and last for a very long time. But they do require service checks from time to time. The control panel not receiving data is another sign of a service check.

If your pool heater is not facing any of the problems mentioned, then call Hayward services. It is certainly time for a service check.
