Pool heaters are an essential part of any swimming pool owner’s life. They provide warmth and comfort for swimmers and guests alike.
However, there are times when your pool heater may malfunction or stop working altogether.
Here are some tips to help you troubleshoot a Hayward pool heater if you are in such a situation.
Note: Most of these steps will apply if you own a different brand.
Before You Blame Your Pool Heater...
Checking the Pool Heater Circuit Breaker
First, turn off the power to the pool heater circuit breaker. This should immediately shut down the pool heater. If the circuit breaker does not shut off, you should call a professional service technician to come out and inspect the problem.
Next, check the fuse box located near the pool pump. The fuses should be in good condition. If one of the fuses has blown, replace it.
Check the Pool Heater Thermostat
Next, check the thermostat. If the temperature setting is set too low, the pool heater will not run properly. On the other hand, if the temperature setting matches the current temperature inside the pool, then the thermostat is functioning correctly.
Check the Pool Pump

Fixing A Hayward Pool Heater: Most Common Repairs

Here are some tips to keep in mind when maintaining a pool heater:
Clean The Filter Regularly

Check The Pool Pump And Water Level

How Do I Reset My Hayward Pool Heater?
You can reset a pool heater from the circuit breaker or control panel. This way, you do not have to call a technician to fix anything.
The control panel and keypad offer the same functionality; however, the keypad works better because there is no chance of making mistakes.
You need to press the control panel’s reset button to do this. Once you do, wait for about five minutes before turning the power supply back on again.
When you turn off the power supply, you will see a flashing red light.
After three seconds, the flashing red light turns green.
Then, you can turn the power supply back on.
Hayward Pool Heaters: Common Error Codes
bD - Gas valve error
This code means there is something wrong with the gas valve. The gas valve could be stuck closed, causing no heat output whatsoever.
This may happen because of corrosion, dirt buildup, or debris entering the valve. To check the gas valve, turn off the power, open the cover and look inside the valve.
You’ll see the valve stem sticking out of the housing. Remove the valve cap and clean the valve stem. Then replace the valve cap and reattach the power cord. Turn the power back on and test again. If the problem persists, contact a pro.
HF - Flame is sensed, but the gas valve is OFF
The flame sensor detects whether the burner is operating properly. If the flame isn’t burning brightly enough, the gas valve won’t operate. Check the flame sensor itself first.
Is it plugged in correctly? Does it work when the power is turned on? Is the battery fully charged?
PF - Electrical supply wiring error
The pool heater won’t function properly if the electrical supply wiring is faulty. The electric wires must pass through the wall outlet box. Ensure the wire connectors are securely attached to the wires and that the wires are firmly secured within the outlet box.
Also, make sure the breaker panel is set up correctly. If you notice loose connections, tighten them immediately.
