Pool Heater Not Heating in Granite Hills, CA
A Granite Hills pool showing a pool heater that will not heat usually has a short list of likely causes. No heat, short cycling, or an error code usually points to ignition, gas or airflow, or a scaled heat exchanger. Granite Hills runs on Helix Water District at 16-20 gpg, which is very hard water. Around here that means decades-old plaster and extreme mineral scale pushing equipment past its expected life, and it shows up in problems exactly like this one.
Likely causes in Granite Hills
- Failed igniter, flame sensor, or pressure switch
- Insufficient water flow tripping the high-limit
- Scale buildup inside the heat exchanger from hard water
- Gas supply or valve problem on a gas heater
- A failing control board on an older unit
What to check before you call
- Confirm the pump is running and flow is strong
- Check the thermostat is set above current water temperature
- Look for an error code on the display and note it
- Clear leaves and debris from around the heater intake
