Pool Heater Not Heating in Bonsall, CA
A Bonsall 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. Bonsall runs on Rainbow Municipal Water District at 14-18 gpg, which is very hard water. Around here that means aggressive calcium scaling from nearly pure Colorado River water eating away at plaster, tile, and pump seals, and it shows up in problems exactly like this one.
Likely causes in Bonsall
- 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
