Pool Heater Not Heating in Escondido, CA

A Escondido 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. Escondido runs on Escondido Water Utilities at 12-16 gpg, which is hard water. Around here that means scale-worn equipment and fire-season ash intrusion straining pumps and filtration on hillside properties, and it shows up in problems exactly like this one.

Likely causes in Escondido

  • 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
Typical Escondido fix cost $250 to $1,600
