Pool Heater Short Cycling in Chula Vista, CA
When a Chula Vista pool has a pool heater that keeps shutting off, the fix is usually straightforward once the cause is found. A heater that fires then quits after a minute usually has a flow, pressure-switch, or high-limit fault rather than a dead unit. Chula Vista runs on Sweetwater Authority / Otay Water District at 12-16 gpg, which is hard water. Around here that means a split market of aging west-side plumbing and hard-water equipment strain out east, and it shows up in problems exactly like this one.
Likely causes in Chula Vista
- Low water flow tripping the high-limit or pressure switch
- A dirty filter or closed valve restricting flow
- A failing thermal regulator or flow sensor
- Scale in the heat exchanger from hard water
- A venting or airflow problem on the burner
What to check before you call
- Confirm the pump runs strong and the filter is clean
- Open any valves that feed the heater fully
- Note the error code when it shuts down
- Check for debris blocking the heater intake or vent
