Pool Heater Short Cycling in Potrero, CA

If you are dealing with a pool heater that keeps shutting off in Potrero, you are not alone. A heater that fires then quits after a minute usually has a flow, pressure-switch, or high-limit fault rather than a dead unit. Potrero runs on Wells dominant at 14-18 gpg, which is very hard water. Around here that means wind-worn equipment and very hard well water on remote border ranches, and it shows up in problems exactly like this one. A specialist in the Refresh Pool Pros network can diagnose it on site in Potrero and quote the fix in writing before any work starts.

Can I fix a pool heater that keeps shutting off myself?

You can safely run the first checks: confirm the pump runs strong and the filter is clean, and open any valves that feed the heater fully. Anything involving wiring, gas, or a submerged fixture should go to a licensed Potrero pro.

Does Potrero's hard water make this worse?

It can. Potrero water runs 14-18 gpg, rated very hard, and scale from hard water is a real factor in problems like this. A pro will check for buildup as part of the diagnosis.
