Category: Pool Pump After Storm

Power surges, lightning strikes, and the extended outages that follow storms are among the leading causes of unexpected pool pump failures. A pump that ran fine before a storm may not start after one — and the cause is almost always electrical, not mechanical.

The diagnostic sequence after a storm is specific: start with the GFCI reset and breaker, then check the timer settings (power outages reset mechanical timers and wipe programmable ones), then test the capacitor (surges kill capacitors), and finally check for motor winding damage with a multimeter. A pump that hums but won’t spin after a storm points to the capacitor in most cases. A pump with no response at all needs the power supply verified before touching anything internal. This section covers storm-related pool pump failures, surge damage diagnosis, timer reprogramming after outages, and what to do when the pump simply won’t respond after power is restored.
