Possible Causes

Intermittent power supply, Loose breaker or lugs, Utility brownouts, Faulty breaker

How to Fix / Troubleshooting

Safety first: Turn off power at the breaker before tightening any electrical connections.

  • Inspect breaker: Ensure the breaker feeding the Hayward pump is not tripping or loose. Replace if it feels spongy or will not reset firmly.
  • Tighten lugs: With power off, tighten the line and load lugs at the breaker and any intermediate junction boxes.
  • Dedicated circuit: Confirm the pump is on a dedicated circuit sized per Hayward’s recommendations.
  • Monitor voltage: A qualified technician can monitor voltage at the pump during startup to detect dips or interruptions.
  • Utility issues: If PF occurs during neighborhood brownouts, consult your utility or consider a line conditioner.
