Common Signs You Need a New Motor

• Motor hums but won’t start, or starts intermittently
• Loud bearing noise/squealing or excessive vibration
• Overheating or frequent thermal trips
• Breaker/GFCI trips (after confirming wiring/capacitor issues where applicable)
• Visible corrosion or water intrusion damage

Installation Notes

• Match by pump model and total horsepower (THP). “2 HP max-rate” is not interchangeable with every “2 HP” label across brands/series.
• Confirm your existing motor has a threaded shaft and the same mounting/frame style.
• When replacing a motor, it’s strongly recommended to also replace the shaft seal to help prevent leaks into the new motor.
• Shut off power at the breaker before servicing. If you’re not comfortable with electrical wiring, use a qualified professional.

Maintenance Tips

• Fix shaft seal leaks immediately—water intrusion is one of the fastest ways to ruin a motor.
• Keep the equipment pad ventilated and avoid trapping heat around the motor.
• Maintain clean baskets and a clean filter to reduce motor load and overheating.
• Winterize properly—freeze damage and trapped water can lead to costly wet-end and motor failures.
