What Overheat means
High internal temperature, from a blocked cooling fan or very hot air. The pump slows down to cool off.
Likely causes
- Blocked cooling fan
- Pump in direct sun or an enclosed space
Safe first checks
- Clear leaves or debris away from the motor's cooling fan and vents, and make sure air can circulate around the pump.
When to stop
If it keeps overheating, have a pool pro check it.
