Pump is unusually hot to the touch on the motor housing, even though it is running.

Safety first: Use caution when touching the motor; surfaces can be very hot. Turn off power before cleaning vents.

• 1. Improve airflow: Clear debris from around the motor and ensure vents are unobstructed.
• 2. Reduce speed and runtime: On VS models, lower the RPM and consider running longer at lower speeds instead of short periods at maximum speed.
• 3. Check for bearing noise: Listen for grinding or whining that indicates bearing wear, which increases heat.
• 4. Monitor temperature: Some warmth is normal, but if the motor is too hot to touch briefly or trips thermal protection, further evaluation or motor replacement may be needed.
