Pump runs for a short time then stops; motor housing is very hot to the touch, but there is no digital error display (on non-digital models).

Safety first: Turn off power and allow the motor to cool completely before touching it.

• Improve ventilation: Clear leaves, debris, or stored items from around the Emaux motor. Ensure adequate airflow and do not enclose the motor in a sealed box.
• Check for overloading: Verify that filter pressure is within normal range and that valves are correctly positioned to avoid excessive backpressure.
• Verify supply voltage: Have an electrician check that the supply voltage matches the motor rating; undervoltage can cause overheating.
• Allow cooling and reset: Many motors have an automatic reset; once cooled, they will restart. If the motor repeatedly overheats, internal damage may be present.

Persistent overheating indicates a need for professional evaluation and likely motor replacement.
