Pump stops during operation and displays E02 on the Espa digital controller

Safety first: Turn off the pump at the breaker and allow it to cool for at least 30 minutes before handling.

• 1. Check motor ventilation: Inspect the motor body and cooling fins on the Espa pump. Remove leaves, dust, and cobwebs that may block airflow. Ensure the motor fan cover is not obstructed.
• 2. Verify installation location: Espa pool pumps should be installed in a well-ventilated, dry area. If the pump is in a closed box or under a cover with poor airflow, open vents or relocate the unit to improve cooling.
• 3. Inspect for hydraulic overload: Remove the prefilter lid and basket, clean debris, and check the impeller for obstructions. A partially blocked impeller can cause the motor to draw excessive current and overheat.
• 4. Check for voltage issues: Using a multimeter (only if competent), verify that the supply voltage at the pump terminals matches the Espa nameplate rating. Low or high voltage can cause overheating.
• 5. Test restart: After cleaning and cooling, restore power and restart the pump. If E02 recurs quickly, the motor windings or internal thermal protector may be failing and the motor assembly should be replaced.
