Pump starts then quickly shuts off with E02 displayed on the Harris digital control panel

Safety first: Shut off power at the breaker and close suction and return valves before opening the pump.

• Inspect for mechanical blockage: Remove the pump lid on the Harris strainer housing, take out the basket, and check for rocks, toys, or heavy debris. Reach into the wet end and feel for obstructions around the impeller eye.
• Check impeller rotation: With the pump drained and power OFF, access the rear of the motor and try to rotate the shaft by hand. It should turn smoothly. If it is hard to turn or locked, the impeller or bearings may be seized.
• Verify wiring and voltage: Confirm the pump is wired for the correct voltage (115V vs 230V) per the Harris motor wiring diagram. Use a multimeter to ensure the supply matches the selected configuration. Incorrect voltage can cause overcurrent trips.
• Clean the impeller: If blockage is suspected, remove the motor from the pump housing, unscrew the impeller from the shaft, and flush out any debris from the vanes. Reassemble with a new shaft seal if needed.

If E02 persists after clearing obstructions and verifying voltage, the motor windings may be damaged and the motor assembly should be replaced.
