Pump attempts to start then shuts down within a few seconds, display shows E02

Safety first: Turn OFF the breaker and lock it out if possible. Confirm the pump cannot start while you are working.

• Check for mechanical blockage: Close suction and return valves. Remove the pump lid on the Franklin Electric wet end. Inspect the strainer basket and impeller inlet for stones, leaves, or plastic. Remove all debris.
• Spin the motor shaft: At the rear of the motor, remove the end cap or fan cover. Try to rotate the shaft by hand with power off. It should turn smoothly. If it is stiff or frozen, the motor bearings or shaft are seized.
• Inspect impeller: Separate the motor from the pump housing per Franklin Electric instructions. Check the impeller for wrapped debris (string, hair) or melted plastic. Clean or replace the impeller if damaged.
• Check supply voltage under load: With a meter and extreme caution, measure voltage at the control box while the pump tries to start. A large drop indicates undersized wiring or a weak supply.
• If shaft is seized or windings test bad: Replace the Franklin Electric pump motor assembly or have it rebuilt by a motor shop.
