Display shows E10 and pump will not start; sometimes accompanied by humming noise from motor

Safety first: Capacitors can hold a charge even with power off. Discharge them safely with a resistor before handling.

• Access capacitor compartment: Turn off power and remove the motor end cover where the capacitor is housed.
• Inspect capacitors: Look for bulging, leaking, or burned start and run capacitors. Check for loose spade terminals.
• Test capacitance: Use a capacitance meter to verify microfarad (µF) values against the Franklin Electric motor label. Replace any capacitor more than ±10% out of spec.
• Use correct replacements: Install capacitors with the exact µF and voltage rating specified by Franklin Electric. Secure them firmly.
• Reassemble and test: Restore power and start the pump. If E10 persists, the motor windings or centrifugal switch (if equipped) may be faulty and the motor should be replaced.
