Waterway pool pump trips the circuit breaker immediately when turned on.

Safety: Do not repeatedly reset a breaker that trips instantly. Turn off power and lock out if possible.

• Inspect cable and junction box: Check the power cable from the panel to the Waterway pump for cuts or crushed sections. Open the motor junction box and look for water, corrosion, or pinched wires.
• Test insulation: With power off and wires disconnected, use a megohmmeter (if available) to test resistance from each motor lead to ground. Low resistance indicates a ground fault.
• Check wiring connections: Verify that line conductors are correctly landed on L1 and L2 and not touching each other or ground.
• Dry and reseal: If moisture is present, dry the area thoroughly and reseal with proper gaskets and strain reliefs. If the motor still trips the breaker, replace the motor.
