• Overheating: Burning smell or excessive heat emanating from the pump
• Electrical issues: No power to the pump or intermittent operation
• Pump not starting: No response when the pump is turned on

Step-by-Step Troubleshooting Process

1. Check the Electrical System

• Verify that the pump is receiving power by checking the circuit breaker or fuse.
