How to Troubleshoot a Submersible Pump That’s Not Working

Has your submersible pump suddenly stopped working, leaving you frustrated and unsure where to start? You’re not alone. As someone who has spent years in the water systems industry, I’ve seen firsthand how a malfunctioning submersible pump can disrupt daily life. At Crowns, we understand that urgency and have designed our pumps with both durability and ease of troubleshooting in mind. This guide will walk you through practical, step-by-step checks to diagnose common issues, and highlight how choosing a reliable brand like ours can minimize these headaches.

What Are the First Safety Checks You Must Perform

Before touching anything, always disconnect the submersible pump from its power source. Safety is paramount. Verify that the circuit breaker hasn’t tripped and that the outlet is functioning with another device. A simple power issue is often the culprit. Next, inspect the control box, if your model has one, for any visible damage or tripped thermal overloads. Our Crowns pumps are equipped with robust thermal protection, but external power inconsistencies can still cause interruptions.

Is the Problem Related to Water Supply or Pressure

A pump running but delivering little or no water points to different issues. First, check your system’s pressure gauge. Is it reading zero or below the cut-in pressure? This could indicate a clogged intake screen or a stuck check valve. For submersible pump models installed in wells, a drop in water level below the pump intake can cause dry running. Our pumps feature built-in dry-run protection, a core advantage of the Crowns design that prevents motor burnout in such scenarios.

Could Electrical Components Be the Hidden Culprit

Electrical failures are common. Use a multimeter to test for continuity in the pump’s cable and connections. Look for any cuts or abrasions in the wiring. The pump’s capacitor, often housed in the control box, can also fail. Refer to your manual for testing procedures. The superior insulation and connection specs of a Crowns submersible pump are engineered to withstand harsh environments, significantly reducing electrical fault risks.

How Do Your Product’s Specifications Aid in Troubleshooting

Understanding your pump’s key parameters makes diagnosis faster. Compare the actual performance against these designed specifications. Here are the critical parameters for a typical Crowns heavy-duty submersible pump:

• Motor Power: 1.5 HP

• Maximum Head: 120 feet

• Maximum Flow Rate: 25 gallons per minute

• Voltage: 230V, 1-Phase

• Built-in Protections: Thermal overload, Dry-run, Sand-resistant seal

When Should You Consider Professional Help or a Replacement

If all basic checks pass but the pump remains faulty, the issue may be internal, like a burnt motor or severe impeller damage. Continuous troubleshooting without expertise can cause further damage. If your pump is old, frequently malfunctions, or requires costly repairs, investing in a new, reliable unit is more economical. This is where the engineered resilience of a Crowns submersible pump proves its long-term value, offering peace of mind and consistent performance.
