Why is Your Pool Pump Not Working?

A pool pump not working is one of the most common pool pump problems. The pool pump is essential to keep your pool water filtered and healthy for swimming. Without a working pump, pool water can turn cloudy, algae may bloom, and the swimming pool quickly becomes unusable.

If you tried to fix your pool pump and now it won’t start, there could be several causes, ranging from a tripped circuit breaker to a blocked pump basket. Understanding common pool pump issues helps you troubleshoot and keep your pool in top condition.

Pool Smart, Horseshoe Bay’s local expert in pool construction, renovations, and pool maintenance, can help you diagnose and fix pool pump issues—fast!

What’s the Anatomy of a Pool Pump?

Knowing the anatomy of a pool pump gives you the edge in quick troubleshooting. Your pool pump consists of several main components: the pump body, pump basket, pump lid, impeller, and pump motor. Water from your pool enters through the suction side, is filtered through the pump basket, pushed by the impeller (which spins on the motor shaft), and then returned to the pool.

• Pump Basket: Traps debris before it enters the pump motor.
• Pump Lid: Seals the pump basket section.
• Pump Housing: Holds the basket and seals water flow.
• Pump Motor: Drives the impeller and powers water circulation.

Keeping these parts clean and in good shape is a big part of routine pool care and helps prevent common pool pump problems.

Pool Pump Won’t Start: What Should You Check First?

When the pool pump doesn’t turn on, start with these checks:

1. Power Source: Make sure the pool pump is plugged in, the power switch is on, and the circuit breaker hasn’t tripped. The circuit breaker is often the first culprit.
2. Pump Motor & Timer: Set the timer to manual and try to start the pump again.
3. Pump Lid & Basket: Remove the pump lid and check for debris blocking the pump basket or impeller.

If your pool pump isn’t turning or you hear nothing at all, rule out electrical and basic mechanical issues before you attempt more advanced troubleshooting.

Humming Pool Pump: What Does That Sound Mean?

If your pool pump sounds like it’s humming but won’t start, the issue could be a jammed or seized motor shaft, a blocked impeller, or a power supply problem. A single hum, but no water flow or pump running, suggests the motor may not be able to spin due to something stuck inside your pump.

A humming pool pump is often caused by:

• Debris wedged inside the pump basket and impeller.
• Motor seized from lack of use or age.

Turn off the pump and disconnect power before checking inside the pump body. Clear any debris and gently turn the motor shaft by hand if possible.

Is Your Pool Pump Sucking in Air?

Air entering the pool pump disrupts water flow and causes noisy operation or loss of suction. Pool pump is sucking in air if you notice bubbles coming from the pool returns or hear gurgling inside the pump.

Common causes:

• Pool water level is too low.
• Pump lid o-ring is loose, cracked, or missing.
• Leaks around the pump lid or on the suction side (check the plumbing).
• Simply refill your pool water to the correct level or replace the pump lid o-ring. Ensure the pump lid is tight and seals well. These tips for your pool pump keep the system primed for best performance.

Is Your Pool Pump Leaking or Has Leaks Around the Pump Lid?

A pool pump is leaking if you see water coming from the pump housing, pump lid, or the middle of the pump body. Leaks can lead to low water flow into the pump and even cause the pump to run dry, risking motor damage.

Checklist:

• Check your pump lid for cracks or worn o-rings.
• Look for moisture around your pump lid and the pump housing.
• Inspect the plumbing and fittings entering and leaving the pump.

• If your pool pump is leaking, Pool Smart’s experts—with advanced Leaktronics equipment—can pinpoint and repair leaks, helping you maintain pool water and pool equipment health.

Does Your Pump Motor Overheat or Trip the Circuit Breaker?

Pool pump motor overheating is a warning sign. Excess heat generated by the motor may trip the circuit breaker or fuse, protecting your pump motor from burns or further damage.

Check for:

• Debris blocking the motor shaft or impeller spins.
• Clogged pump basket or poor water flow into the pump.
• Bad internal wiring or aged motor.

If your circuit breaker keeps tripping when you turn on the pump, stop using it and call a pool professional. Pool Smart helps troubleshoot both electrical and mechanical pool pump issues for safe and reliable operation.

Pump Basket, Impeller, and Pump Housing — Are They Clogged?

A clogged pump basket or blocked pump housing can make your pool pump not work or reduce performance. Always turn off the pool pump and disconnect power before removing the pump lid and pump basket.

Steps:

1. Remove and clean the pump basket.
2. Check inside the pump housing for objects or debris.
3. Inspect the impeller by reaching carefully into the middle of the pump body.

If you spot large debris or the impeller isn’t free to turn, clear the blockage and reassemble everything carefully. Regular cleaning helps prevent common pool pump problems!

Three Signs Your Pool Pump Needs Immediate Attention

Here are three common reasons why pool pumps fail and what to look for:

1. Unusual Noises: A loud hum, screeching, or grinding coming from your pool pump.
2. Leaks: Water consistently around or under the pump, especially near seals and connections.
3. No Water Flow: The pump running, but no water from your pool moves through—the pump is starved for water or the suction side is clogged.

When these signs appear, don’t delay. Turning on a faulty pump can cause further damage to your pool pump system and swimming pool water.
