If your Bestway pool pump isn’t working the way it should, don’t panic. Bestway pumps are simple, reliable machines—but like any equipment, they can run into problems over time. Whether it’s not turning on, making noise, or failing to circulate water, this guide will help you fix the most common issues quickly and affordably.
1. Pump Not Turning On
Why won’t the pump power up?
It’s frustrating when the pump won’t even start. Fortunately, most of the time the cause is something minor.
Direct Answer: A Bestway pool pump won’t turn on due to power issues, tripped breakers, or a blown internal fuse.
What to check:
- Make sure the power outlet is working—try plugging in another device.
- Check the pump’s power cord and plug for damage or wear.
- Inspect your circuit breaker—reset if tripped.
- Some models have a built-in fuse inside the housing—replace if blown.

2. Pump Is Running but Not Circulating Water
Why is water not moving?
Your pump might be humming or making noise but failing to push water through the filter or return jet.
Direct Answer: When a Bestway pump runs without water flow, it’s likely due to clogs, air locks, or incorrect hose setup.
Fixes:
- Ensure the intake and outlet hoses are connected correctly.
- Prime the pump by filling the filter housing and hoses with water.
- Check for blockages in the skimmer, filter cartridge, or pump inlet.

3. Pump Losing Prime or Full of Air
Why does it keep getting airlocked?
Air in the lines prevents water from circulating properly and can cause the pump to overheat or fail prematurely.
Direct Answer: Air leaks at hose connections or low water levels cause the Bestway pump to lose prime and draw in air.
How to fix it:
- Top off pool water to ensure skimmer stays submerged.
- Use Teflon tape on hose fittings to improve seals.
- Inspect hose O-rings or gaskets and replace if worn out.

4. Pump Making Loud or Unusual Noises
Is it supposed to sound like that?
Bestway pumps usually run quietly. A sudden grinding, humming, or rattling sound means something’s wrong inside or around the motor.
Direct Answer: Loud pump noise usually indicates internal debris, loose parts, or worn bearings in the motor assembly.
What you can do:
- Turn off and unplug the pump before opening the housing.
- Clean out leaves or debris from the impeller area.
- If noise persists, replace the motor or consider a new pump unit.

5. Pump Runs Intermittently or Stops Unexpectedly
Why does it shut off on its own?
This issue is often linked to overheating or poor electrical connections.
Direct Answer: A Bestway pump that stops randomly may be overheating, drawing too much current, or have a failing capacitor.
Quick fixes:
- Ensure proper ventilation around the pump—don’t enclose it or cover the housing.
- Clean the filter regularly to reduce motor strain.
- Replace the pump if it continues overheating after troubleshooting.

6. Dirty or Ineffective Filtration
Why is the pool still dirty?
Even if the pump is working, a clogged or worn filter can prevent it from cleaning the pool properly.
Direct Answer: Poor water clarity from a running Bestway pump usually means the cartridge is clogged or too old to be effective.
How to solve it:
- Rinse the filter cartridge every few days with a garden hose.
- Replace filters every 2–4 weeks during heavy use.
- Consider switching to a sand or cartridge filter upgrade for better performance.

7. Leaks Around the Pump Housing or Hose Fittings
Where is the water coming from?
Water dripping from your pump or hoses can lower pool levels and reduce system efficiency.
Direct Answer: Pump leaks come from loose hose clamps, cracked housings, or worn O-rings at the intake and return ports.
How to fix it:
- Tighten all hose clamps with a screwdriver—don’t overtighten plastic fittings.
- Replace O-rings if they look flattened, cracked, or brittle.
- Patch small housing cracks with waterproof epoxy or silicone sealant.

8. Pump Too Weak for Pool Size
Why can’t it keep up?
Some Bestway pumps that come with entry-level pools are underpowered for anything but basic circulation.
Direct Answer: A weak pump won’t clean the water effectively, especially in larger pools with more than 2,500 gallons.
What to do:
- Upgrade to a higher GPH (gallons per hour) pump rated for your pool volume.
- Add a pre-filter or leaf trap to reduce strain on the main filter.
- Increase filtration run time to 12+ hours during peak season.

Helpful Maintenance Tips to Prevent Pump Issues
- Clean the filter cartridge every 2–3 days during summer.
- Keep hoses free of kinks and check for air leaks regularly.
- Don’t run the pump dry—always prime it with water first.
- Store the pump indoors during the off-season to prevent freeze damage.
- Replace filters monthly or as needed for optimal performance.
