AquaFlo Pumps are known for their reliability and performance, but like any mechanical equipment, they may encounter occasional issues. Understanding common problems and knowing how to troubleshoot them can help you maintain your pump effectively. Here are some typical issues with AquaFlo Pumps and how to address them:

1. Pump Not Starting

  • Check Power Supply: Ensure that the pump is receiving power by verifying the electrical connections and checking the circuit breaker or fuse box.
  • Inspect Timer Settings: If your pump is controlled by a timer, verify that the timer settings are correct and that the pump is scheduled to run at the desired times.
  • Check for Blockages: Inspect the pump and filter for any debris or blockages that may be preventing the impeller from turning.

2. Low Flow Rate or Weak Pumping

  • Clean Filter: A clogged or dirty filter can restrict water flow. Remove and clean the filter according to manufacturer’s instructions.
  • Check for Air Leaks: Air leaks in the suction line or around fittings can cause a loss of prime and reduce flow rate. Inspect all connections and seals for leaks and tighten or replace as necessary.
  • Verify Pump Speed: If your pump has variable speed settings, ensure that it is set to an appropriate speed for the desired flow rate.

3. Noisy Operation

  • Check for Debris: Foreign objects or debris stuck in the impeller or pump housing can cause noise. Disconnect power and inspect the pump for any obstructions, removing them carefully.
  • Lubricate Bearings: Over time, bearings may require lubrication. Refer to the manufacturer’s instructions for recommended lubricants and procedures.
  • Inspect Motor Mounting: Ensure that the pump motor is securely mounted and aligned properly with the pump housing to prevent vibration and noise.

4. Leaks

  • Inspect Seals and O-Rings: Over time, seals and O-rings can wear out or become damaged, leading to leaks. Inspect these components regularly and replace them if necessary.
  • Tighten Connections: Check all plumbing connections and fittings for tightness. Sometimes, leaks can occur due to loose connections that simply need to be tightened.

5. Pump Overheating

  • Check Ventilation: Ensure that the pump motor and housing have adequate ventilation to prevent overheating. Clear any obstructions around the pump that may restrict airflow.
  • Reduce Load: If the pump is running at high speeds continuously, consider reducing the speed or operating time to alleviate overheating.
  • Inspect Motor Capacitor: A faulty or failing capacitor can cause the motor to overheat. Consult a professional technician to test and replace the capacitor if necessary.

6. Erratic Operation or Error Codes

  • Refer to Manual: Consult the manufacturer’s manual for troubleshooting steps specific to any error codes displayed on the pump control panel.
  • Reset System: Sometimes, power cycling the pump (turning it off and on) can resolve temporary glitches in operation.
  • Check Control Settings: Verify that all control settings, including timer settings and speed adjustments, are correctly configured according to the pump’s specifications.


Regular maintenance and timely troubleshooting of AquaFlo Pumps can help prevent and resolve common issues, ensuring continuous and efficient operation of your pool or spa system. If you encounter persistent problems that you are unable to resolve, contact a qualified pool technician or the manufacturer’s customer support for further assistance. Taking proactive steps to address issues promptly will extend the lifespan of your AquaFlo Pump and enhance your overall pool or spa experience.
