Pentair Pool Pump Error Code 06: How to Fix It

Q: What does error code 06 mean on a Pentair pool pump?

Error code 06 on a Pentair pool pump means the Variable Frequency Drive (VFD) has detected an over-current condition. This means the motor is drawing more electrical current than the drive's safe operating threshold, which can be caused by a clogged impeller, seized motor bearings, closed valves, wiring faults, or a failing VFD drive board.

Q: Can I reset Pentair error code 06 myself?

Yes, you can attempt a reset by turning off the pump at the breaker, waiting 5 minutes for the VFD to fully discharge, and then restoring power. However, if the error returns immediately after restart, simply resetting it will not fix the underlying problem. You need to diagnose and correct the root cause — such as a blockage, wiring fault, or motor issue — before the error will stay cleared.

Q: Will a clogged impeller cause Pentair error code 06?

Yes, a clogged or partially blocked impeller is one of the most common causes of error code 06. When debris such as leaves, twigs, or dirt jams the impeller, the motor has to work much harder to maintain flow, which causes it to draw excess current and triggers the VFD over-current fault. Cleaning the strainer basket and impeller is always one of the first steps to try.

Q: How much does it cost to fix Pentair error code 06?

If the fix is as simple as clearing a clogged strainer basket or opening a closed valve, the cost is essentially zero. A service call from a pool technician typically runs $100–$200 for diagnosis and minor repairs. If the motor needs replacement, expect $300–$700 for parts and labor depending on the pump model. A full VFD drive board replacement on a variable speed pump like the IntelliFlo can cost $400–$900 or more including labor.

Q: Can error code 06 damage my Pentair pool pump permanently?

If error code 06 is ignored and the pump is repeatedly run in an over-current condition, yes, it can cause permanent damage to the motor windings and VFD drive board. However, the VFD's built-in over-current protection is designed to shut the pump down before catastrophic damage occurs. Address the fault promptly rather than continuing to force restarts without fixing the root cause.

Abstract

Error code 06 on a Pentair pool pump indicates a Variable Frequency Drive (VFD) over current condition, meaning the pump's motor or drive is drawing more electrical current than it should. This is often triggered by a mechanical obstruction, a failing motor, or an electrical wiring issue that forces the VFD to work harder than its rated capacity. Left unaddressed, this fault can damage the VFD board or motor windings, so it's important to diagnose and resolve the root cause promptly.
