Pentair IntelliFlo Error Code — Fix Guide

What Does This Error Mean?

Pentair IntelliFlo pumps display fault codes on their keypad screen. Drive overcurrent (caused by debris in the impeller or a seized bearing) and overtemperature (caused by poor ventilation) are the most common. Turn the pump off, clear any obstruction, and restart.

Affected Models

Pentair IntelliFlo VSF
Pentair IntelliFlo3 VSF
Pentair IntelliFlo Variable Speed 011028
Pentair SuperFlo VS

Common Causes

Drive overcurrent — impeller jammed or bearing seized
Overtemperature — ambient temperature too high or ventilation blocked
Dry run protection — pump ran without water
Communication error — automation system wiring fault
EEPROM error — internal memory corruption

How to Fix It

Read and note the exact error code shown on the display.

The IntelliFlo displays errors as text (Priming Failure, Drive Overtemp, Overcurrent) or as fault numbers. Note the exact message before clearing it.
For drive overcurrent: check the impeller for debris.

Turn off power at the breaker. Close the suction valve and remove the pump basket lid. Look into the impeller port for leaves, gravel, or debris and remove it.
For overtemperature: improve ventilation around the pump.

The IntelliFlo drive generates heat — it needs airflow around the motor and control head. Remove any debris, leaves, or covers blocking the top of the pump. Do not install the pump in a sealed enclosure.
For dry run protection: restore water flow before restarting.

Dry run protection shuts the pump off when it detects no water is flowing. Check pool water level, open any closed valves, and confirm the pump basket is full of water before restarting.
Power off the pump for 5 minutes and restart.

For most fault codes, powering off for 5 minutes allows the drive to cool and the controller to reset. Restart at a low speed (1500 RPM) rather than full speed immediately.

When to Call a Professional

A drive overcurrent that returns immediately after clearing all obstructions indicates a failed bearing or drive board. Contact Pentair support for authorized repair.

Frequently Asked Questions

What does Drive Overcurrent mean on a Pentair IntelliFlo?

Drive Overcurrent means the motor is drawing more current than the drive can safely provide — usually because the impeller is jammed with debris or a bearing is seizing. Clear the impeller and restart. If the fault returns immediately, the bearing or drive needs replacement.

How do I clear a fault on a Pentair IntelliFlo pump?

Turn the pump off using the keypad, wait 5 minutes, and turn it back on. For most faults, you must address the root cause first — clearing a fault without fixing the underlying problem will just cause it to return.
