Pentair Pentair IntelliFlo VSF Variable Speed Pool Pump DRIVE BOARD FAIL Error Fix: Drive Board Failure

Error code DRIVE BOARD FAIL on the Pentair Pentair IntelliFlo VSF Variable Speed Pool Pump means: Drive Board Failure. The variable speed drive (VFD) circuit board has failed. The pump may be completely non-responsive, or it may display persistent error codes that do not clear with power cycling. Often caused by lightning strikes or power surges — the drive board is the most surge-sensitive component on the pump. Moisture intrusion into the drive compartment (from rain, sprinklers, or condensation) can also cause board failure. The drive board must be replaced as a unit (not field-repairable). Typical cost is $300-600 for the board plus installation. Consider installing a dedicated surge protector on the pump circuit to prevent recurrence.
