IntelliFlo Drive Kit Assembly
The integrated Variable Frequency Drive (VFD) is the central processing unit for the pump. A persistent alarm light indicates that the onboard diagnostics have detected a critical failure in the drive's power stage or internal circuitry, usually requiring a full drive replacement as the internal components are sealed and non-serviceable.

Shaft Seal and Gasket Kit
Mechanical failure of the ceramic shaft seal allows water to leak into the motor or air to be drawn into the pump basket. This leads to a 'Loss of Prime' or 'Dry Fire' condition, which the drive's logic detects as a torque-to-RPM mismatch, triggering the alarm light to prevent thermal damage to the impeller and housing.

Drive Fan Replacement Kit
The drive uses an active cooling fan to dissipate heat from the high-power transistors. If the fan fails due to bearing seizure or debris, the drive will hit its thermal limit during operation, causing the system to throw an alarm light to prevent permanent silicon damage from heat soak.
