What we repair on the Pentair IntelliFloXF VS
A permanent-magnet motor run by an electronic drive — no start capacitor to replace. When one fails we read the drive's own fault before touching a part.
- Drive or keypad showing a fault, or the display dark — diagnosed against the manufacturer's fault list
- Not answering the automation or app — communication wiring and settings
- Speeds and schedules set wrong — reprogrammed for this pool, so it runs slow and quiet most of the day
- Leaking at the shaft seal (water under the motor) — a new mechanical seal before the bearings rust
- Air in the basket and losing prime — lid o-ring, basket, drain plugs, suction-side unions
- Loud grinding or screeching — worn motor bearings
- Low flow — impeller clogged or worn, diffuser gasket, basket
- Cracked strainer housing, lid or basket

If it is time to replace it
Repair first when it makes sense. When the housing is cracked, the motor is failing on an old single-speed, or the parts are no longer made, these are the pumps to look at:
Pentair IntelliFlo3 VSF
Pentair's current variable speed and flow pump: it holds a set flow rather than just a speed, and runs from the Pentair Pool app over Wi-Fi.
