What we repair on the Pentair SuperFlo 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
From Pentair's manual
- Shaft seal 354545S on pumps made before 6/17/19; 17351-0101S after.

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:
