What we repair on the Hayward MaxFlo VS 500
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 Hayward's manual
- Shaft seal SPX2700SA, or SPX2700SAV (Viton).
- Power end SPX2303Z1VSPE.
