What we repair on the Hayward TriStar VS 900 / 950
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
- The display says what is wrong in words — e.g. "Pump has stalled", "Drive overload", "DC voltage too low" — and keeps the last 20 errors in an event log.
- Factory password 1234; hold Speed 1 and Speed 4 while powering on to reset it.
- Breaker: 15 A at 230V, 20 A at 115V.
- Shaft seal SPX3200SA, or SPX4000SAV (Viton).
