What we repair on the Hayward EcoStar / EcoStar SVRS
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
- Error names: PFC-Hi (supply over 280 V — not a fault in the pump), Prime Failed (no prime in 15 minutes), AC Mains Low, Drive is Overheated, Stall Error, SVRS Tripped.
- Replacement drive SPX3400DR (SVRS: SPX3400DRVR) — fit the display that comes with the new drive.

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:
Hayward TriStar VS 900 / 950
The keypad TriStar VS: the 950 replaces most high-performance pumps up to 3 HP, the 900 pumps up to 2 HP max-rated. Omni versions add Hayward's hub and touch pad.
1.85 THP (900) · 2.7 THP (950) · 115/230V — no conversion needed
