Worn or Damaged Diffuser
Symptom
Sta-Rite pool pump digital display is blank or very dim, but the motor still runs when controlled by external automation.
Failed Display / User Interface Power
Symptom
Sta-Rite pool pump does not respond to automation commands; runs only from its local controls.
Automation Control Failure
Symptom
Sta-Rite pool pump emits a strong chemical or burning plastic odor from the control housing on variable-speed models.
Overheating Control Board / Component Failure
Symptom
Sta-Rite pool pump housing is cracked or deformed, sometimes leaking or sucking air.
Cracked Pump Volute / Housing
Symptom
Sta-Rite pool pump hums but will not start; motor housing gets warm and trips the breaker or thermal overload.
Failed Start Capacitor or Start Circuit (single-speed/dual-speed models)
Symptom
Sta-Rite pool pump is extremely noisy, with grinding or screeching sounds while running.
Worn Motor Bearings
Symptom
Sta-Rite pool pump is unusually loud with a high-pitched whine, especially at higher speeds on variable-speed models.
Acoustic Resonance / Worn Bearings on VS Motor
Symptom
Sta-Rite pool pump leaks at the clear lid on top of the strainer housing; air bubbles may be visible under the lid.
Leaking Pump Lid O-Ring / Cover Gasket
Symptom
Sta-Rite pool pump leaks at the union connections on the suction or discharge ports.
Leaking Pump Unions / Threaded Fittings
Symptom
Sta-Rite pool pump leaks water between the pump housing and the motor, often forming a puddle under the motor.
Failed Mechanical Shaft Seal
Symptom
Sta-Rite pool pump motor emits a burning smell or visible smoke shortly after starting.
Motor Winding Overheating / Electrical Failure
Symptom
Sta-Rite pool pump motor is very hot to the touch and shuts off after running for a short time, then restarts after cooling.
Thermal Overload Tripping
Symptom
Sta-Rite pool pump motor shaft shows visible rust or pitting near the seal area.
Corroded Motor Shaft at Seal Surface
Symptom
Sta-Rite pool pump on a saltwater pool shows accelerated corrosion on metal parts and frequent seal failures.
Chemical / Saltwater Damage to Pump Components
Symptom
Sta-Rite pool pump runs but has very low flow and the filter pressure gauge reads much higher than normal.
Discharge Restriction / Dirty Filter
Symptom
Sta-Rite pool pump runs but has very low flow and the filter pressure gauge reads much lower than normal.
Suction Restriction or Air Leak / Loss of Prime
Symptom
Sta-Rite pool pump runs but makes a loud rattling or clattering noise from the wet end.
Cavitation or Debris in Impeller
Symptom
Sta-Rite pool pump runs but there is no water movement in the pool; returns are not flowing.
Pump Not Moving Water / Lost Prime or Disconnected Impeller
Symptom
Sta-Rite pool pump runs but water flow surges up and down; pressure gauge fluctuates.
Intermittent Air Ingestion / Suction Leak
Symptom
Sta-Rite pool pump timer or built-in schedule does not start the pump at the programmed times.
Internal Timer / Programming Fault
Symptom
Sta-Rite pool pump trips the breaker immediately or within a few seconds of starting.
Short Circuit or Ground Fault in Motor
Symptom
Sta-Rite pool pump vibrates excessively and may move on the equipment pad during operation.
Pump Vibration / Misalignment
Symptom
Sta-Rite pool pump will not hold prime; loses water in the strainer basket shortly after shutoff.
Suction-Side Air Leak / Check Valve Failure
Symptom
Sta-Rite pool pump will not turn on at all; no sound from motor and no lights on digital display (if equipped).
No Power / Electrical Supply Failure
