Non‑Volatile Memory / Parameter Error
Symptom
Pump emits a burning smell and may smoke from the motor area
Overheated Motor Windings
Symptom
Pump housing is cracked and leaking water
Freeze Damage or Mechanical Stress Crack
Symptom
Pump hums but will not start (older single‑speed or two‑speed Sta‑Rite Max‑E‑Pro / Dyna‑Glas models)
Failed Start Capacitor or Stuck Start Switch
Symptom
Pump is noisy with a rattling or grinding sound from the wet end
Damaged Impeller or Loose Diffuser
Symptom
Pump is unusually loud only at high speed on variable‑speed model
Hydraulic Noise / Resonance at High RPM
Symptom
Pump is very noisy with a loud grinding or screeching sound
Worn Motor Bearings
Symptom
Pump leaks at the drain plugs on the bottom of the housing
Damaged or Missing Drain Plug O‑Rings
Symptom
Pump leaks water at the clamp band or housing seam
Failed Housing O‑Ring / Seal Plate Gasket
Symptom
Pump leaks water between the motor and pump housing
Failed Mechanical Shaft Seal
Symptom
Pump makes a loud cavitation or gravelly sound and the pump lid is full of air
Cavitation Due to Suction Restriction or High Lift
Symptom
Pump motor runs but impeller does not turn (no water movement)
Broken Shaft or Stripped Impeller Hub
Symptom
Pump runs but has very low flow and weak return jets
Hydraulic Restriction / Suction or Discharge Blockage
Symptom
Pump runs but pressure gauge on filter reads zero and there is no circulation
Air‑Bound System / No Discharge Flow
Symptom
Pump runs but spa jets are weak when in spa mode
Insufficient Flow in Spa Circuit
Symptom
Pump runs but there are lots of bubbles at the pool returns
Suction Side Air Leak
Symptom
Pump runs for a few minutes then trips the thermal overload and shuts off
Overheating Motor
Symptom
Pump trips the circuit breaker immediately when turned on
Electrical Short Circuit or Ground Fault
Symptom
Pump turns on and off repeatedly (short cycling)
Intermittent Power or Thermal Overload Cycling
Symptom
Pump vibrates excessively and moves on the pad during operation
Imbalance or Mounting Issue
Symptom
Pump will not prime; pump pot does not fill with water
Loss of Prime / Suction Air Leak
Symptom
Pump will not start after winter; motor is seized
Corroded or Frozen Motor / Impeller
Symptom
Variable‑speed pump display is blank but power is present at the breaker
No Low‑Voltage Power to User Interface
Symptom
Variable‑speed pump runs only at one speed and ignores programmed schedules
Control Logic / Programming Fault
