E01
Pump will not start; display shows E01 immediately after power-up.
Overcurrent / Locked Rotor Protection
E02
Pump stops during operation and displays E02; may restart after a cool-down period.
Overtemperature / Thermal Protection Trip
E03
Pump display shows E03 and the motor will not run or stops shortly after starting.
Undervoltage / Low Line Voltage Fault
E04
Pump display shows E04 and the motor does not start or shuts down quickly.
Overvoltage / High Line Voltage Fault
E05
Pump display shows E05; motor will not start or runs erratically.
Internal Drive Fault / Electronics Failure
E06
Pump display shows E06; motor may start and then shut down or fail to start at all.
Phase / Motor Feedback Error (Internal Motor Sensor Fault)
E07
Pump display shows E07; pump may not respond to keypad commands or external control.
Communication / Keypad Interface Error
E08
Pump display shows E08; pump may not start or may shut down unexpectedly.
Ground Fault / Leakage Current Detected
E09
Pump display shows E09; pump may not start or may run only at limited speeds.
Parameter / Configuration Error
Symptom
Display is blank or very dim, but pump still runs at a fixed speed.
Display Backlight / LCD Failure
Symptom
Display is on but keypad buttons do not respond or respond intermittently.
Keypad / Membrane Failure
Symptom
Pump emits a burning smell or visible smoke while running.
Motor Overheating / Electrical Failure
Symptom
Pump housing or volute is cracked and leaking water.
Cracked Pump Housing / Volute
Symptom
Pump hums but will not start; may trip breaker after a few seconds (especially on single-speed SuperFlo models).
Failed Start Capacitor or Seized Motor (Non‑VS Models)
Symptom
Pump is cavitating: loud, crackling or gravel-like noise from the pump, with fluctuating pressure and flow.
Hydraulic Cavitation
Symptom
Pump is leaking water between the motor and the pump housing.
Failed Mechanical Shaft Seal
Symptom
Pump is running but is extremely noisy, with a high-pitched whine or grinding sound.
Worn Motor Bearings
Symptom
Pump is unusually hot to the touch on the motor housing, even though it is running.
Elevated Operating Temperature
Symptom
Pump is very loud with a roaring or whooshing sound and large amounts of air are visible in the pump basket.
Severe Air Ingestion on Suction Side
Symptom
Pump leaks from the drain plug(s) at the bottom of the pump housing.
Leaking Drain Plug O-Rings
Symptom
Pump leaks water from the clear lid area when running.
Leaking Pump Lid Seal
Symptom
Pump loses prime after a few minutes of running; pump basket runs dry and water stops flowing.
Suction Air Leak / Inability to Maintain Prime
Symptom
Pump makes a loud rattling or grinding noise and flow is reduced.
Debris in Impeller / Damaged Impeller
Symptom
Pump makes intermittent clicking or knocking sounds during operation.
Intermittent Mechanical Interference
Symptom
Pump motor runs briefly and then shuts off, repeating this cycle.
Thermal Overload Cycling
Symptom
Pump runs but filter pressure is very low and returns are weak.
Suction Restriction / Air Ingress
Symptom
Pump runs but GFCI breaker or outlet trips frequently.
Ground Fault / Leakage Current
Symptom
Pump runs but has very low flow or no water movement at the pool returns.
Loss of Prime / Suction Restriction
Symptom
Pump runs but there is a persistent small leak at the union connections near the pump.
Leaking Pump Unions
Symptom
Pump runs but trips the breaker after a short time.
Overcurrent / Electrical Overload
Symptom
Pump runs but water appears cloudy or circulation seems inadequate despite normal pressure.
Insufficient Circulation / Underspeed Operation
Symptom
Pump runs but water pressure at the filter gauge is very high compared to normal.
Discharge Restriction / Dirty Filter
Symptom
Pump speed fluctuates up and down without changes to settings (VS models).
Unstable Speed Control / Drive Regulation Issue
Symptom
Pump vibrates excessively and may move on the pad during operation.
Excessive Vibration / Misalignment
Symptom
Pump will not restart after a power outage until breaker is cycled or settings are re-entered.
Improper Power Recovery / Auto-Restart Configuration
Symptom
Pump will not start at all; no display, no lights, and no motor noise.
No Power to Pump / Dead Pump
Symptom
Pump will not turn off or on according to the programmed schedule (VS models).
Programming / Timer Configuration Issue
