Hayward PowerFlo Pool Pumps Error Codes
Complete list of fault codes and troubleshooting guides. Use the search below to find your specific error.
Advertisements
GF
GFCI outlet or breaker trips immediately when the Hayward PowerFlo pump is turned on; some smart GFCI devices may show GF or a ground fault indicator.
Ground Fault / Leakage to Ground
LO
Digital control (aftermarket timer/controller) shows LO and pump will not start or shuts off shortly after starting.
Low Voltage Protection Trip
OL
External digital controller or smart relay shows OL and shuts the Hayward PowerFlo pump off after a short run.
Overload / Overcurrent Protection Trip
PF
Aftermarket digital pump controller displays PF and the Hayward PowerFlo pump will not run.
Pump Fault / Motor Protection Trip
Symptom
Hayward PowerFlo pump basket fills with air bubbles while running; return jets show constant bubbles.
Suction Air Leak / Cavitation
Symptom
Hayward PowerFlo pump cycles on and off by itself every few minutes.
Thermal Overload Cycling
Symptom
Hayward PowerFlo pump emits a burning smell or visible smoke from the motor area.
Motor Overheating / Electrical Failure
Symptom
Hayward PowerFlo pump housing is cracked and leaking water from the side or bottom.
Pump Housing Structural Failure
Symptom
Hayward PowerFlo pump hums but will not start; motor housing may get warm and then shut off.
Failed Start Capacitor or Stalled Rotor
Symptom
Hayward PowerFlo pump impeller is difficult to remove or appears melted/deformed.
Impeller Heat Damage / Deformation
Symptom
Hayward PowerFlo pump is leaking water from where the motor meets the pump housing.
Failed Mechanical Shaft Seal
Symptom
Hayward PowerFlo pump is significantly louder after a recent impeller or seal replacement.
Improper Reassembly / Misalignment
Symptom
Hayward PowerFlo pump is unusually loud with a high-pitched whine, but still moves water.
Early Bearing Wear / Electrical Noise
Symptom
Hayward PowerFlo pump lid is difficult to remove or install; threads bind or squeak.
Lid Thread Wear / O-ring Swell
Symptom
Hayward PowerFlo pump loses prime intermittently; it starts with good flow but then the basket slowly empties and the pump sucks air.
Intermittent Suction Air Leak
Symptom
Hayward PowerFlo pump makes a loud grinding or screeching noise while running.
Worn Motor Bearings
Symptom
Hayward PowerFlo pump makes a rattling or clattering noise, especially at startup or when air is present.
Cavitation / Air in Pump
Symptom
Hayward PowerFlo pump motor fan at the rear does not spin even though the shaft turns inside.
Broken Cooling Fan
Symptom
Hayward PowerFlo pump motor housing shows visible rust and corrosion on the exterior.
External Corrosion / Environmental Damage
Symptom
Hayward PowerFlo pump motor runs backwards (for certain replacement motors) causing poor or no flow.
Incorrect Motor Rotation (for reversible motors)
Symptom
Hayward PowerFlo pump motor shaft is rusted where it meets the seal plate; repeated seal failures occur.
Corroded Motor Shaft at Seal Surface
Symptom
Hayward PowerFlo pump produces a loud thump or bang at startup or shutdown.
Hydraulic Shock / Water Hammer
Symptom
Hayward PowerFlo pump runs but flow is weak; return jets have low pressure compared to normal.
Restricted Flow / Partial Blockage
Symptom
Hayward PowerFlo pump runs but the pressure gauge on the filter is very high and flow at the returns is reduced.
High System Head / Filter Restriction
Symptom
Hayward PowerFlo pump runs but the pressure gauge on the filter is very low and there is little suction at the skimmer.
Suction Restriction / Air Leak
Symptom
Hayward PowerFlo pump runs but there is no water flow; pump basket does not fill with water.
Loss of Prime / Air Ingress on Suction Side
Symptom
Hayward PowerFlo pump runs but water appears cloudy or dirty despite circulation.
Inadequate Filtration / Low Turnover
Symptom
Hayward PowerFlo pump runs very hot to the touch and may shut off after a period, then restart later.
Motor Overheating / Thermal Overload Trip
Symptom
Hayward PowerFlo pump trips the circuit breaker shortly after starting.
Overcurrent / Short Circuit
Symptom
Hayward PowerFlo pump vibrates excessively and may move on its base during operation.
Imbalance or Mounting Vibration
Symptom
Hayward PowerFlo pump will not hold prime after being off overnight; must be manually primed each day.
Slow Air Ingress / Backflow Loss
Symptom
Hayward PowerFlo pump will not turn on at all; no humming or sound when switched on.
No Power / Open Circuit
Symptom
Water is leaking from the clear lid area on the Hayward PowerFlo pump during operation.
Lid Seal Leak
Symptom
Water is leaking from the drain plug area at the bottom of the Hayward PowerFlo pump housing.
Drain Plug Seal Failure
