Keypad / User Interface Fault
E15
Harris pump shows E15 and runs only at a default speed or not at all
Program Memory / Parameter Corruption
Symptom
Pump display is blank but motor hums or runs
Display / User Interface Power Loss
Symptom
Pump does not start on schedule; timer or programmed speeds are not being followed
Timer / Scheduling Malfunction
Symptom
Pump emits a burning smell or visible smoke from the motor area
Motor Overheating / Electrical Burn
Symptom
Pump housing or plumbing vibrates and makes a water hammer or banging noise when the pump stops
Hydraulic Shock / Water Hammer
Symptom
Pump is humming but will not start; may trip breaker after a few seconds
Failed Start Capacitor / Locked Rotor
Symptom
Pump is leaking water between the motor and the pump housing
Shaft Seal Failure
Symptom
Pump is very noisy with a loud grinding or screeching sound while running
Motor Bearing Failure
Symptom
Pump makes a loud cavitation or rattling noise and the pump pot is not completely full of water
Cavitation Due to Restricted Suction or High Lift
Symptom
Pump makes a rattling or clicking noise from the wet end, especially at startup
Loose Impeller or Worn Diffuser
Symptom
Pump motor is extremely hot to the touch and may shut off intermittently
Motor Overheating
Symptom
Pump motor runs but makes a low-frequency humming or buzzing and seems to lack power
Capacitor Degradation / Voltage Imbalance
Symptom
Pump runs but filter pressure is much lower than normal and suction at skimmer is weak
Low Suction / Air Ingress
Symptom
Pump runs but pressure at the filter gauge is much higher than normal
High System Backpressure
Symptom
Pump runs but there is no water flow or very weak flow at the pool returns
Hydraulic Flow Restriction / Loss of Prime
Symptom
Pump runs but water appears cloudy and circulation seems poor despite normal pressure
Inadequate Circulation / Underspeed Operation
Symptom
Pump trips the circuit breaker immediately or within a few seconds of starting
Electrical Short / Overcurrent
Symptom
Pump turns on and off rapidly (short cycling) without user input
Intermittent Power / Control Instability
Symptom
Pump vibrates excessively and may move slightly on the pad during operation
Imbalance / Mounting Vibration
Symptom
Pump will not prime; pump pot does not fill with water and pump makes a gurgling sound
Suction-Side Air Leak / Priming Failure
Symptom
Pump will not turn off using the keypad; only turns off at the breaker
Stuck Relay / Control Logic Fault
Symptom
Water leaking from around the clear pump lid on top of the Harris pump
Lid Seal / O-Ring Leak
Symptom
Water leaking from the drain plugs at the bottom of the Harris pump housing
Drain Plug Seal Leak
