Advertisements
E01
The pump will not start; the display shows E01 immediately after pressing START.
Supply Undervoltage Protection
E02
The pump stops shortly after starting; the display shows E02 and will not restart until power is cycled.
Overcurrent / Motor Overload Trip
E03
The pump display shows E03 and the motor does not run, sometimes accompanied by a humming noise.
Phase Loss / Phase Imbalance (for three‑phase Saci pumps)
E04
The pump stops during operation and shows E04; the housing feels very hot to the touch.
Motor Overtemperature Protection
E05
Variable-speed Saci pump shows E05 and will not ramp up to set speed.
Speed Sensor / Feedback Error
E06
Pump display shows E06 and the motor does not start, sometimes after a power surge or lightning storm.
Internal Drive / PCB Fault
E07
Pump shows E07 and stops, often when starting at high speed or under heavy load.
Overload / Torque Limit Exceeded
E08
Pump display shows E08 and the motor will not start, often after incorrect wiring changes.
Incorrect Supply Frequency / Configuration Error
E09
Pump intermittently stops and shows E09, especially in damp environments.
Ground Fault / Earth Leakage Detected
E10
Pump display shows E10 and ignores external control signals from the automation system.
Communication / External Control Error
E11
Pump shows E11 and cannot be programmed; buttons may be unresponsive.
Keypad / User Interface Fault
E12
Pump display shows E12 and the speed fluctuates unexpectedly.
Internal Sensor Calibration Error
E13
Pump shows E13 and will not start after being idle for a long period.
Stalled Rotor / Locked Rotor Detection
E14
Pump display shows E14 and the unit runs only at minimum speed or shuts down.
Internal Temperature Sensor Fault
E15
Pump displays E15 and fails to detect priming, shutting down after a short run.
Priming Failure / Dry-Run Protection
Symptom
Display on Saci variable-speed pump is blank, but the motor hums or runs.
Display Power / Interface Failure
Symptom
Pump emits a burning smell during operation.
Overheating Windings or Electrical Components
Symptom
Pump housing or nearby pipes vibrate excessively during operation.
Excessive Vibration / Misalignment
Symptom
Pump intermittently stops when it rains or when the equipment area is wet.
Moisture Ingress / Inadequate Weather Protection
Symptom
Pump is humming but will not start, then trips the breaker or thermal overload.
Failed Start Capacitor / Stalled Motor
Symptom
Pump is noisy with a rattling or rumbling sound that changes with flow rate.
Cavitation / Hydraulic Noise
Symptom
Pump is very noisy, with a loud grinding or screeching sound from the motor end.
Worn Motor Bearings
Symptom
Pump makes a loud clicking or knocking noise once per revolution.
Impeller or Fan Obstruction
Symptom
Pump motor is extremely hot to the touch, but continues running.
Overheating Without Trip
Symptom
Pump runs but causes frequent nuisance tripping of the RCD/GFCI.
Earth Leakage / Insulation Degradation
Symptom
Pump runs but there is no water flow or only a weak trickle from the pool returns.
Loss of Prime / Suction Restriction
Symptom
Pump runs but water leaks steadily from the joint between the pump housing and motor.
Failed Mechanical Seal
Symptom
Pump runs, but filter pressure is much higher than normal and flow is reduced.
Discharge Restriction / Dirty Filter
Symptom
Pump runs, but pool circulation is weak and filter pressure is lower than normal.
Suction-Side Air Leak / Partial Blockage
Symptom
Pump speed on variable-speed Saci model does not change even when different speeds are selected.
Speed Control / Drive Output Fault
Symptom
Pump starts and stops repeatedly every few seconds (short cycling).
Control Instability / Protection Cycling
Symptom
Pump trips the circuit breaker immediately when switched on.
Electrical Short Circuit
Symptom
Pump will not start at scheduled times, but runs when started manually.
Timer / Programming Issue
Symptom
Pump will not turn off from the keypad; only by cutting power at the breaker.
Stuck Relay / Control Fault
Symptom
Water leaking from the clear pump lid area when the pump is running.
Damaged Pump Lid O-Ring / Cracked Lid
Symptom
Water leaking from the drain plugs at the bottom of the Saci pump housing.
