Undervoltage / Incorrect Supply Voltage Protection
E02
Pump attempts to start, hums briefly, then stops and shows E02.
Overcurrent / Motor Overload Protection
E03
Pump stops during operation and displays E03 after running for several minutes.
Motor Overtemperature Protection
E04
Display shows E04 and pump will not start, sometimes after a power surge or lightning storm.
Internal Electronics / Inverter Fault
E05
Pump display shows E05 and motor does not run, sometimes accompanied by a clicking sound.
Phase Loss / Phase Imbalance (for three‑phase DAB pool pumps with inverter)
E06
Pump stops and shows E06, often when starting or changing speed.
Motor Stall / Rotor Lock Detection
E07
Display shows E07 and pump speed cannot be adjusted, or pump will not start.
Speed Sensor / Feedback Error (for variable‑speed DAB pool pumps)
E08
Pump display shows E08 and unit shuts down shortly after start.
Ground Fault / Earth Leakage Detection
E09
Pump shows E09 and cannot communicate with an external controller (e.g., pool automation system).
Communication Error (RS‑485 / External Control Interface)
E10
Pump display shows E10 and the unit will not start, often after being stored or unused for a long period.
Dry‑Run / No‑Water Protection
E11
Pump runs briefly then stops with E11, especially at higher speeds.
Overpressure / High Discharge Pressure Protection
E12
The pump display shows E12, and buttons on the control panel do not respond correctly.
Keypad / User Interface Error
E13
The pump shows E13 and cannot be controlled by the built-in timer or schedules.
Real-Time Clock / Internal Timer Error
E14
The pump display shows E14, and the unit runs only at a fixed speed or not at all.
Parameter / Configuration Error
E15
The pump shows E15 and stops when connected to an external flow or pressure switch.
External Safety Interlock Open
E16
The pump display shows E16, and the unit will not start after a lightning storm or major surge.
Surge / Overvoltage Protection Triggered
E17
The pump intermittently stops with E17 when the ambient temperature is very low or very high.
Ambient Temperature Sensor Error
E18
The pump shows E18 and cannot reach the set speed, running slower than expected.
Speed Limit / Torque Limit Exceeded
E19
The pump display shows E19, and the unit restarts repeatedly without user input.
Auto-Restart / Power Interruption Error
E20
The pump shows E20 and cannot be started from a remote input, only from the local panel.
Remote Start/Stop Input Error
Symptom
Pump cannot be primed after winterization or long shutdown, even after multiple attempts.
Persistent Air Lock / Suction Line Issue
Symptom
Pump cannot reach higher speeds or flow rates on a variable-speed DAB model, even when commanded.
Speed Limitation / Derating
Symptom
Pump emits a burning smell or visible smoke from the motor housing.
Motor Winding Overheating / Burnout
Symptom
Pump hums but does not start, then may trip the breaker or overload.
Failed Start Capacitor (Single-Phase Models)
Symptom
Pump is cavitating, making a loud hissing or gravelly sound, with a lot of air in the pump basket.
Cavitation Due to Suction Restrictions or High Lift
Symptom
Pump is noisy with a rattling or grinding sound coming from the wet end, but the motor seems smooth.
Impeller Damage or Debris
Symptom
Pump is very noisy, with a loud grinding or screeching sound coming from the motor end.
Worn or Failed Motor Bearings
Symptom
Pump leaks at the threaded or union connections on the suction or discharge ports.
Union / Pipe Joint Leakage
Symptom
Pump leaks water between the pump housing and motor, often forming a rust trail on the motor.
Failed Mechanical Seal
Symptom
Pump leaks water from around the clear lid on top of the DAB pump basket.
Lid O-Ring Seal Failure
Symptom
Pump motor runs hot to the touch, even though it continues to operate.
Overheating Motor (Non-Tripping)
Symptom
Pump runs but causes excessive air bubbles in the pool returns.
Suction Side Air Ingress
Symptom
Pump runs but filter pressure is higher than normal, and flow at returns is weak.
System Backpressure / Restriction
Symptom
Pump runs but flow is weak; pressure at the filter gauge is lower than normal.
Reduced Flow / Hydraulic Underperformance
Symptom
Pump runs but makes a high-pitched whine from the inverter/control area (variable-speed models).
Inverter Switching Noise / Possible Inverter Stress
Symptom
Pump runs but there is no water flow; the pump basket does not fill with water.
Loss of Prime / Air-Locked Pump
Symptom
Pump starts then stops after a few seconds without any error code on basic models.
Thermal Overload Trip (Manual or Auto-Reset)
Symptom
Pump trips the circuit breaker or RCD immediately when turned on.
Electrical Short or Ground Fault
Symptom
Pump vibrates excessively, causing pipes to shake and making a droning noise.
Mechanical Vibration / Misalignment
Symptom
The pump will not start at all; there is no display or indicator lights on the DAB pool pump.
No Power / Dead Pump
