Advertisements
E01
Pump will not start, display shows E01 immediately after power-on
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 external controller (e.g. pool automation system)
Communication Error (RS‑485 / External Control Interface)
E10
Pump display shows E10 and 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
Pump display shows E12 and buttons on the control panel do not respond correctly
Keypad / User Interface Error
E13
Pump shows E13 and cannot be controlled by built‑in timer or schedules
Real‑Time Clock / Internal Timer Error
E14
Pump display shows E14 and unit runs only at a fixed speed or not at all
Parameter / Configuration Error
E15
Pump shows E15 and stops when connected to an external flow or pressure switch
External Safety Interlock Open
E16
Pump display shows E16 and unit will not start after a lightning storm or major surge
Surge / Overvoltage Protection Triggered
E17
Pump intermittently stops with E17 when ambient temperature is very low or very high
Ambient Temperature Sensor Error
E18
Pump shows E18 and cannot reach the set speed, running slower than expected
Speed Limit / Torque Limit Exceeded
E19
Pump display shows E19 and the unit restarts repeatedly without user input
Auto‑Restart / Power Interruption Error
E20
Pump shows E20 and cannot be started from remote input, only from 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 lots of air in the pump basket
Cavitation Due to Suction Restrictions or High Lift
Symptom
Pump is noisy with a rattling or grinding sound from the wet end, but motor seems smooth
Impeller Damage or Debris
Symptom
Pump is very noisy, with a loud grinding or screeching sound from the motor end
Worn or Failed Motor Bearings
Symptom
Pump leaks at the threaded or union connections on 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, 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
Pump will not start at all, no display or indicator lights on DAB pool pump
No Power / Dead Pump
