E16
Display shows E16 and pump will not start; may be accompanied by a beeping alarm.
Lockout / Child Lock or Safety Interlock Active
E17
Display shows E17 and pump stops when connected to certain external devices (e.g., Flowclear chlorinator or heater).
External Accessory Communication Error
E18
Display shows E18 and pump cannot detect water flow through integrated Flowclear saltwater system (if combined unit).
Integrated Salt System Flow Error
Symptom
Pump buttons are unresponsive or require very hard pressing to work.
Keypad / Button Wear
Symptom
Pump display is dim, flickering, or unreadable, but the pump still runs.
Display / LCD Failure
Symptom
Pump frequently turns off by itself after running for a short time, then restarts later.
Thermal Overload Cycling
Symptom
Pump hums loudly but the impeller does not spin; may trip breaker after a few seconds.
Locked Rotor / Seized Motor
Symptom
Pump is running but there are large amounts of air bubbles visible at the pool return.
Suction Air Leak
Symptom
Pump is very noisy during operation, with grinding or screeching sounds.
Worn Motor Bearings / Mechanical Wear
Symptom
Pump motor housing is excessively hot to the touch during normal operation.
Overheating Motor
Symptom
Pump runs but makes a rattling noise, especially when flow is restricted.
Cavitation / Air in Pump
Symptom
Pump runs but the pool water remains cloudy or dirty despite circulation.
Ineffective Filtration / Bypass
Symptom
Pump runs but there is a strong burning or electrical smell.
Overheating Electrical Components
Symptom
Pump runs but there is very weak water flow back into the pool.
Restricted Circulation / Low Flow
Symptom
Pump runs but water leaks from the multiport valve or top of the Flowclear sand filter.
Valve Seal / Spider Gasket Failure
Symptom
Pump timer does not start or stop the pump at the programmed times, but manual operation works.
Timer Programming / Logic Fault
Symptom
Pump trips the GFCI/RCD or household breaker as soon as it is turned on.
Short Circuit / Ground Fault
Symptom
Pump vibrates excessively and may move on the ground during operation.
Imbalance / Mounting Vibration
Symptom
Pump will not hold prime; it loses water and fills with air shortly after starting.
Loss of Prime / Air Ingress
Symptom
Pump will not start at all; no lights or display on the Flowclear control panel.
No Power / Dead Unit
Symptom
Sand or debris is returning to the pool from the Flowclear sand filter return line.
Filter Internal Failure
Symptom
Water is leaking from hose connections at the pump or filter.
Hose Connection Leak
Symptom
Water is leaking from the clear pump lid area.
Lid Seal / O-Ring Failure
Symptom
Water is leaking from under the pump housing during operation.
Pump Housing / Mechanical Seal Leak
