Symptom
Pump emits a burning smell and the motor casing is extremely hot to the touch
Severe Motor Overheating / Insulation Breakdown
Symptom
Pump hums but does not start, then trips the breaker after a few seconds
Locked Rotor / Failed Start Circuit
Symptom
Pump is unusually quiet and cool but there is no water flow (motor may not actually be running)
Control Logic / Relay Failure
Symptom
Pump is very noisy, with a loud grinding or screeching sound from the motor end
Motor Bearing Failure
Symptom
Pump loses prime after a few minutes of operation, basket slowly empties and pump sucks air
Suction Air Leak / Inadequate Net Positive Suction Head
Symptom
Pump makes a rattling or clattering noise from the wet end during operation
Impeller Damage or Loose Components
Symptom
Pump motor runs but the impeller does not turn, no water movement
Shaft Coupling / Impeller Drive Failure
Symptom
Pump runs but filter pressure is higher than normal and return jets are weak
High System Backpressure / Filter Restriction
Symptom
Pump runs but flow is weak and filter pressure is lower than normal
Reduced Hydraulic Performance / Partially Blocked Impeller
Symptom
Pump runs but makes a cavitation noise (gravelly, crackling sound) and flow is unstable
Cavitation Due to Inadequate Suction Conditions
Symptom
Pump runs but overheats and shuts off after 10–20 minutes, then restarts after cooling
Thermal Overload Cycling
Symptom
Pump runs but there is a constant stream of air bubbles from the pool return jets
Air Ingress on Suction Side
Symptom
Pump runs but there is no water flow, pump basket does not fill with water
Loss of Prime / Air Ingress on Suction Side
Symptom
Pump runs but water appears cloudy and filtration seems ineffective despite normal pressure
Insufficient Circulation Time or Low Flow Rate
Symptom
Pump speed fluctuates up and down without user input on a variable-speed Espa pump
Unstable Control Input / Sensor Interference
Symptom
Pump starts normally but stops when the pool cleaner line is opened
Excessive Suction Load / Flow Restriction
Symptom
Pump trips the circuit breaker or RCD immediately when switched on
Electrical Short or Earth Leakage
Symptom
Pump vibrates excessively and moves on its base during operation
Imbalance or Poor Mounting
Symptom
Pump will not restart automatically after a power outage, requires manual reset
Auto-Restart / Control Logic Configuration
Symptom
Pump will not start at all, no humming, no display, Espa pool pump appears completely dead
No Power to Pump / Open Circuit
Symptom
Water leaking between the motor and the pump housing under the Espa pump
Mechanical Seal Failure
Symptom
Water leaking from the clear pump lid area when the pump is running
Lid Seal Failure / Cracked Lid
Symptom
Water leaking from the drain plugs at the bottom of the Espa pump housing
Drain Plug Seal Failure
