High Pressure / High Head Condition
LO
Davey pool pump display alternates between speed setting and LO, and the pump either runs at reduced output or stops.
Low Flow / Low Pressure Warning
OC
Davey variable speed pool pump shows OC and stops immediately after attempting to start.
Overcurrent Trip (Drive Protection)
PF
Davey pool pump controller shows PF and the pump will not start.
Power Failure / Brownout Detected
Symptom
Pump body or unions leak at the threaded connections.
Union Seal / Threaded Joint Leak
Symptom
Pump causes radio or Wi-Fi interference when running.
Electromagnetic Interference from Motor/Drive
Symptom
Pump emits a burning smell during operation.
Overheating Electrical Components
Symptom
Pump hums but does not start; may trip the breaker after a few seconds.
Failed Start Capacitor / Locked Rotor
Symptom
Pump is unusually loud with a cavitation-like crackling noise, especially at high speed.
Cavitation Due to High Suction Lift or Restriction
Symptom
Pump is very noisy with a loud grinding or screeching sound while running.
Worn or Failed Motor Bearings
Symptom
Pump leaks water between the pump housing and the motor.
Failed Mechanical Shaft Seal
Symptom
Pump makes a rattling or clicking noise, especially at start-up.
Loose Impeller or Worn Diffuser Components
Symptom
Pump performance has gradually decreased over months; longer run times needed to keep pool clean.
Hydraulic Efficiency Loss
Symptom
Pump runs but air bubbles are constantly visible in the pool return jets.
Persistent Air Ingress on Suction Side
Symptom
Pump runs but filter pressure is very high and return flow is poor.
Filter Blockage / High Head Condition
Symptom
Pump runs but flow is weak and filter pressure is low.
Suction Restriction / Air Ingress
Symptom
Pump runs but there is no water circulation back to the pool (no visible flow at return jets).
Loss of Prime / Airlocked Pump
Symptom
Pump runs very hot to the touch and may shut down after some time.
Overheating Motor
Symptom
Pump starts and stops repeatedly within short intervals (short cycling).
Control Logic / Protection Cycling
Symptom
Pump trips the circuit breaker or RCD immediately when switched on.
Electrical Short / Earth Leakage
Symptom
Pump vibrates excessively and may move on the pad during operation.
Imbalance / Mounting Issue
Symptom
Pump will not restart automatically after a power outage, even though it was running before.
Auto-Restart / Memory Setting Issue
Symptom
Pump will not start at all; no lights or display on the Davey controller.
No Power / Control Failure
Symptom
Variable speed Davey pump does not respond to speed changes or programming.
Control Interface / Programming Fault
Symptom
Water leaks from around the clear pump lid when the pump is running.
Lid Seal Failure / Debris on Seal
