Speed Feedback / Tachometer Fault (VS Models)
Symptom
Pahlén pool pump does not respond to automation system commands but runs manually.
Control Interface / Communication Issue
Symptom
Pahlén pool pump emits a burning smell or visible smoke.
Motor or Wiring Overheating
Symptom
Pahlén pool pump is installed with a Pahlén heat exchanger, and flow through the heater is insufficient.
Insufficient Flow Through Heat Exchanger
Symptom
Pahlén pool pump is leaking water between the pump housing and the motor.
Mechanical Shaft Seal Failure
Symptom
Pahlén pool pump is running but is very noisy, with a rattling or cavitation sound and visible air in the pump lid.
Cavitation / Air Ingress on Suction Side
Symptom
Pahlén pool pump is unusually hot to the touch but still running.
Overheating Under Load
Symptom
Pahlén pool pump is very loud with a high-pitched whine, especially on variable-speed models.
Drive/Motor Acoustic Noise
Symptom
Pahlén pool pump lid is difficult to remove or install and may leak after servicing.
Lid Thread / Clamp Binding
Symptom
Pahlén pool pump loses prime overnight and must be manually primed each day.
Suction-Side Air Ingress / Drain-Back
Symptom
Pahlén pool pump makes a loud grinding or screeching noise while running.
Motor Bearing Failure
Symptom
Pahlén pool pump runs but the pressure on the filter gauge is unusually high.
High System Backpressure
Symptom
Pahlén pool pump runs but the pressure on the filter gauge is very low, and suction at the skimmer is weak.
Suction Restriction / Air Leak
Symptom
Pahlén pool pump runs, but there is sand or debris returning to the pool.
Filter Bypass / Internal Filter Fault
Symptom
Pahlén pool pump runs, but there is very low water flow at the pool returns.
Hydraulic Restriction / Low Circulation
Symptom
Pahlén pool pump runs, but water appears cloudy and circulation seems poor over time.
Inadequate Filtration / Undersized Runtime
Symptom
Pahlén pool pump speed or flow changes when other large electrical loads in the house turn on.
Supply Voltage Fluctuation / Drop
Symptom
Pahlén pool pump starts but shuts off after a few minutes, and then restarts after cooling.
Thermal Overload Cycling
Symptom
Pahlén pool pump trips the circuit breaker or RCD/GFCI shortly after starting.
Electrical Short or Ground Fault
Symptom
Pahlén pool pump vibrates excessively and moves on its mounting base.
Imbalance / Misalignment
Symptom
Pahlén pool pump will not start at all, no humming, but power is available at the equipment pad.
No-Start Electrical Fault
Symptom
Water is leaking from the clear lid area of the Pahlén pool pump.
