Symptom
Waterway pool pump display is blank or unreadable, but the motor still runs.
Display / LCD Failure
Symptom
Waterway pool pump emits a high‑pitched whining noise that increases with speed.
Hydraulic Cavitation / Air Entrapment
Symptom
Waterway pool pump has very weak flow and the pressure gauge on the filter is low.
Suction Restriction / Clogged Pump Basket or Skimmer
Symptom
Waterway pool pump hums loudly but the motor shaft does not turn; trips breaker if left powered.
Failed Start Capacitor / Start Circuit
Symptom
Waterway pool pump intermittently shuts off and then restarts on its own without any error display.
Intermittent Power Loss / Thermal Cycling
Symptom
Waterway pool pump is leaking water from the area between the motor and the pump housing.
Failed Mechanical Shaft Seal
Symptom
Waterway pool pump is unusually loud compared to when it was new, even though it still works.
General Wear / Aging Components
Symptom
Waterway pool pump leaks at the threaded suction or discharge fittings on the pump housing.
Fitting / Union Leak at Pump Ports
Symptom
Waterway pool pump leaks from around the clear lid on top of the strainer pot.
Lid Seal Failure / Air and Water Leak at Strainer Cover
Symptom
Waterway pool pump makes a loud grinding or growling noise while running.
Worn Motor Bearings
Symptom
Waterway pool pump makes a loud rattling or clattering noise from the wet end.
Loose or Damaged Impeller / Debris in Impeller
Symptom
Waterway pool pump motor is extremely hot to the touch and may shut off intermittently.
Motor Overheating / Thermal Overload Tripping
Symptom
Waterway pool pump motor runs but emits a burning smell or visible smoke.
Electrical Overheating / Insulation Breakdown
Symptom
Waterway pool pump motor shaft is rusted and difficult to turn by hand.
Corrosion from Prolonged Leakage
Symptom
Waterway pool pump runs but flow is weak and filter pressure is very high.
Discharge Restriction / High System Head
Symptom
Waterway pool pump runs but the clear lid shows a large pocket of air and return jets blow bubbles.
Suction Air Leak / Partial Prime
Symptom
Waterway pool pump runs but there is no water flow; pump basket does not fill with water.
Loss of Prime / Air Leak on Suction Side
Symptom
Waterway pool pump runs but there is visible water spraying from the seam of the pump housing.
Pump Housing O‑Ring Failure / Housing Crack
Symptom
Waterway pool pump runs but water in the pump basket appears to surge or oscillate, causing inconsistent flow.
Flow Instability / Intermittent Suction
Symptom
Waterway pool pump trips the circuit breaker immediately when turned on.
Short Circuit / Ground Fault
Symptom
Waterway pool pump vibrates excessively and may move slightly on the equipment pad.
Imbalance / Mounting Vibration
Symptom
Waterway pool pump will not restart automatically after a power outage; must be started manually each time.
Auto‑Restart / Memory Configuration Issue
Symptom
Waterway pool pump will not start at all; no hum, no sound, and no movement from the motor.
No Power / Open Circuit to Pump
Symptom
Waterway variable‑speed pool pump does not change speed when programmed; always runs at one speed.
Programming / Control Logic Issue
