Aquaflow Overheating or Loose Electrical Connection

Pump runs intermittently, starting and stopping on its own without error code

This repair may involve working with high voltage components or water connections. Always unplug the appliance before removing any panels.

If you are not confident in your ability to perform this repair safely, we strongly recommend contacting a professional technician.

Possible Causes

Thermal overload cycling, Loose line connection at terminal block, Failing motor, Undersized wiring causing voltage drop

Safety first: Turn off power before opening any covers.

Check motor temperature: After shutdown, carefully feel the Aquaflow motor housing. Very hot surfaces indicate overheating.
Inspect connections: Tighten all terminal screws in the pump's wiring compartment and at the breaker panel (electrician recommended).
Verify wire size: Ensure the supply cable gauge matches Aquaflow's installation requirements for the run length.

If the motor continues to cycle on thermal overload, it may be nearing end of life and should be replaced.
