Pump starts then stops after a few seconds without any error code on basic models

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

Seized or stiff motor bearings, Overloaded impeller due to blockage, Incorrect voltage causing high current, Faulty thermal overload in motor

Safety first: Disconnect power before inspecting the motor or impeller.

Steps to check:

Check shaft rotation: With power off, rotate the motor shaft by hand. If stiff or rough, bearings may be failing.
Inspect impeller: Open the wet end and remove any debris from the impeller.
Verify supply voltage: Have an electrician confirm that the supply matches the motor rating.
If overload keeps tripping: Replace the motor or have it professionally rebuilt, including a new overload device.
