Step by step
-
1 Confirm the pump is dead
Clean the filter first, half of "dead pump" calls are a clogged trap. A pump that hums with a clear filter, grinds, or is silent during drain is genuinely done.
-
2 Get access
Front loaders. Remove the lower front panel (a few screws under the lip). Top loaders. Tilt the machine back or remove the rear/front panel per your model, the pump sits at the tub’s lowest point.
-
3 Photograph, then disconnect
Photo the hose routing and wiring plug. Release the spring clamps with pliers, wiggle the hoses off into your pan, and unplug the electrical connector.
-
4 Swap the pump
Most pumps mount with 2 to 3 screws or a twist lock bayonet. Transfer to the new pump, reconnect hoses (clamps seated past the bead) and the plug.
-
5 Leak test before closing
Run a small fill and a drain cycle with the panel still off and watch every connection, then button it up.

If a new pump still won’t run, the control board isn’t sending it power, that diagnosis needs a meter and a wiring diagram, which is a fast pro visit instead of a parts guessing game. If you'd rather skip it entirely, find a washer repair pro near you
