Introduction

Use this guide to replace the drain pump motor in your LG WM3050CW Washing Machine.

The drain pump motor is part of the pump assembly. It drains the tub and expels the wastewater out of the washer. If your washer isn't draining, you may need to replace this motor.

The metal ring holding the rubber boot can be difficult to reinstall. You can buy this tool to make the reinstallation easier, or ask additional people to help.

Step 1

Before you begin your repair, perform the following:
Turn off the main water supply
Unplug your washer
Disconnect all water connections at the rear of your washer

Step 2

Use a Phillips driver to remove the two bottom 16.5 mm-long screws securing the top panel brackets.

Step 3

Slide the top panel 1-2 inches towards the rear of the device to disconnect its clips.

Step 4

Tilt the top panel upward to completely disconnect it from the chassis.
Remove the top panel.

Step 5

Pull the detergent drawer away from the chassis as far as it will go.

Step 6

Press down on the "Push" button to disengage the clips securing the detergent drawer.
Pull the drawer out of its slot on the chassis and remove it.

Step 7

Disconnect the three harness connectors for the control panel.
Always grip cables by their connectors and not the wires themselves.

Step 8

Use a Phillips driver to remove the 16.4 mm-long screw securing the control panel.

Step 9

Use a Phillips driver to remove the two 26.3 mm‑long screws securing the detergent dispenser.

Step 10

Insert a flathead screwdriver between the chassis and the top left corner of the control panel.
Twist the screwdriver to release the clips securing the control panel.
Repeat this procedure for the remaining clips along the control panel.

Step 11

Lift the control panel upward to completely separate it from the chassis.
Pull the control panel away from the chassis, making sure to thread the cables through its slot in the chassis.
Remove the control panel.

Step 13

Use needle nose pliers to grip the spring end of the metal ring at the bottom of the rubber boot.
Pull the ring away from the chassis to separate it from the boot.

Step 14

Use your hand to completely pull the ring off the boot.
During reassembly, perform the following:
Insert one end of the ring into its groove along the boot's perimeter.
Use pliers to slowly stretch the ring around the boot's perimeter until it's completely nested in its groove.
This procedure will take significant force.

Step 15

Use your fingers to pull the boot off its lip on the front panel.

Step 16

Work your fingers around the boot until its completely separated from the panel.

Step 17

Open the filter panel at the bottom left of the front panel.
Twist the filter panel upward to unclip it from the front panel.

Step 18

Use a Phillips driver to remove the two 12.8 mm‑long screws securing the filter trim.

Step 19

Pull the filter trim straight off the front panel to remove it.

Step 20

Use a Phillips driver to remove the 12.8 mm-long screw securing the lower front panel.

Step 21

Use a Phillips driver to remove the two 16 mm‑long screws securing the door latch.

Step 22

Pull the door latch through its slot in the chassis and let it hang on its wire.

Step 23

Hold the front panel against the chassis while performing this step to prevent it from falling.
Use a Phillips driver, or a 7 mm nut driver, to remove the six 15 mm‑long screws securing the front panel.

Step 24

Lift the front panel upward to separate it from its clips on the bottom of the chassis.
Pull the front panel away from the chassis to completely separate the front panel.

Step 26

Twist the pump filter handle counterclockwise to separate it from the pump assembly.
Pull the filter straight out of the pump block assembly to remove it.

Step 27

Push the drain hose through its hole in the chassis until it's completely inside the device.

Step 28

Use diagonal cutters, or scissors, to remove the cable ties securing the plastic wrap to the pump assembly cables.

Step 29

Repeat the previous step for any cable ties bundling the pump assembly cables.

Step 30

Fold the plastic wrap away from the cables, enough to expose the connectors.
During reassembly, replace the cable ties to ensure a water-tight fit for the plastic wrap.

Step 31

Disconnect the connector attached to the pump cable.
Always grip cables by their connectors and not the wires themselves.

Step 32

Use slip joint pliers to pinch the pump discharge hose clamp and slide it up the hose away from the pump assembly.

Step 33

Use slip joint pliers to rotate the pump discharge hose back and forth around its connection and loosen it.
Pull the pump discharge hose straight off its connection on the assembly.

Step 34

Repeat the last two steps for the tub-to-pump hose.

Step 35

Use a 3/8 inch socket wrench to remove the three 46.1 mm-long screws securing the pump assembly.

Step 36

Lift the pump assembly out of its location in the frame to remove it.

Step 37

Use a Phillips driver to remove the three 14.4 mm‑long screws securing the pump body.

Step 38

Pull the pump body straight off the pump to remove it.

Step 39

To avoid confusion, note the locations of the motor screws.
Use a Phillips driver to remove the three 21.6 mm‑long screws securing the pump motor.

Step 40

Pull the pump motor straight off the pump to remove it.

Step 41

To prevent confusion, label each spade connector with its corresponding cable color.
Disconnect the two spade connectors attached to the pump motor.
Always grip cables by their connectors and not the wires themselves.

Step 42

Pull the plastic pump housing off of the motor and remove it.
Set this housing aside, as you will need to reinstall it on the new pump motor.
