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.
LG WM6700HBA notes & error codes
On LG direct drive machines there is no standalone hall sensor, it is integrated into the stator, so an LE fault means diagnosing the stator assembly rather than ordering a separate sensor.
| Code | What it means |
|---|---|
| OE | Drain error |
| LE | Motor locked / rotor position fault |
| IE | Water inlet fault |
| UE | Unbalanced load |
| dE | Door lock fault |
Full details for this machine, common problems, causes, and costs, are in the LG WM6700HBA repair guide. The general version of these instructions is here.
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
