Signs an LG water pump has failed

A water pump moves water through or out of the appliance when the control asks for it. When it fails, water stays where it shouldn't, the appliance may stop with an error code, or the pump hums, buzzes or rattles without shifting anything. Leaks around the pump body or its connections are another clue. Before replacing it, rule out the simple causes, such as a blocked filter or inlet, a kinked hose or a loose plug, because these often mimic a dead pump.

Replacing the water pump

Switch off at the wall and unplug, turn off the water supply, and have towels and a shallow tray ready, because some water is usually trapped in the pump and hoses. Photograph the wiring and hose layout first. Move across any clips or seals the new pump doesn't include, then check for leaks on a short cycle before closing up the panels.

Questions about this part

How can I test the old pump before buying a new one?

With the power off, a multimeter across the pump terminals will show whether the winding is open circuit. Also check the impeller turns freely if you can reach it, as debris can stop a healthy pump. A repairer can confirm the fault if you're unsure.
