# LG dishwasher pump replacement

### The kitchen side of a job that happens under the sink

This is the one dishwasher repair that needs the machine out of its opening, and the room decides how straightforward that is. New flooring laid up against a machine that was already there, a countertop the mounting brackets screw into, and a shutoff valve nobody has turned in nine years are the three things that turn a contained afternoon into a longer one. Clear the cabinet beside it and the floor in front of it before we arrive. A pump that is genuinely failing announces itself first, with a grinding or a whine on the drain that gets shorter each week until the water simply stays.

What this involves

Diagnosed before it is quoted — most suspected pumps are blockages

The machine comes out and goes on its back

A stocked part on LG, which keeps the number down

Prove the pump

Measured, and listened to. A blockage and a failure sound different and cost differently.

Drain the machine fully first

A dishwasher tipped with water in it empties into the kitchen.

Replace the pump and its seal

The seal is not optional and it is the reason a second leak follows a first repair.

Check what killed it

Glass in the sump, a missing filter, or a machine that has been running blocked for months.

Test drain and fill under load

Full cycle, not a rinse.

### How do you know it is the pump and not a blockage?

The path is checked from the sump to the disposal first, and the pump itself is tested for continuity and for whether it turns at all. A pump does not get condemned merely because the water is still there.

### Will my floor be damaged?

It should not be. We put boards down and lift rather than drag, and if the flooring was laid around the machine we will tell you what is possible before we start rather than while it is halfway out.
