UNI087 Generic Washing Machine Drain Pump DC31-30008D Universal Washer Water Pump Part

UNI087 is a generic universal drain pump for washing machines, also listed under the number DC31-30008D. It's the part that pumps used water out of the tub and into your laundry trough or standpipe. Because it's a universal design rather than a direct brand replacement, the best check is a side by side comparison of the mounting points, outlet spigot and electrical terminals with your old pump.

Washing machine not draining? When the pump is to blame

Between the wash and rinse, and again before the spin, the drain pump has to clear the water from the drum. When the impeller jams or the motor winding fails, water stays behind. You may find the machine full at the end of a cycle, hear a hum or buzz with no water moving, or see a drain error on the display. Before buying a pump, check the pump filter and drain hose for blockages such as coins, hair pins or lint, as these cause the same symptoms.

Swapping the drain pump

Unplug the washer and turn off both taps. Drain any trapped water through the filter or drain hose into a tray before opening up the pump area, and keep towels on hand. Take photos of the wiring and hose clamps, transfer them to the new pump in the same positions, and tighten the clamps properly. Run a rinse and spin to check it empties and doesn't leak.

Questions about this part

Is this a direct replacement for my brand's pump?

No, it's a generic universal pump. It suits machines whose pump matches its mounting, outlet and terminal layout. Compare it closely with your old pump, and if they don't line up, a brand specific pump is the better choice.
