Fix a dishwasher that will not drain with a direct fit DD31-00005A drain pump motor assembly. This is the pump mounted under the dishwasher tub bottom that pushes waste water out through the drain hose at the end of every cycle. If your Samsung dishwasher will not drain, leaves standing water, makes a loud buzzing but no flow, or throws a drain error code, this pump is the first part to check before calling a repair tech.

Built to match the original Samsung specification including the sealed motor body, single outlet port, and two wire harness. Swapping a weak or seized pump stops dirty water from backing up into the sump and protects the float switch from false trips.

Symptoms This Fixes

  • Dishwasher will not drain after cycle

  • Standing water left at the bottom

  • Pump buzzes or hums but no water moves

  • Drain error code on the front panel

  • Water leaks from the bottom because the sump backs up

Why Replace Instead of Living With It

A failing pump lets food debris sit in the sump, grows odor, and can trip the flood float. A seized motor draws high current and may take the control board relay with it. Replacing this 120V 45W pump takes about 30 to 45 minutes. Shut off the breaker, pull the lower access panel, photograph the wire positions, release the hose clamp, unplug the harness, twist the pump lock ring, and seat the new unit in reverse order. Always test with a short rinse cycle before closing the panel.
