This Part Fixes These Problems

Dishwasher Not Draining

Water remains pooled in the bottom of the tub after the wash cycle completes — the most common symptom of a failed drain pump motor.

Grinding or Squealing Noise

Loud grinding, squeaking, or humming during the drain phase indicates the impeller or motor bearings have failed inside the pump assembly.

Drain Error Code

Samsung dishwasher displays a 5C, 5E, or OC error code signaling a drain failure — often caused by a seized or burned-out drain pump motor.

Water Leaking Under Dishwasher

A cracked pump housing or deteriorated rubber gasket seal allows water to leak beneath the appliance during or after the drain cycle.

Cycle Won't Complete

The dishwasher stalls mid-cycle and does not advance to the dry phase because the drain pump cannot clear the tub water as required by the control board.

💡 Pro Tip: Is Your Drain Pump the Problem?

Your part is likely the culprit if you notice any of the following:

⚠️ Standing water or puddles left in the dishwasher tub after the cycle ends

⚠️ Squeaking, grinding, or loud humming noise during the drain phase

⚠️ Wash cycle fails to complete or dishwasher displays a drain error code

⚠️ Visible water leaking from beneath the dishwasher near the pump area

🔍 Diagnostic tip: Set your multimeter to the continuity setting and probe the pump motor terminals. No continuity = failed motor; replace the pump. Drain pumps are not repairable — replacement is the only fix. Also inspect the drain hose and filter basket for blockages before ordering; a clogged filter can mimic a bad pump.

Questions & Answers

Will this DD81-02635A pump fit my Samsung DW80R2031US/AC dishwasher?
Answered by Support Team  ·  Mar 15, 2024
Yes. The DW80R2031US/AC (and /AC-00) is one of the core compatible models for this pump assembly. The part uses the same Hanyu B20-3A01 motor platform and identical mounting dimensions, so it installs directly with no modifications. Always verify your full model and serial number on the door jamb label before ordering.
My dishwasher shows a 5C error code. Is the drain pump definitely the problem?
Answered by Support Team  ·  Nov 20, 2023
A 5C (or 5E) error code indicates a drain failure, and a faulty drain pump is the top cause — but not the only one. Before replacing the pump, check that the filter basket and drain hose are clear of debris, and that the drain hose is not kinked or installed too high. If those are fine, test the pump motor with a multimeter for continuity. No continuity confirms the pump has failed and needs replacement.
Does this replacement pump come with the rubber gasket/seal?
Answered by Support Team  ·  Jan 8, 2025
Our aftermarket DD81-02635A pump assembly includes the impeller, motor, and ABS housing. We recommend inspecting the rubber gasket on your old pump before removal — if it is still pliable and undamaged, it can be reused on the new pump. If it is cracked or compressed, source a replacement seal (part DD81-02221A) at the same time to prevent leaks after installation.
How long does it take to replace the drain pump on a Samsung dishwasher?
Answered by Support Team  ·  Jul 22, 2024
For a first-time DIYer, plan for 30–45 minutes. The job involves removing the lower access panel, disconnecting one wiring harness, releasing the drain hose clamp, and twisting or unscrewing the pump from the sump — no special tools beyond a Phillips screwdriver and pliers. Experienced technicians can typically complete the swap in under 20 minutes.
Is this pump compatible with the newer DW80CG4021SRAA and DW80CG4051SRAA models?
Answered by Support Team  ·  Feb 10, 2026
Yes. Both the DW80CG4021SRAA and DW80CG4051SRAA are confirmed compatible models for the DD81-02635A drain pump assembly. Samsung carried the same pump design (Hanyu B20-3A01, 120V/0.7A/60Hz) forward into the CG-series lineup. If your dishwasher model begins with DW80CG40, this pump is the correct replacement.
