XPARTCO DD31-00016A Dishwasher Drain Pump Motor
The XPARTCO DD31-00016A is an aftermarket replacement BLDC (brushless DC) drain pump motor for Samsung dishwashers. This motor removes water from the dishwasher tub during the drain phase of the cycle — an impeller mechanism pumps water out through the drain hose, running during the draining phase to ensure a constant, steady flow and help prevent clogs.
Weighs approximately 0.50 lbs, with package dimensions of 4.02" x 3.50" x 3.54". Compatible with 120V and 230V systems. Common causes of failure include worn motor bearings, electrical failure, or debris obstructing the impeller. Symptoms of a failing drain pump motor include water not draining from the tub, standing water left after a cycle, unusual noise during the drain phase, or intermittent draining problems that don't happen every cycle. It directly replaces AP5917178, 113121, 4000925, EAP9606350, PS9606350, ASM773863, PD00036475, and 045900194701.

Installation Notes
Frequently Asked Questions
My dishwasher isn't draining. Is this the part I need?
Yes, this is the most direct symptom of a failed drain pump motor. Since this motor is what removes water from the tub during the drain phase, a worn or failed motor can leave standing water behind or prevent the cycle from completing properly.
My dishwasher's drainage problem only happens sometimes. Could this still be the motor?
Yes, this is possible. One customer replaced this exact motor to address an intermittent draining issue, noting it was somewhat of a guess since the problem didn't occur every cycle. Intermittent symptoms can still point to a motor that's beginning to fail rather than one that's failed completely, though it's worth noting the customer wasn't fully certain the replacement resolved their specific issue.
What's the trickiest part of installing this motor?
Removing the old motor requires holding a release tab open while twisting the motor counterclockwise at the same time — a two-handed maneuver that one customer specifically called out as the biggest challenge of the whole repair. Taking it slowly and keeping steady pressure on the tab through the full twist makes this easier.
Is this an OEM or aftermarket part?
This is an aftermarket replacement part built to OEM-equivalent quality standards. It is not a genuine Samsung OEM part, but is manufactured to match the motor design, impeller mechanism, and voltage compatibility of the original DD31-00016A drain pump motor used in compatible Samsung dishwashers.
