Dishwasher Not Draining? Drain Pump DD31-00016A – Fix Standing Water Fast

If your Samsung dishwasher finishes a cycle but leaves standing water at the bottom, the drain pump is the most likely cause. In most Samsung DW80 series dishwashers, the drain pump is responsible for expelling all wastewater at the end of each cycle — when it fails, water pools at the bottom of the tub, cycles run incomplete, or the unit throws a drain error code. ⚡ Common failure point in Samsung DW80J, DW80M, DW80R, and DW80B series dishwashers. Part DD31-00016A is the genuine OEM replacement that restores full drainage and normal cycle completion.

❓ Is This the Right Part?

This is the correct fix if ALL of the following are true:

• ✔ Dishwasher powers on and control panel functions normally
• ✔ Wash cycle runs but water remains in the tub at the end
• ✔ Drain hose and garbage disposal connection confirmed clear and unkinked
• ✔ Filter and sump area cleaned — no blockage found
• ✔ ONLY problem is standing water, incomplete drain, or drain error code

🔧 Common Symptoms

• Standing water at the bottom of the dishwasher tub after cycle ends
• Dishwasher displays drain error code (e.g. 5C, 5E, OC, OE)
• Cycle runs but never fully completes — stops mid-drain
• Gurgling or humming noise during drain phase with no water movement
• Dishes come out wet or dirty due to incomplete cycle

✔ If these symptoms match, the drain pump is the most likely failed component in the system.

✔ In most cases, replacing the drain pump restores normal drainage and full cycle operation immediately.
