Understanding the Problem
If your Samsung WM3670HVA is leaving water in the tub or taking too long to drain, the problem is usually in the drain path: the drain pump, hoses, or a clogged filter/trap. You may notice standing water after the cycle, error codes, gurgling sounds, or the washer getting stuck on Drain/Spin. Drain problems can be caused by mechanical failure (a burned-out or jammed pump motor), blockages (coins, lint, or fabric caught in the pump or hoses), or electronic/control issues preventing the pump from running. Confirming the cause requires a few simple checks: listen for pump noise during a drain cycle, remove standing water and inspect the pump inlet, and check the drain hose and household drain for clogs.
Common Symptoms
Washer stops with water in the tub, slow draining, gurgling or humming noises during drain, error codes related to drainage, clothes very wet after spin.
Common Causes
- Clogged drain hose or household drain (kink, lint or blockage)
- Foreign object jammed in the drain pump impeller (coins, buttons, small clothing items)
- Failed drain pump motor or burned windings
- Clogged pump filter / coin trap (if equipped)
- Control board, pump relay, or wiring failure preventing the pump from getting power

Helpful Repair Tip
Run a Drain/Spin cycle and listen—if you hear the pump humming but no water moves, the impeller is likely jammed or broken; if it's silent, test the pump for continuity with a multimeter or look for a blown fuse/board relay.
Frequently Asked Questions
How do I safely check the pump and clear a clog?
Unplug the washer and turn off the water. If your model has a pump access panel or filter, place towels and a shallow pan to catch water, open the access and manually remove debris from the filter/pump inlet. If no access panel, you may need to remove the lower front panel to reach the pump. Inspect the pump impeller for broken fins or trapped items. Reassemble and run a drain/spin cycle to test. If the pump motor hums but the impeller won’t turn, replace the pump.
How much does it cost to replace the drain pump and how long does it take?
Parts for a Samsung drain pump typically run $50–$150 depending on source and exact part number; labor (if you hire a technician) is usually another $75–$200. If you do the repair yourself, replacement commonly takes 30–60 minutes for most DIYers familiar with appliance disassembly—longer if you need to remove the front or rear panel to access the pump. Always confirm part compatibility with your washer's model and serial tag before ordering.
