Understanding the Problem
If your Kenmore SW3949238 fills but won’t spin or won’t drain, the machine will typically sit with water in the tub or fail to agitate/complete a cycle. This problem is commonly caused by a failed lid switch or door lock, a clogged or failed drain pump, a broken drive coupling/belt, or an electrical/control fault. Mechanical issues (like a seized pump or damaged motor coupling) and simple obstructions (pays coins, lint or fabric stuck in pump) both produce very similar symptoms, so a quick targeted diagnosis prevents unnecessary part replacement. Begin diagnosis by confirming whether the washer attempts to drain (you can hear the pump run or hum), whether the lid/door lock engages, and whether the motor runs during spin. Testing the lid switch and pump for continuity with a multimeter and visually checking the drain hose and pump inlet for clogs often identifies the cause. If electrical components test good, inspect mechanical drive components (belt, coupling, clutch/transmission) for wear or breakage — many top-load Kenmore models use a coupling between the motor and transmission that can fail under heavy loads.
Common Symptoms
Washer fills but does not drain; washer won't enter spin cycle; motor hums but tub doesn't spin; visible water remains after cycle; error codes or blinking lights related to drainage or lid lock.
Common Causes
- Failed lid switch or door lock assembly (machine thinks lid is open)
- Clogged or failed drain pump (obstruction or burned motor)
- Broken drive belt or motor coupling (motor runs but tub doesn't turn)
- Faulty control board/timer or wiring problem preventing spin/drain command
- Blocked/ kinked drain hose or clogged pump filter/trap

Helpful Repair Tip
Start with the simplest checks: run a drain/spin cycle and listen—if you hear a humming pump but no water movement, remove the pump inlet and check for a trapped sock/coin; if nothing is heard and the motor doesn't run, test the lid switch for continuity with a multimeter.
Frequently Asked Questions
How do I test the lid switch to see if it’s the problem?
Unplug the washer, access the lid switch (usually under the top or behind the control panel), and remove the switch connector. Use a multimeter set to continuity or ohms: operate the lid latch while probing the switch terminals—an intact switch will show continuity when the lid is closed/latched and open when released. If there’s no continuity when latched, the switch is bad and should be replaced.
Can I replace the drain pump or coupling myself, and how much will it cost?
Yes — many DIYers can replace a drain pump or motor coupling with basic tools and a parts diagram. Parts cost typically: drain pump $25–$80, motor coupling $10–$40, lid switch $15–$50. Expect 30–90 minutes for a pump or coupling job if you’re comfortable removing the washer cabinet. If the transmission or control board is needed, labor and parts costs rise significantly; consider a professional for those repairs.
