Understanding the Problem
If your Whirlpool WTW4955HW fills and washes but won't drain or spin, the machine leaves clothes soaked and the cycle won't finish. Most top-load Whirlpool machines either fail to remove water because the drain path is blocked or the component that removes water or enables spinning has failed. The problem can be electrical (lid lock switch, control board), mechanical (drain pump, clutch/gearcase), or simply a clog in the drain hose or pump filter. Start by confirming the symptom: if the washer tries to spin (drum attempts to rotate) but there’s water in the tub, it's usually a drainage problem (pump or hose). If the washer does not attempt to spin at all, or the lid lock doesn’t engage, then the lid lock assembly or the control that senses it could be at fault. Proper diagnosis avoids replacing parts unnecessarily and gets your washer back to reliable service faster.
Common Symptoms
Washer completes agitation but clothes stay wet; water remains in tub after drain step; loud grinding or humming during attempted drain; washer won't enter spin and lid lock doesn't click; error codes or blinking lights during cycles.
Common Causes
- Clogged drain hose or pump filter (debris, lint, socks)
- Failed or obstructed drain pump (electrical failure or jammed impeller)
- Faulty lid lock/switch (won't signal control to allow spin)
- Worn clutch, transmission/gearcase problem (won't engage spin)
- Faulty control board or wiring (doesn't command pump or motor)

Helpful Repair Tip
Run a Drain & Spin or Diagnostic cycle with the washer empty. If you hear the pump running and water exits, check the hose and pump for blockages. If you hear no pump sound and the lid is locked, test the lid lock with a multimeter and inspect the drain pump directly for resistance and obstruction.
Frequently Asked Questions
Can I replace the drain pump on a WTW4955HW myself?
Yes — if you are comfortable working safely with appliances. Unplug the washer and turn off the water. Tip the washer back on a protected floor (or remove front panel, depending on model) to access the pump. Remove the hoses and electrical connector, swap the pump, and reassemble. Keep a towel or shallow pan handy for water left in the system. If you’re unsure, take photos during disassembly or call a technician.
How much will it cost to fix a WTW4955HW that won’t drain or spin?
Parts-only: a drain pump or lid lock typically runs $30–$150 depending on OEM vs aftermarket. A gearcase/transmission is much more expensive—often $200–$400. Labor (if using a technician) is commonly $100–$250 depending on local rates and complexity. Start with simple checks (hose, filter, pump) to minimize cost.
