Understanding the Problem
If your Whirlpool top-load washer model WTW4955HW0 fills with water but won't drain or complete the spin cycle, the most common culprits are a failed drain pump, a faulty lid lock (lid switch/locking assembly), a clogged drain hose/filter, or an issue with the main control board or wiring. The washer may attempt the drain cycle, hum, click, or display error codes and then either stop or stay filled with water. Because the washer will not advance to spin when it senses the lid isn't locked or when water remains in the tub, diagnosing this problem requires checking both mechanical and electrical items. Start with the simplest items: inspect the drain hose and pump filter for blockages, listen for the drain pump running during a drain cycle, and confirm the lid lock engages. If the pump doesn't run when it should, or if the lock doesn't secure, those components are the most likely parts to replace.
Common Symptoms
Washer fills but does not drain, stays full of water, will not advance to spin, makes humming or clicking noises during drain, displays error codes, or shows a locked/unlocked lid error.
Common Causes
- Clogged or kinked drain hose or pump filter preventing water exit
- Failed or jammed drain pump (impeller seized or motor failed)
- Faulty lid lock (lid switch/locking assembly) preventing the washer from advancing to spin
- Control board or wiring fault not sending power to drain pump or lid lock

Helpful Repair Tip
Run the washer's diagnostic mode (see manual) and listen during the drain step — if you hear the pump motor running or humming, the pump may be jammed or weak; if there's silence and no locking sound, test the lid lock for continuity with a multimeter.
Frequently Asked Questions
Can I replace the drain pump myself on a WTW4955HW0?
Yes — replacing the drain pump is a common DIY repair if you have basic tools. Always unplug the washer and turn off the water before starting. Access is typically through the rear panel or by tipping the washer back (support safely). Remove the drain hose, disconnect the electrical plug and clamp(s), and swap the pump. After replacement, test the washer on a drain/spin cycle to confirm the repair.
How much will it cost to fix a WTW4955HW0 that won't drain or spin?
Parts costs vary: a drain pump typically ranges $40–$120, a lid lock assembly $30–$90, and a control board can be $150–$350 or more. Labor at a service call commonly adds $100–$250 depending on your area. If the issue is a clogged hose or simple jam, you may be able to fix it yourself at little or no cost.
