Whirlpool WTW4950 Washer: Problems, Codes & Fixes

Which models this covers#

Built from 2016 to 2023, the WTW4950 shares one platform and parts catalog:

• WTW4950HW
• WTW4950HW2
• WTW4950XW

A same-prefix model not listed here uses the same tub, impeller, and controls, so the guidance applies.

Specifications#

Common problems for this model#

1. Suspension rods snap — 22%. The tub drops and bangs, and the machine walks across the floor on spin.
2. Lid-lock assembly fails — 18%. The lock light flashes and the washer will not start.
3. Impeller hub strips — 14%. The impeller spins but clothes do not move through the water.
4. Drain-pump bearing noise — 12%. A loud whine on drain that ends in pump failure.
5. Shift actuator fails — 10%. The machine fills and agitates but will not shift into spin.

Why it walks across the floor#

The suspension rods at number one are the fault to understand, because they present as violent shaking rather than an obvious broken part. The WTW4950 hangs its tub on four spring-loaded rods that damp motion; when one rod's internal spring snaps, the tub swings freely at high spin and the machine bangs and walks. Replace all four rods at once — the set is W10780048 — since a single new rod against three tired ones just fails again. Before assuming rods, though, confirm the washer is level with a bubble level on the lid and that any shipping bolts were removed, because an unlevel machine mimics the same symptom.

Error codes#

For any other code, unplug the unit or flip the breaker for 60 seconds, then restore power.

Recall status#

There are no active recalls on the Whirlpool WTW4950 series as of 2026-05-28. Check your model number at the Consumer Product Safety Commission — cpsc.gov — periodically, since recalls can be issued at any time.

Repair or replace?#

The usual line applies: under 10 years old and a fix under 50% of a new washer favors repair; past 10 years, weigh the total history against 40% of replacement cost. The suspension rods, lid lock, and shift actuator are all common, cost-effective repairs on this platform.

Before you call#

Put a bubble level on the lid and adjust the leveling legs until it centers, and confirm the shipping bolts are gone if the washer was recently installed. For a lid-lock complaint, unplug for 60 seconds and restore power; if the lock light still flashes with the lid shut, the lock likely needs replacing rather than a reset. Do not wrap large items around the impeller — load them loosely so clothes have room to circulate, and never overload.

Common questions#

What is the difference between an agitator and an impeller? The WTW4950 uses a low-profile impeller disc that creates currents to move clothes, rather than a tall center-post agitator. It frees up space and is gentler on fabrics, but it needs loose loading to clean well.

Why does it walk across the floor on spin? Almost always a broken suspension rod. The four rods damp tub motion, and when one spring snaps the tub swings freely; replace all four as a set (W10780048).

How do I reset the WTW4950? Unplug for 60 seconds, restore power, then lift and lower the lid six times within about a half second each to reset the motor control board.
