Whirlpool WTW4950XW1 washer Parts

The Whirlpool WTW4950XW1 washer has a 3.6 cu. ft. capacity. This is the tub volume the washer is designed around; actual usable capacity varies by fabric type, cycle selection, and how freely the load can move for proper wash action. See the owner's manual for loading guidance by cycle.

We recommend loading for movement, not for “full to the top.” A properly loaded top-load washer cleans better and spins out more water.

• Load items loosely and evenly around the washplate
• Keep bulky items (blankets, jackets) to one per load when possible
• Mix large and small items to balance the load
• Avoid packing clothes down; it reduces agitation and rinsing
• Use the correct water temperature and soil level for the load

These are typical examples for a 3.6 cu. ft. top-load washer like the WTW4950XW1.

Overloading is a top cause of poor cleaning, out-of-balance spinning, and extra wear on drive components like the washer drive belt WPW10006384 and suspension. Loading correctly helps the washer drain and spin efficiently and reduces vibration.

On the Whirlpool WTW4950XW1, a lid lock “reset” is usually done by power-cycling the washer and then running the built-in diagnostic sequence to clear a stuck state. If the lid still will not lock or unlock afterward, the lid lock switch may be failing.

• Press Power/Cancel to end the cycle.
• Unplug the washer (or turn off the breaker) for 1 minute.
• Plug back in and wait 30 seconds.
• Open and close the lid firmly.
• Start a Rinse/Spin (or a short cycle) and listen for the lid lock click.

Many Whirlpool top-load models use a dial pattern to enter diagnostics. Use the exact sequence shown in your owner's manual.

Typical dial sequence:

• Start with the washer off (no indicator lights).
• Within about 6 seconds, rotate the cycle selector:
  • 3 clicks right
  • 1 click left
  • 1 click right
• If the console lights begin flashing, you are in diagnostic mode.

These checks isolate whether the problem is the lock, the lid strike alignment, or a control issue:

• Make sure the lid is closing squarely; do not slam it.
• Confirm the washer is level; excessive cabinet twist can prevent the lock from aligning (leveling guidance is in the installation guide).
• Try a different cycle; some cycles lock at different times.
• If you hear no lock attempt (no click), inspect wiring connections to the lock.
• If the lock clicks repeatedly or shows intermittent operation, replace the washer lid lock assembly W10404050.

The lid lock is a safety interlock. If it does not confirm “locked,” the control can stop filling, agitating, spinning, or draining, which can look like a bigger washer failure.

The most common Whirlpool washer problem is a no-start condition where the washer has power (lights on) but will not begin a cycle. On the Whirlpool WTW4950XW1, this is often tied to the lid lock system, control inputs, or a safety condition that prevents the motor from running.

• Confirm the lid is fully closed and nothing is caught between the lid and top panel.
• Unplug the washer for 2 minutes, then plug it back in to reset the control.
• Verify the outlet is properly grounded and not on a faulty neutral or ground circuit (grounding guidance is in the installation guide).
• Make sure both water supply valves are fully open; many cycles will not start correctly if fill conditions are not met.
• If the washer is shaking or “walking,” level it; excessive vibration can trigger interruptions (leveling steps are in the installation guide).

If the basic checks above do not help, these model-relevant parts are common suspects:

A washer that “has power but won’t start” is usually doing its job to prevent unsafe operation. The lid lock and control system are designed to stop the cycle if the lid is not secured, the washer is not set up safely, or the machine cannot confirm normal operating conditions.
