Whirlpool WTW5640XW0 washer Parts

To reset the lid lock on your Whirlpool WTW5640XW0 washer, we start with a power reset: unplug the washer for 5 minutes, plug it back in, then press and hold Start/Pause for 3 seconds. If the lid still won’t unlock or lock, the lid lock switch may be failing.

• Press Pause/Cancel once to stop the cycle.
• Unplug the washer for 5 minutes (this clears many control glitches).
• Plug it back in.
• Lift and close the lid firmly.
• Press and hold Start/Pause for 3 seconds.
• Start a Rinse/Spin cycle to confirm the lock engages and releases normally.

A lid can stay locked if the control thinks the tub is still moving or water is still present.

• Wait 2 to 3 minutes after the cycle stops (the lock often releases after a short delay).
• If water is still in the basket, run Drain/Spin.
• If it will not drain, check for a drain issue (a clogged pump or kinked hose can keep the lid locked).

Helpful parts to consider for this model:

• Washer lid lock assembly W10404050 (if the lock clicks repeatedly, won’t latch, or won’t sense the lid)
• Washer drain pump assembly WPW10276397 (if the washer won’t drain and the lid stays locked)

If you see these symptoms, replacing the lid lock is the reliable fix because it’s a safety device.

The lid lock prevents spinning with the lid open. If the control can’t confirm a safe lock signal, it may stop the cycle, refuse to spin, or keep the lid locked until it senses the washer is safe.

For model-specific button sequences and diagnostics, follow the WTW5640XW0 installation guide and your use and care information.

The Whirlpool WTW5640XW0 washer has a typical capacity of about 3.6 cu. ft. For the exact rated capacity for your specific configuration, we recommend confirming it in the WTW5640XW0 owner's manual.

Capacity is usually listed in the specifications section of the Use and Care Guide. We use the manual because capacity can vary by closely related model versions.

• Check the Specifications or Features section
• Look for wording such as “capacity” or “cu. ft.”
• If you only see basket size details, use the capacity value listed in the specs (that is the official rating)
• Keep your model and serial information handy when comparing specs

Capacity affects how much laundry you can wash per load and how well the washer can circulate water and detergent around bulky items. Overloading can also contribute to out-of-balance spinning and extra wear on suspension components.

Proper installation helps the washer handle larger loads with less vibration. The installation instructions call for about 1 inch of spacing on all sides to reduce noise transfer; see the WTW5640XW0 installation guide.

The most common problems we see on Whirlpool washers like model WTW5640XW0 are draining or spinning issues and water leaks. Many cases come down to installation setup (drain hose, leveling, inlet hoses) or a worn drive or drain component; the installation guide covers the correct setup checks.

• Won’t drain or leaves clothes wet: drain hose kinked, standpipe issues, or a failing drain pump
• Won’t spin or agitates poorly: worn belt, drive system wear, or a shifting/actuator problem
• Leaks: loose inlet hose couplings, worn hoses, or drain hose not secured correctly
• Loud banging or walking: washer not level, weak suspension, or overloaded/unbalanced loads
• Won’t start: lid not locking, or a control issue

1. Confirm proper water supply: hot and cold faucets within about 3 ft, and water pressure in the typical 20 to 100 psi range.
2. Inspect inlet hoses: use new hoses with flat washers; do not reuse old hoses. Tighten by hand, then about two-thirds turn with pliers (do not overtighten).
3. Verify drain hose routing: secure the drain hose to the tub leg or standpipe so it cannot slip out.
4. Level the washer: leveling reduces excess noise and vibration and helps spin performance.

Drain, spin, and leak complaints often trace back to basic setup details (hoses, drain height, leveling). Getting those right prevents repeat failures and helps protect high-wear parts like the drain pump, belt drive, and lid lock.
