Understanding the Problem
Brief explanation: The lid lock (aka lid latch or lid switch assembly) on a Whirlpool WTW5000DW2 secures the top during the wash/spin cycle and tells the control board the lid is closed. When it fails the washer may refuse to start, stop mid-cycle, show lid-related error codes, or run but not agitate/spin. Step-by-step diagnostic and repair instructions: 1) Confirm symptoms and error codes: - Note what the washer does: won’t start, stops during spin, shows error codes (LO, LC, or similar), or a flashing light pattern. Write down any displayed codes or unusual behavior. 2) Safety first: - Unplug the washer or turn off the breaker before touching wiring or removing panels. 3) Visual inspection: - Open the lid and inspect the lid strike/latch area for broken plastic, loose screws, or foreign objects. Check the actuator on the lid and the lock body for cracks. - Inspect wiring harness and connector at the lock for corrosion, burned insulation, or loose pins. 4) Listen / observe during a cycle: - With the washer powered on and a cycle started, stand by and listen for a mechanical “click” from the lid lock when the washer should lock. No click may indicate a dead lock or no power to it. 5) Simple continuity test (cold test): - Unplug washer. Disconnect the lid lock connector. Set a multimeter to continuity or ohms and test the lock terminals per manufacturer wiring (two or three terminals). A totally open circuit when the lid is actuated/closed often indicates a failed switch inside the assembly. 6) Voltage test (only if comfortable & safe): - If you know how to work safely with live voltage, plug the washer back in, start a cycle that should lock the lid, and carefully back-probe the lock connector with the multimeter set to AC volts to confirm the control board is supplying ~120VAC (or the expected control voltage) to the lock. If there is voltage but the lock does not operate, the lock is bad. If there is no voltage, the control board, timer or related interlocks may be the cause. 7) Bypass-check (diagnostic only): - For testing only (DO NOT USE PERMANENTLY): you can momentarily simulate a closed lid by temporarily connecting the lock’s closed-signal pair (follow wiring diagram). This can confirm whether the rest of the washer functions when the lock signal is present. If the washer runs normally when the lock is jumped, the lock assembly is the likely fault. 8) Remove and replace the lid lock assembly: - Unplug the washer. - Open the lid and locate the screws or clips holding the top panel/console (usually at the back of the console or under the rim). Remove the mounting screws to tilt/raise the console or top. - Locate the lid lock assembly (front of the top). Disconnect the wire connector, remove the mounting screws, and remove the old lock. - Install the replacement lock, reconnect the harness, secure the top/console, and restore power. 9) Test the repair: - Run a short spin or drain cycle and confirm the lock clicks, the washer recognizes the lid closed, and the washer runs a full cycle including spin. Safety note: Always unplug the washer before accessing internal components. If you perform live voltage checks, use appropriate PPE and tools and only do so if you are experienced with electrical measurements — otherwise leave voltage testing to a trained technician.
Common Symptoms
Washer won’t start or will stop mid-cycle; shows lid-related error codes; no audible click when cycle starts; washer won’t spin or agitate even when lid closed.
Common Causes
- Failed lid lock switch or solenoid inside the lock assembly
- Damaged or corroded wiring/connectors to the lid lock
- Control board or board relay not supplying power to the lock (less common)
- Broken lid strike or misaligned top preventing the lock from engaging

Helpful Repair Tip
If the washer has power to the lock connector during a lock-attempt but you hear no click and the lock shows no continuity, replace the lid lock assembly — that combination almost always points to a failed lock.
Frequently Asked Questions
How can I tell if the lid lock itself is bad?
Check for an audible click when a cycle starts that should lock the lid. With power removed, disconnect the lock and test continuity across the switch terminals — a failed internal switch often shows no continuity where it should. If the control is sending voltage to the lock during a lock attempt but the lock doesn't actuate, the lock assembly is almost certainly bad.
Can I bypass the lid lock so the washer will run?
Temporarily jumping the lid-closed signal can be useful for diagnosing, but bypassing the lid lock is unsafe and not recommended for regular use. The lock prevents the lid from opening during agitation/spin and is a safety device. If you must test, do a momentary jumper only to confirm other components; then restore proper wiring and replace the faulty lock.
