Understanding the Problem
Brief explanation: The lid lock (sometimes called the lid switch or lid latch assembly) on the Whirlpool WTW5000DW1 detects whether the lid is closed and safely allows the washer to agitate and spin. When the lock/latch fails the washer may not start, won't spin, displays a lid-lock error, or locks and won’t unlock. Step-by-step diagnostic & repair instructions: 1) Confirm the symptoms: note if washer won’t start, won’t spin, shows “LO” or a lid-lock code, the lid stays locked after cycle, or you hear repeated clicking near the lid. 2) Power safety first: unplug the washer or turn off the house breaker before beginning any inspection or repair. 3) Visual inspection: open the lid and inspect the latch striker on the lid and the latch assembly on the cabinet. Look for broken plastics, melted parts, or corrosion on the wiring connector. 4) Access the lid lock: on most WTW5000-series washers remove the screws at the back of the top panel, slide the top forward and lift to access the lid lock assembly near the hinge area. 5) Test continuity on the lid switch (basic multimeter test): set meter to ohms. Disconnect harness from the lock assembly. With the lid closed (or by gently pressing the actuator), you should see continuity between the switch terminals. If there’s no continuity when the actuator is engaged or it is intermittent, the lock is bad. 6) Test for voltage (advanced): with the washer plugged in and a helper starting a cycle that should lock the lid, carefully measure the control output voltage to the lid lock connector (use caution; live-voltage test). If control is sending voltage but lock does not engage, replace the lock. If there is no voltage sent to the lock, suspect wiring or the main control board. 7) Inspect wiring & connectors: check for frayed wires, burned connectors, or a loose connector. Repair wiring with proper splices or replacement harness if needed. 8) Replace the lid lock assembly (how to fix): a. Order the correct replacement part for WTW5000DW1 (verify with the model/serial tag). b. Unplug washer. Remove top panel screws at the rear, slide top forward, and lift. c. Locate the lid lock assembly and unplug the wiring harness. d. Remove mounting screws/clips holding the lock and take out the assembly. e. Install the new lock: position it, secure screws/clips, reconnect harness. f. Reinstall the top panel, secure screws, plug in washer, and run a test cycle. 9) If replacing the lock does not fix the issue: re-check wiring to control and test the main control board outputs. A faulty board can also prevent the lock from energizing. Safety note: Always disconnect power before disassembling. If you’re uncomfortable testing live voltage or working near mains, hire a qualified appliance technician.
Common Symptoms
Washer won’t start or spin, displays lid-lock error code, lid stays locked after cycle, clicking at lid, or intermittent start/stop behavior.
Common Causes
- Failed lid lock / lid switch assembly (worn microswitch or broken actuator)
- Broken latch striker or damaged lid catch (mechanical failure)
- Damaged wiring/connectors or a faulty main control board not sending power to the lock

Helpful Repair Tip
With the harness disconnected, press the actuator and check continuity with a multimeter; no continuity when pressed = replace the lid lock assembly.
Frequently Asked Questions
How do I know if the lid lock or the control board is bad?
First test the lid lock for continuity and visually inspect wiring. If the lock shows no continuity when actuated, it’s bad. If the lock is good but it never receives voltage during a cycle, the wiring or main control board may be at fault. Voltage tests at the connector during a run cycle will show whether the control is sending power to the lock. If you’re not comfortable doing live-voltage tests, replace the inexpensive lid lock first — it’s the most common failure.
Can I bypass the lid lock to make the washer work?
You should not bypass the lid lock. It’s a safety device that prevents the washer from agitating or spinning with the lid open. Bypassing can create a serious safety hazard, may damage the washer, and void warranties. Always repair or replace the proper part.
