Understanding the Problem
The lid lock assembly on the Whirlpool WTW5100HC3 is responsible for detecting that the lid is closed and for mechanically locking it during certain cycles (especially high-speed spin and some wash settings). When the lock fails, the washer may refuse to start, stop mid-cycle, display lid-related error codes, or fail to advance to spin. Common failure modes include a broken latch, failed internal switch, a burnt solenoid/actuator, or a wiring/connector fault. Because the lock assembly both senses position and provides a locking action, failures can look like control board or motor problems (for example, the washer won't spin or won't start). Start by checking for error codes and observing whether the lock clicks when a cycle is started. In many cases replacing the entire lid lock assembly is the fastest reliable fix, but confirming the root cause (mechanical latch, switch contacts, or wiring) will avoid unnecessary replacement of other parts.
Common Symptoms
Washer won't start or advance, 'lid' or 'door' error codes, no click when cycle starts, stops mid-cycle, or will not enter spin; lid appears unlocked or latch is broken.
Common Causes
- Broken or worn latch/strike that can't engage or hold the lid closed.
- Failed internal switch or solenoid in the lid lock assembly (no electrical continuity or no mechanical action).
- Damaged wiring or connector between the lid lock and the control board (loose, corroded, or pinched harness).

Helpful Repair Tip
Put the washer into diagnostic/self-test mode and listen for a click at the lid area when the lock should engage; also test continuity across the lock switch with a multimeter while actuating the latch—no click and no continuity means the lid lock assembly is likely bad.
Frequently Asked Questions
Can I replace the lid lock assembly myself?
Yes. Basic steps: unplug the washer, open the cabinet or remove the top (depending on model) to access the lid lock, disconnect the harness, remove the mounting screws, swap in the new lock, reconnect the harness, and reassemble. If you’re not comfortable working with electrical connectors or removing panels, consider hiring a technician.
How much does a replacement lid lock cost and how long does the repair take?
Part cost typically ranges from about $25 to $100 depending on OEM vs aftermarket source. Labor for a DIY replacement is usually 20–45 minutes. If hiring a technician, expect labor to add roughly 1–1.5 hours depending on travel and shop rates.
