Understanding the Problem
The lid lock assembly on the Whirlpool WTW5100HC3 is a safety interlock that prevents the washer from agitating or spinning while the lid is open and holds the lid closed during certain cycles. When the lid lock fails it can prevent the washer from starting, stop cycles mid-way, or leave the lid stuck locked after a cycle completes. Failures may be electrical (switch or solenoid), mechanical (broken latch/plastic), or caused by wiring/connectors. Diagnosing a lid lock issue includes checking for obvious broken or melted plastic on the latch, listening for a click when the machine attempts to lock, watching for related error codes on the control panel, and testing the switch/actuator with a multimeter. If the assembly is faulty it should be replaced — the part includes the latch, actuation switch, and wiring connection specific to the top lid of this model.
Common Symptoms
Washer will not start, washer pauses and shows error, lid stays locked after cycle, no audible click when locking, intermittent locking/unlocking, or washer won’t spin/agitate because it 'thinks' the lid is open.
Common Causes
- Failed lid lock switch or solenoid inside the lid lock assembly
- Broken or worn mechanical latch (plastic catch/strike) preventing proper actuation
- Damaged wiring harness or poor connector contact between lock assembly and control board

Helpful Repair Tip
Unplug the washer, open the top panel and manually operate the latch while testing continuity across the lock switch with a multimeter. If the switch does not change state when the latch is actuated (or you hear no click from the lock solenoid during a cycle), the lid lock assembly is likely the faulty part.
Frequently Asked Questions
How do I replace the lid lock assembly on a WTW5100HC3?
Unplug the washer. Remove or tilt the control console (follow model service instructions) to access the top panel fasteners, then remove the top panel to reach the lid lock area. Disconnect the wiring harness from the lock assembly and remove the screws holding the lock in place. Install the new assembly, reconnect the harness, reassemble the top panel and console, then test a short cycle. If uncomfortable with electrical repairs, hire a qualified appliance technician.
Can I bypass the lid lock to get the washer running?
No. Bypassing the lid lock is unsafe and not recommended. The lid lock is a safety device preventing the tub from spinning with the lid open. Bypassing can create serious injury risk and may void warranties or violate local codes. Diagnose and replace the failed lock assembly instead.
