The lid lock assembly is the most common cause of a top-load washer that won't start or displays a lid lock error. The lid lock both physically locks the lid during the spin cycle and sends an electrical signal to the control board confirming the lid is closed. When the lock mechanism or its internal switch fails, the washer refuses to start or stops mid-cycle as a safety precaution.
Symptoms: Lid lock error code, washer won't start, lid lock clicking without engaging, washer stops before spin
→ Shop GE Washer Lid Lock Assembly WW03F00016The lid strike is the plastic tab on the washer lid that inserts into the lid lock assembly to trigger the locking mechanism. If the strike is broken, worn, or misaligned, the lid lock sensor never detects a closed lid even when the lid is shut. Inspect the strike for cracks or deformation before replacing the full lid lock assembly.
Symptoms: Lid lock error even with lid fully closed, lid lock doesn't click when lid closes
→ Shop Washer Lid PartsThe main control board interprets the signal from the lid lock and controls the washer's cycle progression. If the control board fails to read the lid lock signal correctly — even when the lid lock itself is functioning — the washer will display a lid lock error or refuse to start. This is a less common cause but should be investigated after confirming the lid lock and wiring are good.
Symptoms: Lid lock tests good but error persists, multiple error codes, erratic cycle behaviour
→ Shop Washer Control BoardsThe wiring harness connecting the lid lock to the control board can become pinched, frayed, or corroded over time — especially if the washer lid has been slammed repeatedly. A damaged wire in the harness can cause intermittent or permanent lid lock errors even when the lid lock assembly itself is in good condition. Inspect the harness for visible damage before replacing parts.
Symptoms: Intermittent lid lock errors, error clears temporarily then returns, visible wire damage near lid hinge
→ Shop Washer PartsBefore diagnosing internal components, confirm the washer is receiving proper power. A tripped GFCI outlet, a loose power cord connection, or a tripped circuit breaker can prevent the washer from starting entirely — with no error codes displayed. Test the outlet with another appliance and check the breaker panel before opening the machine.
Symptoms: Washer completely dead, no lights or display, no response to any button
→ Shop Washer PartsSome washers will pause mid-cycle and display an error if the load is severely unbalanced or overloaded. The machine may interpret the excessive vibration as a safety issue and lock the lid to prevent damage. Redistribute the load, remove some items, and restart the cycle before replacing any parts.
Symptoms: Error occurs mid-cycle, excessive vibration before error, error clears after redistributing load
→ Shop Washer PartsA persistent lid lock error almost always means the lid lock assembly has failed. The internal switch or solenoid in the lock has worn out and is no longer sending the correct signal to the control board. Replacing the lid lock assembly is the most reliable fix. If the lid lock tests good, the main control board may be the cause — see the W11742939 Whirlpool Washer Main Control Board for compatible Whirlpool models.
Yes — try unplugging the washer for 60 seconds, then plugging it back in. This resets the control board and clears temporary faults. If the error returns immediately or after the next cycle, the lid lock assembly or control board needs to be replaced.
OEM washer lid lock assemblies typically cost $60–$90 CAD. DIY installation takes 20–45 minutes and requires only basic tools, saving significantly on labour costs. XPart Supply offers OEM lid lock assemblies with fast Canadian shipping and guaranteed fit for your model.
No — bypassing the lid lock is dangerous and strongly discouraged. The lid lock prevents the washer lid from opening during the high-speed spin cycle, which can cause serious injury. Always replace a failed lid lock rather than bypassing it.
