Understanding the Problem
What the washer lock sticker is and why it matters: Many new washers ship with a protective adhesive sticker or tape over the door/lid lock area or strike to protect surfaces during transit. If that sticker is left on after installation it can prevent the door/lid from closing or the lock from making electrical contact, so the machine will refuse to start or will flash a door/lock error. Separately, the washer's door/lid lock (also called the interlock or latch assembly) can fail mechanically or electrically and cause the same symptoms. The instructions below show how to check for a sticker first, then how to diagnose and replace a bad lock. Steps — quick checklist and repair sequence: 1) Visual check and sticker removal - Open the door/lid and inspect the lock area (on front‑load: the plastic lock on the cabinet edge; on top‑load: the lid lock on the front lip or rear). Look for any shiny protective film, paper label, or adhesive tape covering the latch or strike. - Peel the sticker off slowly. Use a plastic scraper or fingernail; if residue remains use isopropyl alcohol on a rag to remove adhesive. Re‑close the door and try a short cycle. 2) Note the symptoms and any error codes - If the washer still won’t lock/start, check the control panel for codes such as "dL", "Ld", "Lo", "door", or "F/door". Write them down — they guide diagnosis. 3) Test the door/lid closure and mechanical strike - Close the door/lid and listen for the locking sound (front‑load usually makes an audible engage; top‑load may click). If the door feels loose or the strike doesn’t engage, the strike/hinge may be misaligned or broken. 4) Check for obvious wiring damage - Unplug the washer. Access the lock area (front panel or top console depending on model) and inspect the wiring harness to the lock for disconnected plugs, burned wires, or corrosion. 5) Electrical continuity test (basic multimeter check) - With the washer unplugged, disconnect the lock connector and use a multimeter set to continuity/ohms. Check for continuity between the expected lock terminals (consult your model’s wiring diagram or parts sheet). If the lock has no continuity where it should (or is open when it should be closed), it’s likely bad. 6) Replacement steps (general front‑load door lock replacement) - Unplug washer and turn off water. - Open the door and remove the inner door trim ring or the front panel screws that give access to the lock—procedure varies by model. - Unplug the lock harness and remove the screws holding the lock assembly; remove the old lock. - Install the new lock assembly, secure screws, plug in harness, reassemble trim/panel. - Plug the washer back in and run a diagnostic or a short spin/drain to verify lock operation. 7) Replacement steps (general top‑load lid lock replacement) - Unplug washer. Depending on model, remove the control console or top panel to access the lid lock. - Disconnect the harness, remove the retaining screws or clip, swap in the new lid lock, reconnect and reassemble. - Power on and test. 8) Final tests and calibration - Run a single short cycle (spin or rinse) to confirm the lock engages and the washer runs. If your washer has a diagnostic mode, run the door/lid lock test in diagnostics. Safety note: Always unplug the washer and turn off the water supply before accessing internal components. If you’re not comfortable with electrical testing or removing panels, hire a qualified technician.

Helpful Repair Tip
Before doing any diagnostics, look closely for a protective sticker or tape over the latch — removing it solves many "won't start/door" problems. If no sticker is present, check for error codes and test the lock with a multimeter for continuity.
Frequently Asked Questions
Do I need to remove the sticker before using my new washer?
Yes — many new washers come with a protective sticker or tape over the door lock/strike or on the door gasket. Leaving it on can prevent the latch from engaging or the electrical contacts from closing, causing the washer not to start or to show a lock error. Remove the sticker and any adhesive residue before first use.
How can I tell if the lid/door lock is actually bad?
Start by removing any sticker and checking for error codes. If the error persists, unplug the washer and inspect the lock wiring for loose plugs or burned wires. Use a multimeter to check continuity across the lock terminals (follow the service manual for correct pins and expected readings). If the lock shows no continuity when it should or if you see burned/broken parts, the lock assembly should be replaced. If wiring and lock check out, the control board or harness may be the issue.
