LG Washer Door Lock Switch Assembly Parts — Models & Compatibility

Your LG washer won't start, and you hear clicking at the door but nothing happens. That's the door lock switch assembly failing—one of the most common failure points on LG front-load washers from 2005-2015. This hub covers the 6601ER1004C replacement part (replaces EBF49827801, EBF49827802, AP4998848, PS3533609) and which models it fits.

Is This the Right Part for Your Model?

Check your washer's model number label—it's inside the door opening on the door frame or behind the dispenser drawer. Match it against the compatibility list below. This part fits LG washers in the WM series from 2005-2015, including WM2277, WM2301, WM2442, WM2601, WM2701, WM2801, WM2901, and WM3001 series models. If your model starts with "WM" and you've got locking issues, there's a good chance this is your part.

About This Replacement Part

The door lock switch assembly does two critical jobs: it physically locks the door when a cycle starts, and it signals the control board that it's safe to fill with water. When it fails, you'll typically see one of three symptoms: the washer won't start at all, the door won't latch properly, or you'll hear repeated clicking as the lock tries to engage but can't. The switch assembly includes the locking mechanism, the wiring harness connector, and the interlock switch—all in one unit. This replacement part (6601ER1004C) is the direct OEM-equivalent assembly that restores full functionality.

Common Symptoms That Point to This Part

Here's what you'll notice when the door lock assembly goes bad:

• Will Not Start — Control panel lights up, you press start, nothing happens. Door lock clicks but doesn't engage.
• Lid or door won't close — The door feels loose or won't catch properly when you close it.
• Locking Issues — Door locks and unlocks randomly, or stays locked after the cycle ends.

If you're experiencing any of these, the door lock assembly is the first thing to test. It's a straightforward replacement that takes about 20 minutes once you've got the part.

Why This Part Fails

The door lock assembly sits right in the door strike area, which means it takes physical abuse every time you close the door. Over time, the plastic locking tab wears down, the internal switch contacts corrode from humidity, or the wiring connector gets loose from vibration. LG washers from this era are known for door lock failures around the 7-10 year mark. It's not a design flaw—it's just wear and tear on a mechanical part that cycles thousands of times.

What's Included

The 6601ER1004C assembly includes:

• Complete door lock mechanism with mounting bracket
• Integrated wiring harness with connector
• Interlock safety switch

You don't need to buy any additional components—this is the complete assembly ready to install.
