Samsung Front Load Washer Door Lock Switch Parts — WF45K, WF50K & WW90K Series Compatibility

Your Samsung front-loader won't start and just sits there beeping at you. The door feels locked, but the washer refuses to run. Nine times out of ten, it's this door lock switch assembly — the DC34-00025D — that's failed. This hub covers replacement door lock switches for Samsung's WF45K, WF50K, and WW90K series washers, plus compatible combo units like the WD13J and WD18J models.

Is This the Right Part for Your Model?

Check your washer's model number before ordering. On most Samsung front-loaders, you'll find it on a sticker inside the door frame or on the back panel near the water connections. This DC34-00025D lock assembly (replaces AP6025317, PS11758871, and EAP11758871) works across multiple series, but confirming your exact model prevents returns.

Common compatible models include WF45K6200AW, WF45K6500AV, WF50K7500AW, WW90K74150OX, and WD13J7825KP. The complete compatibility list below shows all verified fits — notice the pattern: if your model starts with WF45K, WF50K, WW90K, or WD13J through WD18J, you're likely covered.

About This Replacement Part

The door lock switch assembly does two critical jobs: it mechanically latches your washer door shut, and it signals the control board that it's safe to start the wash cycle. When it fails — usually after 5-7 years of daily use — your washer displays error codes like dE, dC, or door, and refuses to run even though the door seems closed.

This is a direct OEM replacement that includes the complete locking mechanism and electrical switch. You're not just replacing a plastic latch — the entire electronic assembly gets swapped out, which is why most DIYers can handle this repair in under 30 minutes with just a screwdriver. The lock mounts to the door frame with two screws and connects via a simple wire harness plug.

Why This Part Fails

Samsung front-loaders run hot wash cycles that create steam and humidity inside the door seal area. Over thousands of cycles, this moisture corrodes the electrical contacts inside the lock switch. The mechanical latch also wears down from the constant lock-unlock action — especially if you've ever forced the door open during a cycle (we've all done it).

The WF45K and WF50K series are particularly prone to premature lock failure because of their high-efficiency steam wash features. The extra heat accelerates contact corrosion. If your washer is 4-6 years old and suddenly won't latch, this switch assembly is almost always the culprit.

Installation Overview

You'll need to peel back the front door boot seal to access the lock assembly mounting screws. Don't remove the entire boot — just pull the inner lip away from the door frame enough to see the lock mechanism. Remove the two mounting screws, disconnect the wire harness, and reverse the process with your new lock.

Most people get tripped up trying to reinstall the boot seal properly. Here's the trick: start at the 6 o'clock position and work your way around, making sure the seal lip sits fully in its channel. Run an empty test cycle before loading laundry to verify the door locks properly and the error code is gone.

Cross-Reference Numbers

This DC34-00025D lock switch replaces several part numbers you might see listed in Samsung documentation or on parts sites: AP6025317, PS11758871, and EAP11758871. They're all the same part with different supplier codes. If your repair manual or service tech quoted any of these numbers, this is your replacement.
