Samsung Washer Door Lock Switch Parts — Models & Compatibility

If your Samsung front-load washer won't start because it thinks the door isn't closed — even when you've slammed it three times — the door lock switch is usually the culprit. This DC34-00026A replacement fits dozens of Samsung WW and WD series models, and it's the same part Samsung service techs install. This hub covers which models use this exact lock mechanism and how to verify yours matches.

Is This the Right Part for Your Model?

Samsung uses this door lock switch across their front-load washer lineup from roughly 2013 onwards, including both washer-only models (WW series) and washer-dryer combos (WD series). Your model number is stamped on a silver label inside the door frame — open the door and look along the top or side edge. Match your full model number against the compatibility list below. If you see WW80K, WW90M, WW85H, WD90J, or similar prefixes, you're in the right place.

About This Replacement Part

The DC34-00026A door lock switch (also sold as AP6002224 or DC3400026A) is the electronic latch assembly that tells your washer's control board the door is securely closed. When it fails, you'll typically see blinking lights, error codes (often dE, dE1, or door-related codes), or the washer simply refusing to fill. The lock mechanism wears out from repeated cycles — most failures happen between year 5 and 8 of ownership. Samsung's design uses a solenoid that can stick or stop engaging entirely, which is why just wiggling the door stops working after a while. This replacement includes the full lock housing with integrated switch, so you're not trying to repair individual components inside a sealed unit.

Why Samsung Door Locks Fail

Samsung's front-load washers cycle this lock mechanism every single load — that's 200+ times per year for most households. The internal solenoid that drives the locking pin eventually wears down its plastic guides or the electromagnetic coil weakens. You'll notice the failure gradually: first the door takes an extra second to lock, then you hear clicking but no lock engagement, then nothing happens at all. Cold laundry rooms make this worse because the plastic components contract slightly, increasing friction on an already-worn mechanism. The lock doesn't just keep the door closed during spin — it's also a critical safety interlock that prevents the drum from spinning with the door open.

Installation Overview

Replacing this door lock requires accessing the front panel of your washer. You'll remove the door boot clamp (the large rubber gasket seal), peel back the boot enough to access the lock mounting screws, disconnect the wire harness, and reverse the process with the new lock. The trickiest part is wrestling the boot clamp back into its groove without pinching the rubber — take your time and work in sections. Most DIYers complete this repair in 30-45 minutes once they've removed the top panel to access the boot clamp properly.

Verifying the Lock is Your Problem

Before ordering, confirm the door lock is actually faulty. Close the door and listen carefully — do you hear clicking but no solid "thunk" of the lock engaging? Try gently pushing on the door while starting a cycle. If the washer sometimes starts with extra pressure on the door, the lock mechanism is weak. Check for error codes: dE means door error, dE1 often means the lock engaged but the sensor isn't reading it correctly, and dE2 usually indicates the lock button (AddWash models) is stuck. If you see standing water in the drum, don't assume it's the lock — Samsung washers won't unlock with water present, which might be a separate drain issue.

Price and Availability

The DC34-00026A replacement lock retails for $36.99, which is significantly less than a service call ($120-180 in most areas just for the technician to show up). Samsung dealers sometimes stock this part, but aftermarket suppliers like Heima keep consistent inventory since it's such a common failure point. The part number crosses with AP6002224 and DC3400026A, so you might see it listed under any of those SKUs — they're all identical assemblies from Samsung's OEM production line.
