Samsung Dishwasher Door Latch Switch Parts — Models & Compatibility

Your Samsung dishwasher won't start, and the control panel's acting like the door is wide open even when it clicks shut. That's the door latch switch failing — it's the safety component that tells your dishwasher the door is properly closed and locked before allowing a cycle to begin. This hub covers the DD81-01629A replacement latch switch for Samsung DW80 series dishwashers, including the F600, J3020, K5050, K7050, and R5060 model families.

Is This the Right Part for Your Model?

Check your dishwasher's model number, which is typically found on a sticker inside the door edge or along the side of the tub opening. You're looking for model numbers starting with DW80F, DW80J, DW80K, or DW80R followed by four digits. Compatible models include DW80F600UTB/AA, DW80J3020US/AA, DW80K5050UW/AA, DW80K7050UG/AA, and DW80R5060US among others. The DD81-01629A replaces older part numbers AP5800420, PS8764558, DD81-02132A, and AP6287051.

About This Replacement Part

The door latch switch is a dual-function component mounted in the dishwasher door frame. When you close the door, the latch mechanically secures it shut while simultaneously activating an electrical switch that signals the control board it's safe to run. When this switch fails, you'll see two primary symptoms: the door won't stay latched closed, or it closes but the dishwasher refuses to start because it thinks the door is open. Some units will display error codes, while others simply sit silent with no response when you press Start.

Installation Overview

Before you begin, unplug the dishwasher or shut off the house circuit breaker — you'll be working with electrical connections. Wear work gloves to protect your hands from sharp metal edges inside the door frame. The switch typically mounts with two screws behind the inner door panel, and you'll need to disconnect a wire harness. Most repairs take 30-45 minutes once you have the door panel removed.

What Causes Door Latch Switch Failure?

These switches wear out from repeated use — every time you open and close the door, the latch mechanism cycles. Over thousands of cycles, the plastic components can crack, the spring tension weakens, or the electrical contacts inside corrode. Hard water areas see faster failure rates because mineral deposits can interfere with the latch mechanism. If your dishwasher is 5+ years old and the door suddenly won't latch or the unit won't recognize a closed door, this switch is the likely culprit.

Need Help Finding Your Model Number?

Samsung places the model and serial number tag in one of three locations: on the left or right side of the door opening (visible when you open the door), or on the top edge of the door itself. Look for a white sticker with a barcode — the model number is the alphanumeric code that starts with "DW" followed by numbers and letters. Write down the complete model number including the suffix after the slash (like /AA or /AC) to ensure proper fitment.
