Samsung Dishwasher Door Switch Parts — Models & Compatibility

If your Samsung dishwasher won't start, runs with the door open, or displays error codes related to the door latch, the door switch is often the culprit. This DD34-00007A door switch is the OEM-quality replacement for dozens of Samsung dishwasher models, particularly the popular DW80J and DW80M series built between 2015 and 2019.

The door switch is a small but critical safety component that tells your dishwasher control board whether the door is securely closed. When it fails, your dishwasher simply won't run — even if everything else works perfectly.

Is This the Right Part for Your Model?

This door switch fits over 30 Samsung dishwasher models. You'll find your model number on a sticker inside the door frame — open the door and check the left or right edge. Look for a model number starting with "DW80" followed by a letter-number combination.

Common compatible series include DW80J7550, DW80J9945, DW80M9550, and DW80M9960. The part number DD34-00007A replaces older numbers AP5917184, PS9606356, and 3554013, so if you're finding any of those numbers in your research, you're in the right place.

About This Replacement Part

The DD34-00007A is a door-mounted interlock switch that Samsung integrated into their premium dishwasher lines starting around 2015. It's located near the door latch assembly and uses a spring-loaded contact mechanism to detect door closure. Unlike cheaper aftermarket versions, this replacement maintains the same contact pressure and electrical specifications as the factory original.

Door switch failures typically happen after 4-6 years of normal use. The spring mechanism weakens, or the electrical contacts oxidize from humidity exposure. You'll know it's failed when the dishwasher completely refuses to start, or if the control panel lights up but nothing happens when you close the door and press start.

This switch works in conjunction with your dishwasher's door latch — if you're experiencing issues, it's worth checking both components. Sometimes what looks like a latch problem is actually a failed switch, and vice versa.

Why Choose This Replacement?

At $53.99, this OEM-equivalent door switch costs less than a single service call. It's the same part Samsung technicians install, which means you're getting factory-level quality without the dealer markup. The DD34-00007A uses the same mounting points, wire connectors, and spring mechanism as your original switch — no modifications needed.

Most DIYers complete this repair in under 20 minutes. You'll need to remove the inner door panel (usually 6-8 screws around the perimeter), disconnect the wire harness, swap the switch, and reassemble. The hardest part is typically keeping track of the screws.
