Quick Answer
To find your Samsung parts diagram, look for the silver sticker inside the door or on the back of the washer cabinet. Most Samsung front loaders start with the prefix WF, where W stands for washer and F signifies it is a front loading model.
Look, I can't tell you how many times someone orders a door boot seal using the wrong diagram and ends up with a part that's two inches off. Samsung reuses model number prefixes across totally different machines. Getting the right model string, including that little version code at the bottom, is honestly the difference between a $30 fix and a $30 mistake plus another week of waiting on the correct part to show up.

Samsung Washer Parts Diagram & Model Number Lookup
Samsung's front loader lineup is actually pretty organized once you know the code. WF means front load washer, the next two digits are roughly capacity, and the letters after that tell you the series year and finish color. The tricky part? They updated motors, boards, and even door seal designs mid-production run on some models, so two machines with almost identical model numbers can need completely different parts. I ran into this exact situation three times last month alone.
Where is the model number on a Samsung front loader?
Nine times out of ten it's on the inside of the door frame, right where the door closes against the machine. Open the door all the way and look at the rim of the opening. If it's not there, the next place is the upper right corner of the back panel. Samsung also sometimes put a smaller sticker on the right side panel, about halfway up. On a handful of older models I've worked on there was a sticker on the main control board inside the top access panel, but that requires some disassembly and I'd only go there as a last resort.
What does the WF mean in my model number?
W is for Washer, F is for Front Load. So WF basically just says 'this is a front-loading washing machine.' The numbers right after that, like 42, 45, or 50, are roughly the drum capacity in cubic feet, though Samsung's not always perfectly consistent about it. Then you've got letters that indicate the series year, the color finish (AW is usually white, AV is black stainless or graphite), and sometimes a retailer-specific code. It sounds complicated but once you see a few model numbers it starts to click pretty fast.
Why do I need a version code for a parts diagram?
Because Samsung updates parts mid-production run without always changing the main model number. I've ordered drain pumps for a WF45 before and gotten the wrong one because I skipped the BOM code. The version is usually a two-digit number on the same sticker. Parts suppliers need it to narrow down which exact revision of the machine you have. Without it you're gambling. Some parts are interchangeable between revisions and some absolutely aren't. The door boot seal is a big one where this matters, and those run $40 to $80 depending on the model.
Can I use a WF42 diagram for a WF45 model?
Don't do it. I know they look the same on the outside and some of the sheet metal is actually identical between those two, but the control board pinout, the motor harness routing, and the tub suspension are all different. The capacity difference isn't just a number, the whole tub assembly is physically larger on the 45 cubic foot version. If you're looking at a door latch or a hose clamp you might get lucky. But for anything electrical or anything that bolts directly to the tub, you need the right diagram.
What if my model sticker is missing or unreadable?
First check your original paperwork, the manual box, or any old emails if you bought it online. A lot of people have the model number buried in a Home Depot or Best Buy order confirmation somewhere. If that's gone, try the main control board inside the top panel, there's sometimes a sticker there. You can also open the Samsung SmartThings app if your washer is WiFi-connected, it sometimes shows the full model string. Last resort, call Samsung support with the serial number if that's still readable and they can usually look it up.
How do I read a Samsung parts diagram once I have my model number?
Enter your full model string into any major parts supplier site and you'll usually see an exploded diagram with numbered callouts. Click the section you need, like the pump area or the door assembly, and it breaks out into individual parts with specific part numbers. Always write down the part number itself, not just the description, because descriptions can be vague. Two parts might both be called 'drain pump' but have completely different connectors. The part number is the only thing that guarantees you're ordering the exact right piece for your specific machine.
My Samsung model number ends in /AA or /XAA, what does that mean?
That's a region code. XAA or just AA means the unit was sold in North America. You'll sometimes see XAC for Canada or XEF for European models. This matters when you're ordering parts because a European version might have different voltage components. For most people in the US it'll be XAA or AA and that's fine. Just include it when you're searching for parts to make sure you're getting the right regional spec. Some suppliers filter by this code and others don't, but it's always better to include it than leave it out.
