You just unboxed it. The Instant Pot Duo Plus manual is sitting on your counter, likely covered in a light dusting of flour or a splash of stray coffee, and you’re staring at that "V2" or "V3" interface wondering why there are twenty buttons for things you’ll probably never cook. Honestly? Most people feel a surge of "what have I done" the second they see the steam release handle. It looks like a weapon. It sounds like a jet engine. But once you get past the initial intimidation factor, this specific model—the Duo Plus—is actually a massive upgrade over the classic Duo, provided you know which parts of the manual to follow and which parts to basically ignore.
The Duo Plus is a bit of a middle-child in the Instant Pot lineup. It’s fancier than the basic Lux or Duo because it has that blue LCD screen and extra programs like "Sterilize" and "Sous Vide," but it’s not quite the "smart" Wi-Fi enabled Pro version. It’s the sweet spot for people who want to cook a roast in 45 minutes but also maybe want to make their own yogurt on Sundays.
The Water Test: Don’t Skip the "Init" Phase
Look, I know you want to throw a frozen chicken in there immediately. Don't. Every Instant Pot Duo Plus manual practically begs you to do the "Initial Test Run," and for once, the corporate instructions are right. It's not about cleaning the pot—though it does that too—it’s about making sure your sealing ring isn’t defective.
Fill the inner pot with 3 cups of water. Lock the lid. You’ll hear that little "jingle" the pot plays. Make sure the steam release valve is set to "Seal." On the Duo Plus, this is usually an automatic toggle, but double-check. Select "Pressure Cook" (or "Manual" on older versions) and set it for 5 minutes.
It’s going to hiss. That’s normal.
It’s going to smell a little bit like hot plastic. Also normal for the first run.
Once the little silver float valve pops up, the pot is pressurized. If steam keeps escaping from the edges of the lid after five minutes, your sealing ring isn't seated right. This 10-minute test saves you from wasting a $20 pot roast later because the liquid evaporated and gave you the dreaded "Burn" notice.

Understanding the Duo Plus Interface vs. Reality
The LCD screen on the Duo Plus is great because it actually tells you what’s happening. It says "On" while it's heating, then it switches to the countdown timer once it hits pressure. But the buttons? They’re mostly just pre-set timers.
The "Poultry" button isn't magic. It doesn't have a sensor that knows how much chicken is in there. It just defaults to a specific pressure level and time. Most veteran users—the people who actually use these things every day—almost exclusively use the Pressure Cook button and the +/- keys. Why? Because a large frozen chicken breast takes a different amount of time than a pile of wings, and the "Poultry" button doesn't know the difference.
The Most Important Page in the Instant Pot Duo Plus Manual
If you actually flip through the booklet, find the section on Natural Release (NR) vs. Quick Release (QR). This is where most beginners mess up their food.
- Quick Release: You flick the switch and a geyser of steam shoots up. Use this for veggies, delicate fish, or anything you don't want to turn into mush.
- Natural Release: You do nothing. You wait 10 to 20 minutes. The pressure drops slowly as the pot cools. Use this for meat. Always. If you Quick Release a beef stew, the sudden change in pressure literally sucks the moisture out of the muscle fibers. You'll end up with meat that is somehow both wet and "dry" or chewy.
The Duo Plus features the "Easy Release" switch, which is a total lifesaver for your fingers. Unlike the old models where you had to nervously nudge a hot weighted valve with a wooden spoon, this one has a dedicated button away from the steam vent.
Why the "Burn" Error Happens (and how to fix it)
You’re halfway through making chili and the screen flashes "Burn." It’s a heart-sinking moment. Basically, the sensors at the bottom of the Duo Plus have detected that the inner pot is too hot, which usually means food is stuck to the bottom and scorching.
The most common culprit? Tomato sauce. Or flour. Or not enough thin liquid.
The Instant Pot Duo Plus manual explains that the pot needs thin liquid (water, broth, juice) to create the steam that builds pressure. If you put a thick jar of marinara on the bottom, it won’t boil; it’ll just bake onto the stainless steel.
Pro Tip: Layer your ingredients. Put your meat and broth in first. If the recipe calls for tomato paste or thick sauces, "float" them on top. Do not stir. The pot will still cook everything, but the bottom stays clear of the thick stuff that triggers the sensor.
Cleaning the Bits Nobody Talks About
You can't just throw the lid in the dishwasher and call it a day. Well, technically the manual says the lid is top-rack dishwasher safe, but there’s a catch. You have to pull off the silicone sealing ring and the "anti-block shield." That’s the little metal mesh cap on the underside of the lid.
If you don't clean under that shield, old food particles (like a single rogue grain of rice) can get stuck. Next time you cook, that grain of rice prevents the pot from sealing. You’ll be standing there for 20 minutes wondering why it’s not pressurizing while your kitchen turns into a sauna.
Also, that little plastic cup on the back? That's the condensation collector. It catches the drips when you open the lid. Empty it. If you forget, it turns into a science project within a week. Honestly, it’s the grossest part of the machine if neglected.
The Sous Vide Function: Is it Legit?
The Duo Plus is one of the cheaper models to include a Sous Vide program. If you’ve read the Instant Pot Duo Plus manual section on this, it sounds complicated, but it’s just a slow water bath.
Is it as accurate as a $200 dedicated immersion circulator? No. But for a steak or a piece of salmon? It’s surprisingly solid. The trick is to use hot tap water to start so the pot doesn't take 45 minutes just to reach 130°F. Since the pot is insulated, it actually holds the temperature quite well once it gets there.
Practical Steps for Your First Real Meal
- Check the Ring: Give the silicone ring a tug to make sure it's snug in the rack.
- The 1-Cup Rule: Never, ever try to pressure cook with less than 1 cup of liquid (for the 6-quart model). The 8-quart usually needs 1.5 to 2 cups.
- Sauté First: Use the Sauté function to brown your meat. It adds flavor (the Maillard reaction) and pre-heats the pot so it gets to pressure faster.
- Deglaze: After sautéing, pour in a splash of broth and scrape the bottom of the pot with a wooden spoon. Those brown bits are delicious, but if they stay stuck, they’ll trigger the "Burn" notice.
- Seal and Walk Away: Set your time, make sure the valve is set to seal, and go do something else.
The beauty of the Instant Pot Duo Plus isn't that it's "instant"—a pot of beans still takes an hour when you account for the time to reach pressure—it's that it's "unattended." You aren't standing over a stove. You aren't worrying about a pot boiling over.
Once the timer beeps, check your recipe to see if it needs a 10-minute Natural Release. If you're doing eggs (5-5-5 method: 5 mins pressure, 5 mins natural release, 5 mins ice bath), pay close attention to that clock. Overcooking eggs in a pressure cooker leads to those unappealing green rings around the yolks.
If you’ve lost your physical copy of the Instant Pot Duo Plus manual, you can find the PDF on the Instant Home official website, but honestly, the most important takeaway is this: keep the rim clean, keep the bottom deglazed, and always make sure that silicone ring hasn't stretched out. If the ring feels loose or smells like last week's curry, it’s time to buy a two-pack of replacements. They're cheap, and having a "sweet" ring for cheesecakes and a "savory" ring for chili is the ultimate pro move.
Actionable Maintenance Checklist
- Every Use: Wash the inner pot and the sealing ring. Wipe the condensation track.
- Every 5 Uses: Remove the anti-block shield (the metal steam cap) and clean it. Check the float valve for stickiness.
- Every 3 Months: Inspect the power cord for any fraying and check the sealing ring for cracks or "give." If the ring is yellowed and smells, soak it in a 50/50 mix of water and white vinegar.
- The "Deep Clean": Use a damp cloth to clean the heating element inside the base (ensure it's unplugged and totally cool). A Q-tip is great for getting into the narrow rim where the lid locks.
Following these steps keeps the machine running exactly how the engineers intended, even if the manual is currently buried under a pile of mail in your kitchen.
