Question 1

the keep warm function on my duo nova seems too hot and burns the bottom of my food.

Accepted Answer

DIAGNOSIS The Keep Warm function maintains a temperature between 145°F and 172°F. For foods with low liquid content (e.g., thick stews, chili), this can cause scorching at the bottom over extended periods. FIX 1. After cooking, do not let the pot automatically switch to Keep Warm. 2. Press Cancel immediately when the timer ends. 3. Perform a Quick Release to stop all heating. 4. Open the lid and stir the contents. 5. Serve or transfer food to a different container for storage. IF THAT DIDN'T WORK If you must use Keep Warm, ensure there is ample liquid in the dish. Add a quarter to a half cup of water or broth and stir thoroughly before activating Keep Warm. HEADS UP The Keep Warm default duration is 10 hours. For most dishes, especially those prone to sticking, 1-2 hours is the practical maximum. The unit will not automatically shut off after 10 hours; it will continue to cycle heat.

Question 2

water keeps leaking from the steam release valve during cooking, even though it's set to sealing.

Accepted Answer

DIAGNOSIS Continuous water leakage from the steam release valve stem indicates the valve is not fully seated in the 'Sealing' position, or food debris is blocking the valve orifice. FIX 1. Press Cancel and allow a Natural Pressure Release until the float valve drops. 2. Open the lid. 3. Remove the steam release valve by pulling it straight up. 4. Wash the valve and its silicone cap under running water, clearing any debris from the small hole. 5. Reinstall the valve, ensuring it clicks fully down onto the lid post. 6. Turn the valve fully to the left to the 'Sealing' position. IF THAT DIDN'T WORK The silicone cap on the valve may be torn or deformed. Inspect it for damage. Order a replacement steam release valve assembly (official Instant Pot part). HEADS UP A small amount of initial condensation or a few droplets from the valve is normal. A steady stream or spray of water/steam is not. Do not attempt to manually hold the valve down during cooking.

Question 3

i get the C6 or C7 error when trying to make yogurt in my duo nova. what does that mean?

Accepted Answer

DIAGNOSIS The C6 or C7 error is a temperature sensor fault during the Yogurt program. The pot cannot reach or maintain the precise low temperature required for fermentation, typically because the inner pot was not at room temperature to start. FIX For C6/C7: 1. Press Cancel. 2. Unplug the unit for 5 minutes to reset. 3. Plug it back in. 4. Ensure your milk mixture has cooled to between 95°F and 115°F (lukewarm, not hot) before placing the inner pot back in the base. 5. Restart the Yogurt program. IF THAT DIDN'T WORK The ambient room temperature may be too cold. Place the unit in a warmer location, away from drafts. Do not use the Yogurt program in a room below 68°F. HEADS UP This error is specific to the Yogurt function. It does not indicate a general failure of the pressure cooking functions. Always use a kitchen thermometer to verify your milk mixture is in the correct temperature range before starting.

Question 4

my instant pot won't turn on at all, no lights, nothing. it's plugged into a working outlet.

Accepted Answer

DIAGNOSIS Complete power failure indicates an issue with the power cord connection, the internal fuse, or a fault in the main control board. No display means no power is reaching the unit's electronics. FIX 1. Verify the wall outlet works with another device. 2. Ensure the power cord is firmly plugged into the back of the Instant Pot base. 3. Check that the cord's connector is fully inserted and not loose. 4. Try a different, known-working power cord if available (standard IEC C13 connector). IF THAT DIDN'T WORK The internal thermal fuse may have blown due to an overload. This requires professional repair or replacement of the unit. Contact Instant Pot customer support; the unit is likely under warranty. HEADS UP Do not attempt to open the base or repair internal components yourself. The base contains high-voltage parts. There are no user-serviceable parts inside.

Question 5

the sealing ring on my duo nova smells terrible, like old food, no matter how much i wash it.

Accepted Answer

DIAGNOSIS The silicone sealing ring is porous and absorbs food odors, especially from pungent ingredients like curry, garlic, or seafood. Standard washing does not remove embedded smells. FIX 1. Remove the ring from the lid. 2. Wash it in hot, soapy water. 3. Use one of these odor-removal methods: Place it on the top rack of a dishwasher cycle. Soak it for 30 minutes in a 50/50 vinegar-water solution. Bake it in an oven at 250°F for 20 minutes. 4. Let it air-dry completely before reinstalling. IF THAT DIDN'T WORK Odors may be permanently embedded. Purchase a replacement sealing ring (official Instant Pot part). Consider designating one ring for savory foods and a separate, new ring for desserts or yogurt. HEADS UP Always ensure the sealing ring is fully seated in its groove in the lid before cooking. A loose or twisted ring will cause pressure loss and may trigger a Burn error.

Question 6

why is my instant pot so loud when it's coming up to pressure? sounds like a hard boil.

Accepted Answer

DIAGNOSIS Rapid, loud bubbling or a 'hard boil' sound is normal during the initial heating phase. This is water boiling vigorously before enough steam is generated to close the float valve and begin pressurization. FIX No fix required. 1. The sound will diminish once the float valve pops up. 2. The display will change from 'On' to the pressure count-up timer. 3. This process typically takes 5-15 minutes depending on contents and quantity. IF THAT DIDN'T WORK If the loud boiling sound persists for over 20 minutes and the float valve never rises, you likely have insufficient liquid. Cancel, cool, and add at least 1 cup of water or broth. HEADS UP This is distinct from a high-pitched hissing or whistling, which indicates the steam release handle is not fully sealed in the 'Sealing' position. Ensure the valve is turned fully to the left.

Question 7

instant pot duo nova keeps blinking '6' or 'L6' and won't do anything when i press a button

Accepted Answer

DIAGNOSIS The L6 or 6 error is a communication fault between the main unit and the lid. The lid sensor cannot confirm the lid is properly closed. FIX 1. Unplug the base for 2 minutes. 2. Plug it back in. 3. Ensure the metal alignment pin on the lid is clean and undamaged. 4. Align the arrow on the lid with the unlock symbol on the base. 5. Close the lid by turning it clockwise until the float valve rises. 6. Try a simple program like Steam for 1 minute. IF THAT DIDN'T WORK Check the silicone sealing ring. Remove it and ensure it is fully seated in its groove in the lid, not pinched or twisted. A misaligned ring can prevent the lid sensor from engaging. HEADS UP Do not attempt to run the pot with this error. The unit will not heat. This is solely a lid detection issue, not a heating element failure.

Question 8

my instant pot duo nova just says 'burn' and won't start pressurizing, what am i doing wrong?

Accepted Answer

DIAGNOSIS The Burn error (BURN or bURN) triggers. This indicates insufficient liquid or food scorched to the bottom during preheating, preventing pressure build-up. FIX 1. Press Cancel. 2. Let the pot cool and release any pressure manually. 3. Open the lid. 4. Check for and remove any stuck food from the bottom. 5. Add at least 1 cup of liquid (water, broth). 6. Stir thoroughly to deglaze the bottom. 7. Close the lid and restart your program. IF THAT DIDN'T WORK The sensor may be oversensitive due to a thin, sugary, or dairy-based sauce. Use the Sauté function to finish cooking the dish uncovered, or transfer to a stovetop pan. HEADS UP The Burn error is a safety feature. Do not force the lid open while the display shows the error. Always ensure the inner pot is fully seated on the heating element.
