Class action alleges Instant Pot Duo lid-locking assemblies fail, allowing lids to open under pressure
The class action names the IP Duo Series among the affected models. The defect is a lid that can open while the cooker is still pressurized, ejecting super-heated contents.
What to check. Never force the lid open; always confirm the float valve has dropped and pressure is fully released before opening. If the lid opens while pressurized, stop using the unit immediately.
Instant Pot Duo bought in Turkey failed after about one month; warranty support unreachable
A Dutch Amazon review (March 2026) states the reviewer's brother bought a Duo in Turkey and it stopped working after about a month; Amazon Turkey directed them to Turkish warranty service, but the phone numbers found did not work. This documents both a failure in the Turkish market and difficulty accessing warranty support.
What to check. Before buying in Turkey, confirm the warranty service path and keep the invoice; the complaint indicates Turkish warranty phone numbers may be non-functional.
Instant Pot Duo Turkish manual documents Food Burn and PrSE error codes
The official Turkish-language manual for the Duo (Instantpot.co.uk, Duo-UK-TUR-Full_Manual-2021-03-03) documents the Food Burn error (high temperature detected at the inner pot base, auto temperature reduction) and PrSE error (pressure accumulated during a non-pressure program). This is the manufacturer's own troubleshooting guidance for the Turkish market.
What to check. If 'Food Burn' appears, turn off the unit, release pressure, and check the inner pot base for starch deposits; clean the base before retrying. The manual says all other service must be done by an authorized representative.
Instant Pot Duo displays BURN error when liquid is too thick or insufficient
A UK Amazon review of the Duo 7-in-1 5.7L reports the BURN error appears when there is not enough liquid or the liquid is too thick, cancelling the cooking cycle. This matches the Turkish manual's Food Burn description and is a common owner-reported behaviour.
What to check. Follow recipes that specify minimum liquid volumes; if BURN appears, release pressure, add thin liquid, and restart. This is a usage-related error rather than a defect.
These reports come from the pages linked under each item: owner forums, repair guides and workshops. They are not a diagnosis of any one unit, and a careful check of the one you are buying still applies.
