Read this before buying this specific model of the Instant Pot. This is an issue that can greatly reduce your enjoyment of this otherwise wonderful product.
I bought the Instant Pot Duo Evo Plus 9-in-1 on Jan 6, 2020. I've used the pot six times so far and whenever I'm sautéing, I frequently get Error Code C8 (wrong pot) even thought I'm using the pot with the easy grip handles that came with it, and I alway make sure that the pot is clean and seated properly before I use it.
When I reported this issue to Instant Pot Customer Service, here’s the response that I received.
“This error often occurs due to excess movement of the inner pot when stirring. We recommend gripping the inner pot firmly when stirring.”
Instant Pot's User Manual states that the Easy Grip Silicone Handles hold the inner pot in place while cooking, and in no way am I doing anything that would cause what Instant Pot describes as “excess movement of the inner pot”!
Their response goes on to say, “We have done some testing on the Duo Evo Plus, and have found that the C8 error can be fixed. All you would have to do is unplug the unit for 30- 60 mins in order for the Instant Pot to cool. Once you plug it back in the error code will have cleared.”
Apparently Instant Pot's solution to this “excessive movement” problem is to be very careful not to move the inner pot too much while stirring and if this “wrong pot” error occurs, unplug the unit in the middle of preparing your meal and wait 1/2 hour to 1 hour before resuming your meal preparation. This seems to take the “Instant” out of the Instant Pot?
If this recommended solution wasn’t so sad, it would be laughable. If there is a design defect in the Duo Evo Plus 9-in-1, Instant Pot should own up to it and warn their customers.
This is very unfortunate as this is an otherwise well designed product.
