Instant Pot over-pressure condition
This video shows a defect that developed about a month after I purchased my 8 qt. Instant Pot DUO. This shows an over-pressure failure that's occurring during the "water test".
I started the test with 2 cups of water, Steam Mode, High Pressure, for 3 minutes. When the pot creates enough steam pressure the float valve closes, and the pot starts coming to pressure. Eventually the working pressure is reached and the display switches from "On" to "3".
At this point a video timer shows that less than 30 seconds later the pressure has continued to increase more than it should until the pressure release safety valve is tripped and steam starts escaping from the Pressure Release knob. This video shows a failure in the Pressure Sensor that is not telling the Instant Pot computer to turn off the heating coil and stop making steam.
