Error code

[banc123]

Range is only a couple years old and I was trying to change the time which was set up to only use WiFi , so I was pressing buttons trying to do it manually and it started showing this code and will no longer work on eyes or oven.  

code is 4 lit up “de”

Error code DE is normally for a stuck button or the over partition isn't fully in place 

But since you said you were pressing buttons and then the code showed up I'm thinking a button is stuck

The buttons I was pressing are the ones that are touch screen and don’t stick out.   Maybe I pushed one too hard 🤔
