CodeMeaning
5EThe control board detected a button signal that's been active for more than 30 seconds straight. That's its threshold for deciding something's stuck or shorted. Could be a physical key that won't spring back up, or two conductive layers inside the membrane film touching when they shouldn't be.

HUBSamsung microwave ovens display error codes including SE (stuck key), C-10 (communication fault on smart models), 5E (button stuck variant), and descriptive errors. Samsung microwaves use fewer codes than washers or dishwashers.

SEThe SE code (often read as 5E) indicates a 'Key Short' error. The control board senses that a button is being continuously pressed for more than 60 seconds, usually due to moisture or a physical failure in the touchpad.
