What it means

Err can follow opening the door before a sensor program detects steam, or no steam being detected within the maximum time.

This explanation is shared only by models whose manufacturer documents the same code, meaning, and guidance.

For an early door opening, close the door, press CLEAR/OFF and start the program again.
Let the sensor run until steam is sensed and a countdown appears.
If food needs more heat afterward, use Time Cook.
