I have just had this happen to my oven and so took awhile to figure it out, so simple if I hadn't misplaced my manuals and had to second guess.
There are 5 buttons :-
1 - Bell
2 - Vertical heat waves
3 - Vertical heat waves over cooking pot
4 - Hand
5 - Arrows facing left and right
Press no 2 button in and hold, turn no 4 button and this will turn the oven off from auto.
Use these two buttons to turn the oven on and off from auto.
