To rectify this you need to reset the circuit board by using the following sequence:
-turn machine power off using the on/off switch
-turn machine power back on using the on/off switch..then press the function button 4 times within 3 seconds.
-if successfull this should light the outside 2 lights (lights 1 & 5)
-press the function button once more and turn machine power off again using the on/off switch....leave for 20 sec.
-turn power back on and settings should be back to normal.
Hope it works
