If your control panel looks like this, I pushed and held each button for 10 seconds starting with the top left and working to my right bottom. On mine it was the ‘End of Cycle Signal” button. How I did this was, to first unplug it for 5 min (didn’t work) Then, push a single button at 1 time for 10 seconds and hit the pink cancel button 1 time between each new button. until it works or if it hadn’t , My plan was to begin pushing 2 at a time in a logical order. It won’t let me post the pictures, sorry.
