OK, thanks for that.
Try going into diagnostics and out again.
This can sometimes reset the board and get it working again.
Turn the machine off.
Press and hold together the start button and the button to the left of it.
While holding them, turn the dial 1 click clockwise to turn it on.
The lights flash, release the buttons and the lights scroll.
If you get them scrolling, turn the dial clockwise through each position to off.
Then, turn to any program and back to off.
Now try the machine again.
If all is well, it should be working again.
Try it out, let me know how it goes and get back to me if you need more help.
Hope this helps
