Fagor Dishwasher LFU-45IT Program Lights All On

I have got an annoying intermittent fault with my Fagor dishwasher.
Turn it on, and all program lights, light up. The program button when pressed does nothing.
If I come back to it, say a few hours later, it might work normally.

Water pressure seems fine, and its been cleaned, no blockages as far as I can tell.

If the fault does clear, then I power off, and power on again, it does the same as before.
Is there some secret Fagor key press sequence to clear the display? It only has two buttons (Program and start)
