Dishlex global 300. ECO light flashing.

Question

i set the dishwasher as normal (on super). i went back to check a little later and the ECO light was flashing. the machine was making a humming noise as it does when it is operational, however it wasnt operating. i tried switching off at the wall and then back on but it does the same thing. tried pushing the start/pause and the programme buttons simultaneously but nothing changed.
when i opened the door there was no water in there (luckily...) but there were soap suds in the bottom of the dishwasher.
