miele w360 wps washing machine light are on but programs aren't?

Hi
I washed something that was apparently too big and ended up water logged. The program stopped but the light are on not blinking. The display for the program timing is dark and I had to open the door manually.
I have tried to press different buttons' combinations. The only one that creates a reaction is when the machine is off set on Finish and I press together the Start+Delay+any other button and then turn the machine back on. The display flashes back and forth "Err" then "Cal." I have also cleaned the filter and let the water drained. I even tilted the machine to get more water out and let it dry overnight?
Any suggestion as to what to do to reset it?
Do I need to do something with the leak tray? Where is it?
Thanks
