How can I fix my Miele C975 SC plus dishwasher? ?

My machine seems to carry on working when i close the door although the machine is at the stop position. The machine is turned on with the green light flashing with no programme set.
I did have the inlet/drain light flashing and have cleaned the filters including the non return valve and around the drain pump.
Where the drain pump is situated looking at the machine, (and thinking of a clock face) at 35mins to the hour there is a small recess. There was a small sliver looking bar approxiamtely 10-15mm long about 5mm in diameter, during cleaning I accidently pushed this and it receeded into a whole that I am unable to reach.
Water is getting into the machine as I have dried the machine out and placed it on a programme. The "propellers" are turning aswell.
It runs for approximatley 10 minutes and then the inlet/drain light flashes again.
I have cleaned the machine time and time again with boiling water
I have now resorted to praying, Please help!!!!!!!!!
