Heres the instruction for a reset, i beloive you have completed part of the process.

1. Bail out all the water from the inside
2. Remove the filter and 2 x mesh pieces.
3. Continue to bail out the water from the filter well.
4. You will probably find pieces of food or fat/debris in the bottom of the well. Remove these.
5. Tilt back the dishwasher at 45 degrees for 30 mins or so to drain and dry the flood sensor.
6. Boil a kettle and pour it down the well. Immediately put the dish washer on a eco wash (no tablets or anything) with half load (ie half water) and this will ease the water pump.
7. Let the dishwasher run its cycle.
8. Clean the filter again and the filter well
