F2 relates to a blocked drain pipe or pump.
Remove the grate at the bottom of the dishwasher and give the filter a clean, and make sure nothing is blocking the sump.
Next check the waste pipe from the washer going into the sink hasn't become blocked, and the drain its connected to hasn't backed up.
Once checked switch the appliance back on and run an economy or rinse cycle and see if you get the same fault.
