does the water drain perfectly fine at the end of the cycle and this water appears after a while?
Or is it left at the end of the cycle?
Are you there?
i have run the dishwasher a nu,ber of times now and the water is present immediately after the cycle is finished.
That means it's not draining fully, this is a software problem with the unit
If it's not a major issue with the cycle (meaning dishes come clean) I would wait until there is something else that goes wrong before changing the board
There could be more issues, it may do this for years with no new issues
