WASHER COUNTIUE TO ADD WATER

If the unit seems to be overfilling and you have already replaced the pressure switch (water level switch) then all that would be left would be a hole in the air tube going to the pressure switch or a control board issue. If the unit is adding water when the unit is not running at all or unplugged then you have a sticking solenoid in the inlet vale. I would check the air tube very well (especially any points of contact with the outer tub or around zip ties for small holes in the tube). If no holes are found in the air tube then the control board is most likely the problem.
