tablet draw is a seperate issue and may need replacing although putting the tablet on the silver filter bit will do the job nicely.if the wash result is ok and the holes in the top spray arm are clean then may be the magnet in the top arm is faulty.this will require you to purchase a new top spray arm as it counts the rotations of the top arm and if it is slow gives alarm code.just check filters are clean as well
