During the wash cycle do you feel the dishwasher getting hot?
Are they dry at the end of the cycle?
Also as to the tablet once finished is the tablet laying on the bottom of the dishwasher or is it still in the dispenser but falls down when you open the door?
Ok what dissolves the tablet is hot water and the top spray arm spraying the water into the dispenser to dissovle the tablet.
What you need to do is open the dishwasher and turn the spray arm under the top basket so it faces front to back.
Set it going on a wash cycle and when you hear it washing slowly open the door and see if the top spray arm has moved position, Try it a few times and see what happens.
Also just check there isn't anything like a dishwasher air freshner hanging on the top basket just in front of the dispenser as this can cause this fault as well.
Check that and see what you find and let me know.
