Question: Why is there still half a tablet left in the tub at the end of the wash?
This is not uncommon and depends on the type of tablet used. The latest 4in1 or 5in1 dishwasher tablets often leave residue, for instance. If you set a higher temperature (at least 60°C) then the tablets will dissolve better.
