confirmed: all detergent in California now phosphate-free
Evidently California didn't change its laws, but with other states now banning phosphates, the manufacturers are aiming for simplification, i.e. production of only one version of each product. I have about 500 Finish tabs hoarded away, partly because I bought 4-5 Finish canisters (80 tabs each) at Costco a few years ago when I heard the phosphate ban was coming, and then I received two similar canisters (so old they say Electrasol, not Finish) from friends who could not close the dispenser door of their KA over the tabs and wanted to find them a good home (they use powder to fit the KA dispenser).
The person who told me this is the owner of our local appliance store. He stated his customers still get good results with higher end units (KA, Bosch, etc.) and no-phosphate detergents, but the key is the prime the hot water line before starting the machine, to be sure the first rinse (which is not heated by the DW) is as hot as possible. For most applications, this would mean running the hot water kitchen tap until the temp reaches full hot water line temperature.
