Unfortunately I have a “fancy faucet” with a flush aerator which will not properly attach the Unicouple. Despite the Instruction manual indicating that any hardware or plumbing supply would have a part... I’ve been to 6 places, tried as many parts and still have an unusable dishwasher. 
I hope I don’t have to replace my faucet, will keep looking for an adapter, but it shouldn’t have to be that hard. Pretty frustrated and bummed at this point. A week in and still can’t use the darn thing.
