The thing MUST have the salt in there in order to work! Salt IS an impurity, too. And yes, any and all impurities will built up as a crust on the electrodes.
So again, why would one use distilled water -- and then add an impurity? (Which will build up inside the plates.) The only reason I can think of is to try and control the rate of conductance -- though he sure doesn't measure it, like he said in the instructions...
