Ive been using liquid Tide since getting my A407 a few years ago as Its been cheap at $9.00 a bottle and I like the smell. I just bought the same sized bottle of Persil ($16.99!!) so we'll see how that does. My issue is I have to use very little detergent or the machine suds locks in the rinse spin. Im hoping Persil is better for that but Ive also heard powdered detergent doesnt suds as bad?? If so should I switch to powdered Tide? Im not sure if the long travel or height of the stand pipe is whats doing it.
