I have just aquired a Bosch D/W and need a bit of input. Model Number is shu33a02uc and I am trying to install it but was stumped when I saw 2 hoses. I know One (grey) is the drain bt I am stumped seing a shite hose as well. Can anyone help. I know that this is not the water input since it is a NPT adapter in the front. Thanks for all that help.
