On the back. You will see the black flexable line. It's about a 1-1/4'; line.On a kenmore washing machine, where is the drain pipe? Like if u want to change / clean it?
There is a drain ';hose'; but not a ';pipe';. It's the black hose with a ';U'; shaped end on it. The drain hose runs from the lower back of the machine and upwards to the house drain that is behind the washer.
