Why is the quick connect leaking on my Karcher electric pressure washer?

The quick connect adapter on Karcher K2, K3, K4 and K5 electric pressure washers (as well as some other Karcher electric pressure washers) will leak if it is not correctly attached. The correct way is to attach the yellow side of the adapter to your garden hose and the black side of the adapter to your pressure washer. Please see the illustration below. Note that even though you can attach the adapters in reverse, they will leak/spray water due to the different size threads in each side of the adapter.
