The water tube valve is the clear tube with parts inside of it, and is connected to the bottom of the curved metal tube. Be sure to remove this tube and not the clear tube that is hollow, which is connected to the top of the metal tube.

Use pliers to pinch and remove the clamp holding the water tube valve onto the metal tube.

Rotate the metal tube to the right so it is perpendicular to the bottom of the coffee maker.

Use pliers to pinch and remove the second clamp attaching the water tube valve to the connection of the water dispenser.

Be sure to reattach the hose clamps when reassembling. This reduces the potential risk of leaks.
