Here you see the water intake hose, sucking water from out of the water tank and delivering it to the water pump.

The hose connects to the pump at its bottom side, so you can't quite see it.

The hose is secured to a black plastic piece in the bottom of the case by a metal clip that can be loosened with pliers.

Take off the hose and be careful not to lose the metal clip!

You can't take off both endings yet as the end that goes into the pump is still hidden!
