The water supply to the top spray arm and the ceiling spray is brought through the inlet pipe attached to
the inside of the container rear wall. This pipe is connected to the pump cavity with a direct connection.
The water intake pipe has 2 separate water channels. This means that the top spray arm and the ceiling
spray can be separately activated.
When the top basket is pushed into the dishwasher, it engages onto the water intake pipe at the back to
make a water connection.
