The manifold distributes water from the central duct to the spray arms (the rotating wash or rinse arm) of the professional dishwasher or glasswasher.

Fixed basket central duct (mod. 11/F-FD Elettrobar): channels water from the pump to the spray arm. Complete wash/rinse spray arm (490mm length): the rotating arm ready to fit, as an alternative to replacing just the manifold.

For the spray arm shaft and bearings see Dishwasher Spray Arm Shaft; for other spare parts go back to Washing and Dishwashers.

Frequently asked questions

Do I need to replace the whole spray arm or just the manifold?
If the problem is only in the central water distribution, the manifold alone is often enough; if the arm itself is damaged, the complete spare part is the better choice.

Is washing uneven on some plates?
Check that the manifold isn't clogged with residue and that it distributes water evenly to all arms.
