Upper spray-arm manifold, a replacement part for ATA professional dishwashers, compatible with models AF61, AF610, AF88 and AF78.

The manifold is the central component that the upper spray arm attaches to: it receives pressurised water from the wash circuit and directs it to the holes of the rotating arm, while also allowing the arm to spin freely during the wash and rinse cycle. A worn manifold, or one with cracks or damaged seals, causes water leaks, a pressure drop at the jets and poor washing performance, or can block the rotation of the upper arm.

Replace it when the upper spray arm no longer spins correctly, when water leaks appear around the manifold, or when washing in the upper part of the tank becomes insufficient.
