Commercial Dishwasher Wash Arms

Spray arms are critical components in commercial dishwashers, responsible for distributing high-pressure water throughout the wash chamber. Positioned at the top, bottom, or both, these rotating arms ensure even water coverage, effectively removing food debris and ensuring thorough cleaning in high-demand kitchen environments.

Dishwasher spray arms operate by spinning and spraying jets of water during the wash and rinse cycles. They are typically made of stainless steel or durable plastic and feature strategically placed nozzles or holes to maximize spray reach. Common signs of spray arm issues include unclean dishes, blocked nozzles, poor water flow, or arms not spinning freely. This is often caused by food particles clogging the holes, cracked arms, or mineral buildup. Regular cleaning and prompt replacement of worn arms are key to maintaining optimal wash performance.

At PartsFe CA, we offer a wide range of dishwasher upper spray arms, including Arm hold open retrofit assemblies, rinse arm shafts, basket lift arms from top brands Frymasters, Robot Coupe, Taylor Freezer and more.
