Like any household appliance, the dishwasher requires regular maintenance to maintain its performance. To ensure the proper functioning of a dishwasher, it is important to maintain its spray arms.
A dishwasher has two wash arms or cycle arms. These two arms are supplied with pressurized water. The role of these two elements is to propel the water on the dishes in order to clean them.
- The lower arm is fed by a water hose to allow the washing of dishes and plates.
- The upper arm is fixed under the basket of the dishwasher, is supplied by a small water hose and which offers a lower pressure, it makes it possible to wash the most fragile elements which are in the upper basket.
Regularly clean the cycling arms, and replace them if worn, replace them:
- Better watering of the dishes during the cycle
- Better rotation of the wash arm
- Better circulation of water in the circuit
- A decrease in electricity consumption
- A reduction in the consumption of detergent product
The washing arms in a dishwasher are responsible for spraying water and detergent onto your dishes, ensuring thorough cleaning. Over time, the washing arms can become clogged with debris, mineral deposits, or food particles, resulting in reduced cleaning performance. Regular cleaning and occasional replacement of the washing arms are necessary to maintain optimal dishwasher functionality. In this article, we will guide you through the process of cleaning and replacing the washing arms of a dishwasher.
