Understanding the Role of the Lower Spray Arm in Your Dishwasher
What Is the Lower Spray Arm?
The lower spray arm is a crucial component of your dishwasher's cleaning system. Located at the bottom of the dishwasher tub, it rotates during the wash cycle, spraying water and detergent onto the dishes to loosen and remove food residues. The spray arm is typically made of durable plastic or metal with multiple small nozzles or holes that distribute water in a wide pattern. Proper operation of the lower spray arm ensures thorough cleaning, especially for pots, pans, and heavily soiled items placed on the bottom rack.
Common Problems with the Lower Spray Arm
Over time, the lower spray arm may encounter issues that impair its function. These include:
- Clogging: Mineral deposits, food debris, or broken pieces can block nozzles, reducing water flow.
- Cracks or Breakage: Physical damage from impact or wear can cause the spray arm to crack or break, leading to leaks or uneven spray patterns.
- Loose Fitting: The spray arm may become loose or detached, affecting water distribution.
- Corrosion or Wear: Exposure to water and cleaning agents can cause deterioration over time.
Recognizing these problems early can help you determine whether a replacement is necessary.
