The Frigidaire 154724001 Lower Wash Arm Support provides stable positioning for the dishwasher’s lower wash arm during cleaning cycles. This replacement component supports the wash arm assembly and allows it to remain properly aligned while water is distributed throughout the dishwasher. It works with the lower spray system to maintain the correct position for water circulation and effective coverage of dishes. A worn, damaged, or broken support can affect wash arm stability and interfere with normal operation.
