Washing machine springs control the forces generated during high-speed spin cycles. For engineers involved in creating or repairing home appliances, it is advantageous to understand these springs - their characteristics, location, replacement, and how to choose the correct type. Poorly installed or incorrect springs could lead to a detached drum, emphasizing the necessity of this information. There are differences between compression and extension springs that affect the choice of which to use. Ready yourself to explore these elements and more in this guide to washing machine springs.

Requirements for Washing Machine Springs

Washing machine springs require specific characteristics to handle the demands of varied laundry-related tasks. For instance, the springs must have the ability to withstand the weight of items like heavy blankets or winter coats that families prefer to wash regularly. The springs should be durable and constructed from materials that resist deterioration caused by water, detergents, and heat – usually, stainless steel is used for this purpose.

The design of the spring impacts the performance of the washing machine. A key characteristic of these designs emphasizes torsional strength. Springs equipped with the right level of torsional strength stabilize the washing machine during rotations, avoiding bending or distortion of the spring. In contrast, a spring lacking the necessary torsional strength can lead to imbalance during spinning, resulting in unwanted noise, increased vibration, and the potential for damage.

The dimensions and load capacity of the spring should align with the specifications of the washing machine. An oversized spring used in a compact washing machine may restrict the movement of the washing machine's tub due to flexibility issues, affecting the overall performance. On the other hand, choosing a spring too small can lead to excessive vibrations and noise. Therefore, selecting a spring with the right size and load capacity is crucial for the optimal performance and life span of the machine.

Lastly, the spring design should allow for easy and safe replacement to simplify maintenance tasks. A thoughtfully designed spring aids in smooth and risk-free replacement, avoiding any negative impact on the other components of the washing machine during the component replacement process.

How to Replace Washing Machine Springs

The disconnection of the washing machine from the power source is an initial safety measure when replacing its springs. Precisely matching the replacement spring to the model of your washing machine is crucial to prevent issues related to incompatibility.

Starting with the removal of the washing machine's cabinet, this typically requires the loosening and removal of several bolts on the machine's rear. Accessibility to the springs is possible once the cabinet is taken away. A pair of locking pliers can detach the old spring. Memorizing the position and orientation of the original spring is necessary for the installation of the new one.

Before the installation, the new spring should be compared to the old one. A discrepancy in the number of turns could result in future mechanical issues. Secure the new spring using pliers in exactly the same position and orientation as the old spring to ensure proper functioning. Proper positioning of the spring assists in control of the machine's vibrations.

Post replacement of the required springs and reattachment of the cabinet, operate a test wash using a small amount of laundry to verify the machine's performance and stability. Successful completion of this test signifies the machine is prepared for regular operation.


Springs in washing machines are essential for the machine's operation. This article has provided guidance to engineers on optimizing their spring design and selection process for washing machines. It highlighted the different types of springs, their properties, and how these properties affect the machine's function. With this knowledge, engineers can make better decisions. Selection of suitable springs, considering the machine's load and vibration needs, can help in mitigating machine breakdowns and reducing the frequency of spring replacements.
