Appliances rely on precision components to operate smoothly, and springs play a critical role in everything from door mechanisms and latches to control systems and vibration management. At Southern Precision Spring, we manufacture high-quality, tight-tolerance springs designed to deliver reliable performance and long service life in demanding appliance applications.
Our commitment to precision manufacturing and consistent quality ensures that every spring we produce helps appliance manufacturers build products their customers can depend on.
Extension Springs in Washing Machines
Extension springs in washers are usually part of the suspension and balance system — they help control tub movement and absorb shock.
Common locations include:
-
Suspension System (Top-Load Washers):
-
Connected between the wash tub frame and the washer cabinet/chassis
-
Helps stabilize the tub during spin and agitation
-
Usually found in pairs or sets on opposite sides of tub
-
Door or Lid Assist (Some Models):
-
Small extension springs on lid hinges to balance and smooth opening/closing
Why they’re there:
-
Control vibration
-
Manage tub bounce
-
Support dynamic loads during spin cycles
Extension Springs in Dishwashers
Dishwashers use springs primarily to help raise and lower the door smoothly, rather than suspension of internal parts.
Typical locations:
-
Door Balance / Assist Springs:
-
Attached near the lower front corners of the dishwasher
-
Usually on torsion arms or pulleys, but if an extension spring design is used, it’s between the door arm and a fixed bracket
-
Helps counterbalance the heavy door so it doesn’t slam down
