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
