If your Gibson washer won't agitate, the agitator repair kit is the most likely cause. Worn, stripped, or damaged agitator components can prevent the agitator from moving even when the washer motor runs. Next, inspect the drive block or bell, which connects the transmission shaft to the agitator. A damaged drive block may allow the shaft to move back and forth while the agitator moves only slightly or not at all. A failed lid switch assembly can also cause a washer not agitating, since many top-load models will not agitate or spin unless the lid switch detects a closed lid. Make sure the lid is fully closed and that nothing blocks the lid strike from engaging the switch or latch. If those parts check out, inspect the motor coupling for breakage caused by overloading or normal wear, then check the drive belt for looseness or damage. These are common causes of a washing machine not agitating, including a washer that won't agitate but will spin. Enter your model number to find the exact replacement agitator repair kit, drive block, lid switch, motor coupling, or drive belt for your Gibson washing machine.

The drive block connects the washer transmission to the agitator. If the drive block is worn out, the transmission shaft will still move back and forth, but the agitator will only move slightly or will not move at all. Inspect the drive block for damage. If the drive block is worn out, stripped, or damaged, replace it.
On some models the lid switch assembly prevents the washer from both spinning and agitating when the lid is open. If the lid switch assembly fails, the washer will not spin or agitate. To determine if the lid switch assembly is defective, use a multimeter to test the lid switch for continuity. If the lid switch does not have continuity when the lid is closed, replace it.
On most top load machines the washer will not agitate or spin without the lid being fully closed. Close the lid after loading the washer and ensure there are no obstructions preventing the lid strike from connecting to the lid switch or latch.

05 - Gibson Washing Machine Motor Coupling
The motor coupling connects the motor to the washer transmission. If the washer is overloaded, the motor coupling will fail in order to protect both the motor and transmission. The motor coupling can also fail due to normal wear. Inspect the motor coupling to determine if it is broken. If the motor coupling is broken, replace it.
