|If your Top Load Washing Machine Shakes or Vibrates Check The Following
First check the level of your machine. Check with a bubble level front to back and side to side. Now that you have it close check from one rear corner then diagonly to the opposite front corner. There should be no rocking. Now check the other corner to corner. Now that it is level make sure you tighten the locking nuts on each leveling leg. This is important it will keep your machine from needing to be releveled. Do not put machine on carpet this will cause the machine to be releveled when the carpet flattens out.
Next if your washer is leveled and sitting firmly. Access the drain pump and remove the hose to the tub. This hose will have a small amount of water use a wet vac to catch this as you remove the hose. Next remove the pump and check for obstructions. Check the impeller that it is not broken and spins freely. If all looks good there check the drain hoses for obstructions. Check that the pump is running.
Some washers(GE) use suspension rods that the tub hangs off of. These usually do not break. You will need to remove the front panel or cabinet to check these. The tub will hang off of the rods and have dampers at the ends. Check that the dampers are firmly attached and the tub hangs evenly.
Some washer use Snubber Blocks that help reduce vibration. These do wear out over time. Theere are usually 8 on your machine in each corner.
