Washing Machine Shaking or vibrating excessively

Excessive shaking or vibrating during a wash cycle is one of the most common washing machine problems, and in most cases you can fix it yourself without any special tools. The cause is usually something simple like an uneven floor, an unbalanced load, or worn leveling feet — all beginner-friendly fixes. This guide will walk you through each possible cause in order from easiest to most involved, so you can find and solve the problem quickly.

1. 1

   Step 1: Unplug the Washing Machine

   Before you do anything else, pull the washing machine's power cord out of the wall outlet. Even if you are only planning to check the leveling feet or move the machine, unplugging it prevents any accidental start-ups while your hands are near moving parts or underneath the appliance.

   Step 2: Check and Redistribute the Laundry Load

   Open the lid or door and look at how the clothes are arranged inside the drum. A single heavy item like a comforter, jeans, or a large towel can bunch up on one side and throw the drum completely off balance. Pull everything out, shake each item loose, and reload the drum by spreading clothes evenly around the inside. Avoid washing one very heavy item alone — add a few similar-weight items to balance it out. Close the door, plug the machine back in, and run a spin cycle to see if the shaking is gone.

   Step 3: Inspect the Floor Surface

   The floor under your washing machine must be solid and level. Tile, concrete, and hardwood floors are ideal. A soft or slightly springy floor — such as a weak wooden subfloor or a thick rubber mat — can allow the machine to bounce and amplify vibration. Try rocking the machine gently by hand on all four corners to feel if the floor itself has any flex. If the floor feels soft or bouncy, place a 3/4-inch thick piece of plywood (at least as large as the machine's footprint) underneath the machine to create a firm, even surface.

   Step 4: Level the Machine Using the Adjustable Feet

   All washing machines have adjustable leveling feet — usually two in the front and two in the back. Unplug the machine again. Place a bubble level on top of the machine and check it side-to-side and front-to-back. If the bubble is not centered, the machine is not level. To adjust the front feet, tilt the machine back slightly (get a helper if needed) and turn the front feet by hand or with pliers — turn clockwise to lower that corner, counterclockwise to raise it. Many rear feet are self-adjusting: tilt the machine forward about 4 inches off the ground, then set it back down — the rear feet should lock into a level position automatically. Recheck with the level and adjust until all four corners sit flat.

   Step 5: Tighten the Locking Nuts on the Leveling Feet

   Once each foot is at the right height, there is a locking nut just above each foot that needs to be tightened against the machine's base. This nut prevents the foot from turning and losing its adjustment during operation. Use an adjustable wrench or pliers to snug each lock nut up firmly against the bottom of the machine frame. Do not overtighten — just snug is enough. Recheck the level one more time after tightening, since tightening the nut can sometimes shift the foot slightly.

   Step 6: Check That Shipping Bolts Have Been Removed

   If your machine is newly installed or was recently moved, check whether the shipping bolts or shipping rods are still in place. These are large metal bolts — usually 3 to 4 of them — inserted through the back of the machine to lock the drum in place during transport. If they are still installed, they will cause severe banging and vibration the moment the machine starts spinning. Look at the back panel of the machine for plastic-capped bolts in a row. If you find them, unscrew and remove each one, and save them in case you ever move the machine again. Plug holes are usually supplied with the machine to cover the openings.

   Step 7: Inspect the Suspension Springs or Shock Absorbers

   If the steps above did not solve the problem, the internal suspension system may be worn out. Top-loading machines use suspension springs (sometimes called balance springs or snubber springs) that hang the drum from the outer tub frame. Front-loaders use shock absorbers (similar to car shocks) to dampen drum movement. Unplug the machine. On a top-loader, remove the cabinet panels or lift the top to see the drum suspension. Look for any spring that is stretched out, disconnected, or broken. On a front-loader, remove the front panel to find the shock absorbers at the bottom of the drum and check for oil leaks, cracks, or loose mounting points. A faulty spring or shock needs to be replaced.

   Step 8: Check the Drum Bearings

   If the machine vibrates heavily AND makes a loud grinding or roaring noise during the spin cycle, the drum bearings may be worn out. To test this, open the door and try to wiggle the drum up and down by hand with the machine unplugged. If you feel noticeable play or hear a grinding sound when you turn the drum by hand, the bearings are likely the cause. Bearing replacement is a more advanced repair that often involves partial disassembly of the machine. If you are not comfortable with this level of repair, consider calling a professional technician at this stage.

   Step 9: Reassemble, Plug In, and Run a Test Cycle

   Once you have completed whichever repairs were needed, reinstall any panels you removed and make sure all screws are tightened. Plug the machine back in. Load a small, balanced load of laundry — a mix of similar-weight items works best for a test. Select a cycle that includes a full spin and let it run completely. Stand nearby and observe the machine during the spin cycle. The machine should move no more than an inch in any direction. If the shaking is dramatically reduced or gone entirely, the repair was successful. If severe shaking continues, revisit the earlier steps or consult a professional.
