A rattling washing machine is one of those problems that sounds minor but usually isn’t. The noise is telling you something — and the cause determines whether you can fix it yourself in ten minutes or whether you need a technician.
Here’s how to diagnose a rattling washing machine step by step, with callouts for Samsung, LG, Whirlpool, and Bosch units specifically.

Step 1: Check for loose items in the drum
Before assuming there’s a mechanical fault, check the obvious. Coins, buttons, bra underwires, and small items left in pockets are responsible for a large percentage of “mysterious” rattling noises. Check the drum, the door seal rubber, and the detergent drawer channel. A single coin wedged under the drum’s inner rim can sound alarming.
Step 2: Check if the machine is level
An unbalanced washing machine vibrates loudly during the spin cycle. This is especially common with front-loaders. Put a spirit level on top of the machine — front to back, and side to side. All four feet should be firmly on the floor.
Adjust the levelling feet by hand (most unscrew clockwise to lower). Lock them in place by tightening the locking nut against the body. If the feet spin freely or are corroded and won’t adjust, they can be replaced.
Step 3: Check if the load is balanced
An unbalanced load is the most common cause of banging and vibrating during the spin cycle. A single heavy item — a comforter, a pair of jeans, a wet towel — can cause the drum to spin lopsided.
Redistribute the load and run a short spin. If the noise disappears, the load was the issue. If you’re consistently getting this problem, avoid washing single heavy items alone — add a couple of towels to balance the load.
Step 4: Check the drum for play
Open the door and grab the drum with both hands. Gently try to move it up, down, and sideways. Some small amount of movement is normal. Significant looseness — more than a centimetre or two of travel in any direction — suggests worn drum bearings or a failing spider arm (the bracket that connects the drum to the rear bearing).
Worn drum bearings make a rumbling or grinding noise that gets louder during spin. If you hear that sound and feel drum play, the bearings need replacing. It’s a substantial job — several hours of labour — but usually cheaper than a new machine on a relatively recent washer.
Step 5: Check the shock absorbers and springs
The drum in a front-loader is held by suspension springs at the top and shock absorbers at the bottom. When these wear out, the drum can bang against the cabinet during spin — a loud, rhythmic thudding that’s hard to miss.
You can visually inspect the shocks by tilting the machine back carefully. If they’re leaking oil or obviously bent, they need replacing. Springs can break or lose tension — if one spring is longer than the other, or if a spring is disconnected, the drum will hang unevenly.
Brand-specific callouts
Samsung washing machine vibrating loudly
Samsung front-loaders (WF and WD series) are prone to vibration issues, partly due to how the drum is balanced from the factory. Samsung released a balance ring retrofit for some models. If yours is shaking excessively, check whether there’s an active recall or service bulletin for your model number. Also inspect the shipping bolts — if the machine was ever moved and the bolts were reinstalled but not removed before running, they’ll cause extreme vibration.
LG washing machine banging during spin
LG Direct Drive models (with the motor mounted directly to the drum, no belt) are quieter than most — so when they do rattle or bang, it usually points to a real issue. Common culprits on LG machines are the spider arm cracking (a known failure on older LG models), the bearing failing, or the stator on the direct drive motor getting damaged. These are repair jobs, not DIY fixes.
Whirlpool washing machine noise repair
Whirlpool top-loaders and front-loaders both develop drive pulley wear over time. A squealing or rattling during agitation (not just spin) often points to a worn drive belt or a failing motor coupler on top-load models. Both are inexpensive parts. The belt is usually visible by removing the back panel; the motor coupler requires taking the cabinet apart.
Bosch washing machine drum loose
Bosch front-loaders are generally reliable, but bearing failures do happen on older units (especially pre-2015 models). Bosch bearings are typically integrated into the rear drum assembly — unlike some brands where the bearing presses into the tub, on many Bosch machines the outer drum and bearing come as one unit. This makes bearing replacement more expensive on Bosch than on some other brands.
Noise during washing machine drum spin: is it the drum loose, or something else?
Not all rattling during spin means a loose drum. Here’s a quick guide:
- Rhythmic thud: unbalanced load, or worn shock absorbers
- Continuous rumble: bearing failure
- Metallic clank: foreign object in drum or pump
- Squealing: worn belt or pulley
- Random rattle: loose panel, coin in pump filter, or vibrating pipe
When to call a technician
Handle it yourself if the problem is: load balancing, levelling feet, or a coin in the drum. These require no tools and no parts.
Call a technician if: the drum has noticeable play, the noise is a continuous rumble, there’s a burning smell, the machine vibrates significantly even with a balanced load, or the noise started suddenly without explanation.
