Why a banging washer happens#
Nine times out of ten a washer making a banging noise traces back to failed shock absorbers — blown shock absorbers let the wash tub slam its cabinet on spin. The next suspect to rule out is foreign object in drum; the ranked table below shows where to look first and roughly what a fix runs. Catch which part of the cycle the sound rides on and you are halfway to the answer. The reassuring part is that most of these come down to one worn part, not a machine that is finished.
What a banging really means, ranked by odds#
A washer banging is a noise whose exact pitch and timing point toward the failing part. You will usually catch the banging during the high-speed spin, when the drum is turning fastest.
| Likely cause | What's happening | How likely | First thing to check | Fix it yourself? |
|---|---|---|---|---|
| Failed shock absorbers | blown shock absorbers let the wash tub slam its cabinet on spin | Most likely | push the tub down and see if it springs back slowly | No — pro repair |
| Foreign object in drum | a coin, wire or clip is trapped and tumbling inside the drum | Possible | check the drum, gasket and pump filter for stray items | Yes — often DIY |
| Loose drum spider | the cast drum spider arm has corroded and cracked, unbalancing the tub | Less likely | rock the drum and watch for play at the rear hub | No — pro repair |
Typical repair cost: $150–450, depending on which part has failed.

Safe checks, then the cost call#
Before any hands-on look, switch off the power at the breaker and let it come to rest. Take it in order and note what changes as you go. With that done, push the tub down and see if it springs back slowly. After that, check the drum, gasket and pump filter for stray items. It is also worth a moment to rock the drum and watch for play at the rear hub. Pay attention to when the sound rises and falls; a note that tracks the drum or the fill usually fingers the loose part on its own. Once the shock absorbers is on the table, put the tools down; that repair belongs with a technician, not another test run. Once the part is confirmed, most of these repairs sit in the $150–450 range, and that is usually money well spent on a washer with plenty of service left in it.
Common questions when the banging starts#
Why is my washer making a banging noise?#
The usual answer is the shock absorbers, with the foreign object the next most common. Both are quick to narrow down using the ranked table above. A short look normally tells you which one you are dealing with.
Could failed shock absorbers be the cause of the banging?#
It can be. The shock absorbers is one of the top causes here, so check it early before moving on. If it comes up clean, the next candidate is right behind it.
Does foreign object in drum also make a washer banging?#
Yes — the foreign object is a real suspect for this exact symptom and sits high on the list. Rule it out first, then work down to the next cause. A quick look usually tells you whether you have found it.
What about loose drum spider — can that do it?#
Most often it is the shock absorbers, and failing that the foreign object. The table above puts the causes in order of likelihood so you check the smart one first. From there it is fast elimination.
Is the banging dangerous?#
A single off note is low risk on its own, but a straining motor or metal grinding on metal should not be left to run. Switch the washer off once you have spotted the trouble and have it looked at before the next load. Catching it early is what keeps a cheap fix from becoming an expensive one.
