The short answer
Most new noise on MAR models is the machine walking, an object loose in the drum or in the pump, or a load that has gathered on one side. All three are owner-findable, and all three come before the tub bearing that the generic article puts first.
What you observe
- Loud only during the spin — Balance, footing or something loose. The spin is the only part of the cycle with enough energy to make the rest audible.
- The machine moves across the floor — On a light chassis this is the normal consequence of a foot not carrying weight.
- A squeal that rises with drum speed — A belt or a bearing, where the model uses a belt.
- A rhythmic thump at low speed — A load gathered on one side. It is the machine telling you it could not redistribute, not that a part has failed.
Causes, most likely first
- The machine out of level or standing on a floor that gives — First on this family. A light chassis has nothing to damp a spin that is even slightly out of true, so one foot off the floor turns an ordinary load into a machine that walks and drums.
- Transit or shipping restraints still fitted, or feet not set — A genuine cause on a platform light enough to be moved and re-sited by the owner. A machine that has never been quiet since it was installed is usually this rather than a fault.
- A load gathered on one side — Second. A small drum concentrates an unbalanced load far more than a large one, so a single heavy item or a sheet that has wrapped will produce a thump the whole house hears without anything being wrong with the machine.
- Debris at the drain pump impeller — The pump sits low and takes everything the drum lets go. A hair pin or a fragment of a garment against the impeller gives a grind or a buzz only while the machine is draining.
Check in this order
- Turn the drum by hand, slowly, listening for a scrape — Finds a foreign object between drum and tub without any tool, and it should be done before running anything else.
- Check every foot is carrying weight, with a level across the top — Second because it is free and because it is the leading cause on this family.
- Confirm any transit restraint has been removed and stored — Last of the free checks, and the first one worth doing on a machine that has never been quiet.
- Open the pump filter or access flap and look at what is in it — Worth doing while the machine is off anyway, because debris here explains a noise heard only during draining.
Before you open anything
Safety
Unplug the appliance or switch off its breaker before removing any panel. A capacitor can hold a charge after the power is off. A compact washer full of wet laundry is much heavier than an empty one - drain and empty it before moving it, and keep it upright.
