The short answer
On the ATW models this complaint is most often a machine that is not standing level rather than anything deeper. This line is a close pair of models rather than a spread, so the build is effectively uniform and the seal-and-fit causes come forward. The order below is settled by how this line is built, not by what is true of the brand as a whole.
What you observe
- A grinding or rumbling that rises with drum speed — Continuous rather than rhythmic, and it gets louder as the spin builds.
- A rattle or clatter during drain only — Tied to one part of the cycle, which places it at the pump.
- NEAR MISS — the noise comes with water on the floor — Then the leak is the fault to read about first, and the noise is a symptom.
Causes, most likely first on the ATW line
- A machine that is not standing level — Ranked first here — it costs nothing to rule out and it makes every other noise on this list louder.
- A coin, a stud or an underwire loose in the machine — Second here — it is the most common find of the list and because the longer it runs the more it costs to put right.
- A load that will not distribute — Third here — it is temporary and confirming it saves a call that was never needed.
- Body: Two closely related models means what holds for one holds for the other, which is why the order below is stated without a hedge. Against a ranking that ignored how these are built, a machine moves up and a coin, a stud or an underwire loose in the machine moves down — that is the whole departure.
Check in this order, and why
- Push each top corner down in turn and watch for movement — Any rock at all means one foot is short, and that is enough to turn a spin into a walk.
- Open the pump filter and empty it into your hand — Hardware in the filter is the answer. Hardware that is not in the filter is still in the machine, between the drum and the tub.
- Open the machine mid-spin and look at how the load is sitting — A single towel or a duvet wound into one mass will not balance, however good the machine is.
- Body: Two closely related models share a layout, so a check that works on one works on the other and the order below does not change between them. Each check answers the cause above it, in the same order, so a clean result moves you down the list rather than sideways.
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. Shut both taps before opening the pump filter, put a shallow tray and towels down first, and expect water. A washing machine is heavy and top-loaded with a concrete counterweight: never tip one onto its back to look underneath, and never run it with a panel off.

When to call a technician
Call when the noise rises with drum speed and you can feel grit through the drum by hand, when the machine walks despite being level and loaded properly, or when a burning smell comes with the noise. Stop the machine and call at once if there is smoke, a scorched smell, or a breaker that trips when it spins. Of the causes listed above, most are owner checks and the last is not — that is the line.
