The short answer
Most new noise on BFLW 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
- A buzz or whine only while water leaves — The drain pump under load. A change in its note usually means something has reached the impeller.
- The machine moves across the floor — On a light chassis this is the normal consequence of a foot not carrying weight.
- A grinding or scraping that follows the drum — Something hard between the drum and the tub, or caught in the pump.
- A squeal that rises with drum speed — A belt or a bearing, where the model uses a belt.
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.
- 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.
- Loose panels, lid, hoses or trim — Anything not fastened will chatter once the spin starts. It is worth a hand over the cabinet, because it explains a real share of noise complaints on a light shell.
- 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.
Check in this order
- 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.
- 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.
- Note which part of the cycle is noisy - fill, wash, drain or spin — Each belongs to a different part of the machine, so this one observation removes most of the list before you touch anything.
- 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.
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. Turn the water off at the taps before pulling the machine out, and be ready for the drain hose to give up what is still in it.
