In one paragraph
Washing-machine noise is mostly about balance and about what got into the drum. On a CBMmart washing machine levelling and transit bolts explain more of it than any component. That puts the machine is not level or its feet are not locked at the top of the list here and debris in the pump housing at the bottom.
How this presents
- Banging and walking during the spin — An unbalanced load, an unlevel machine, or transit bolts still fitted.
- A clicking as the drum turns slowly — Usually a small object caught in the drum holes.
- NEAR MISS — a hum with no drum movement — That is a drive or start fault, not a noise complaint.
Causes, most likely first on this unit
- The machine is not level or its feet are not locked — An unlevel machine walks, and a walking machine turns a small imbalance into a loud one. Imported machines are frequently self-installed, and a machine that was never levelled or was pushed back onto its own hose carries that fault forever.
- An unbalanced load — One heavy item, or a load wrapped into a rope, throws the drum off balance and the machine reports it by banging. Load habits drive most of the complaints on an imported machine: capacity is honest but it is not generous, and an overloaded drum produces symptoms that read as failures.
- Transit bolts still in place — On a newly delivered machine this is the first thing to check: the bolts lock the drum for shipping and must come out. How the unit was put in is part of the machine, and a bad install follows it for its whole life.
- Debris in the pump housing — A rattle limited to the drain stage, cleared from the filter hatch.
Check in this order, and why
- Ask whether the machine is newly installed — Transit bolts are the answer on a surprising share of new-machine noise calls.
- Rock the machine by its corners — Any movement means the feet need levelling and locking.
- Spin the empty drum by hand and listen — A scrape or a rumble with no load points at debris or a bearing.
- Note which stage the noise belongs to — Wash, drain and spin have separate candidate lists.
What an owner can safely do
- Level the machine and lock the feet — No rock at any corner, and the lock nuts tightened against the cabinet.
Tools: spanner, spirit level
- Redistribute the load and run a spin — A single heavy item on its own is the commonest banging complaint.
- STOP before opening the cabinet to reach the drum or bearings — The drum assembly is heavy and the cabinet is mains-wired.
Read this before touching the machine
Safety
A machine that walks can pull its own hoses off. Stop the spin, unplug it and level it before running anything else, and keep fingers out of the drum until it has fully stopped.
Where the owner side ends
Call when the machine is level, the load is balanced, the filter is clear and a rumble still grows with spin speed — that is bearings, and it is a workshop-scale repair. Call sooner if there is a scraping sound, because debris between drum and tub can perforate the drum.

Scope of this page
Generalized information: this describes the washing machine class, not your serial number. Anything tied to a chassis — pinouts, part numbers, diagnostic key sequences — is absent by design. A family- or model-level page, where one exists, is linked below and takes precedence. The brand overview page linked below covers the other problems on this machine.
