The short answer
A Costway XQB Washer that has started banging, grinding or squealing is describing one of four things: an unbalanced load, an object in the drum or pump, worn suspension, or a failing tub bearing. The first two cost nothing and the last is the one that decides whether the machine is worth keeping.
What you see on the XQB family
- Loud banging during the spin that settles when the load redistributes — An unbalanced load, which is the single most common washer noise and not a fault at all.
- The machine walks across the floor during the spin — Feet out of adjustment, a flexing floor, or transit bolts never removed on a machine that has been moved.
- A grinding or rattling noise at the drain step only — Something in the pump — a coin, a button, a scrap of underwire working against the impeller.
- A rumble that rises with spin speed and never settles — The tub bearing. It grows over months and it is the noise that decides the economics of the machine.
Causes, most likely first on the XQB family
- Suspension, dampers or transit bolts — Ranked first on the XQB family — where the machine has been moved recently, transit bolts are the first thing to check and the fix is free. The tub hangs on springs and dampers that wear, so the assembly swings further than it should. A machine that has been moved and still has its transit bolts fitted behaves exactly the same way and is not damaged yet.
- Unbalanced load and levelling — Second — always near the top: it costs nothing to test and it explains most spin-step banging. A single heavy item, or a load that has migrated to one side, makes the tub orbit rather than spin.
- Foreign objects in the drum, the pump or the tub gap — Third — and free to check through the pump filter where one is fitted. Coins and buttons pass the drum and land in the pump or between the drum and the outer tub.
- Tub bearing or the drive belt — Fourth — and the most consequential: a bearing replacement on a machine of this class is usually weighed against replacement. A failing tub bearing rumbles and grows louder with spin speed, and it does not come and go with the load.
- Body: With only 5 codes in the XQB family the ranking below is taken over a short roster rather than over everything the brand sells, which is why the top of this list is not where the brand-generic article puts it.
Check in this order, and why
- 1. Stop the machine and redistribute the load by hand — Spread it evenly around the drum and restart the spin. If the noise goes, it was balance and nothing is wrong.
- 2. Confirm transit bolts were removed if the machine has been moved — They are at the back and they are meant to come out before first use; left in, they make a machine bang alarmingly.
- 3. Check the machine is level and all feet are firm — Rock each corner. A machine on three feet converts ordinary spin forces into banging.
- Body: The 5 codes in the XQB family are close enough in layout that the order below holds across all of them; check the plate on your own unit against the table before you order anything.
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. Never reach into a drum that is still turning and never hold a walking machine in place during a spin. Get help before tilting or moving the machine, because a washer is heavier and more top-loaded than it looks.

When to call a technician
Call when the load is balanced, the machine is level, the pump filter is clear and a rumble still rises with the spin: that is the tub bearing or the suspension, and both are behind the cabinet on these models. Ask for the quote before agreeing to it, because a bearing job on a machine of this class is often close to replacement cost.
