Quick answer: A grinding washing machine is one of four things: drum bearings worn (loud rumbling on spin, gets worse with RPM), suspension rods or shocks worn (banging + grinding on spin from the cabinet), drain pump impeller (grinding during the drain cycle only, often a foreign object), or a foreign object trapped between the inner and outer tub (grinding throughout the cycle). When the grinding happens tells you which one. Brand-specific bearing kits, pumps and suspension parts in our Sydney warehouse — same-day dispatch.
Identify the noise by when it happens
| When the grinding happens | Likely cause |
|---|---|
| Only during spin, gets louder with RPM | Drum bearings |
| During spin, with banging against the cabinet | Suspension rods / shocks |
| Only during the drain cycle | Drain pump impeller / foreign object in pump |
| Throughout the cycle (wash, spin, drain) | Foreign object between inner and outer tub |
Pin down the timing — it cuts the diagnostic tree in half before you open a panel.
Cause 1: Drum bearings (most expensive, most common after 8+ years)
The outer tub rides on two sealed bearings at the back of the drum. They’re sealed against water at the factory, but the lip seal (rubber boot between the wash water and the bearing race) perishes over the years. Once water gets in, the bearings rust and start to grind.
Symptoms:
– Loud rumbling only on spin, like a jet engine spooling up.
– Gets worse as the cycle ramps RPM.
– Often paired with a small water stain on the floor behind the machine (lip seal leak).
– Drum has noticeable play when you grab it and rock it side-to-side (front-loader, door open).
The fix: Bearing kit replacement — lip seal + both bearings as a set. This is the biggest job on the list — the drum has to come out of the cabinet, which on most front-loaders means a half-day with a workshop press.
The parts (Bosch examples — same pattern other brands):
– Bosch washing machine lip seal + bearings kit — fits WAP24160AU, WAP24261AU, WAS24460AU and WAS28461/28464AU AU-spec models.
– Bosch seal + bearings kit — fits WAS32440AU55 and WAS32741AU23.
For F&P, Samsung, LG, Electrolux bearing kits — run your model through the Part Finder.
Honest call: if your washer is 10+ years old and the bearings are gone, the cost of a bearing kit + a tech with the press equipment often approaches the cost of a new mid-range machine. Get a quote both ways before committing. We’ll tell you when it’s not worth fixing.
Cause 2: Suspension rods / shocks (manageable yourself)
The drum hangs from suspension rods (top-loaders) or sits on shock absorbers (front-loaders). When these wear, the drum starts whacking the cabinet on spin — usually accompanied by a grinding noise as parts that shouldn’t touch each other now do.
Symptoms:
– Grinding with banging during spin.
– Loud thumps if the load is unbalanced.
– Drum sits low or slumped (front-loader) or feels floppy when you push it side-to-side (top-loader).
The fix: Replace the suspension rods (top-loaders) or the shock absorbers (front-loaders). 30-60 minute job on most brands.

Cause 3: Drain pump impeller (cheap, fast yourself)
The drain pump impeller is a small plastic propeller inside the pump body. When a coin, bra wire, or fragment of a smashed glass gets past the filter, it can jam between the impeller and the pump housing — grinding noise during the drain cycle only.
Symptoms:
– Grinding only during the drain phase, not during wash or spin.
– Sometimes the machine throws a drain fault code (LG OE, Bosch E18, Samsung 4C/5C, Electrolux E10) at the same time.
The fix: Pull the kick panel, access the pump filter, clear the foreign object. If the impeller itself is chipped, swap the pump.
Full step-by-step in our washing machine not draining guide — same diagnostic path, since grinding-on-drain usually escalates to won’t-drain within a few cycles.
Cause 4: Foreign object between inner and outer tub
Underwire from a bra is the all-time #1 culprit. Coins, hair clips, kid’s small toys — anything small enough to slip through the drum holes lodges in the gap between the inner (perforated) drum and the outer (sealed) tub.
Symptoms:
– Grinding throughout the cycle, every cycle.
– Sometimes a metallic clink on rotation in addition to the grinding.
– No drain or spin fault — the foreign object isn’t blocking flow, just scraping.
The fix: Get inside the outer tub. On top-loaders, sometimes accessible from the bottom of the drum (lift it out). On front-loaders, this is a tub-split job — half-day with workshop space. If you can hear the object move when you rotate the drum by hand, that’s the confirmation.
If you’re already replacing drum bearings (Cause 1), this is the time to clear any foreign objects too — both jobs require the tub to come apart.
Frequently asked questions
Why does my washing machine make a grinding noise only on spin?
Grinding only during spin that gets louder with RPM — like a jet engine spooling up — points to worn drum bearings. Confirm by rocking the drum side-to-side with the door open: noticeable play means the bearings are gone. A small water stain behind the machine is another giveaway.
What causes a washing machine to grind only when it drains?
Grinding during the drain cycle only is usually a foreign object — a coin, bra wire or glass fragment — jammed against the drain pump impeller. The machine may also throw a drain fault code such as LG OE, Bosch E18, Samsung 4C/5C or Electrolux E10 at the same time.
What causes grinding all the way through the wash cycle?
Grinding through wash, spin and drain, every cycle, points to a foreign object trapped between the inner and outer tub. Bra underwire is the all-time number-one culprit. If you can hear the object move when you rotate the drum by hand, that confirms it.
How long does it take to replace washing machine shock absorbers?
Replacing worn shock absorbers on a front loader (or suspension rods on a top loader) is a 30-60 minute job on most brands. Worn suspension shows up as grinding with banging during spin and a drum that sits low or feels floppy when pushed side-to-side.
Is it worth fixing worn drum bearings on a 10-year-old washing machine?
Get a quote both ways first. On a washing machine 10 or more years old, the cost of a bearing kit plus a technician with press equipment often approaches the price of a new mid-range machine. Bearing replacement means the drum comes out — the biggest job on a washer.
