The short answer
On the Costway EP dryer family a new dryer noise is usually a worn drum support or something loose in the drum, and the two are told apart by whether the noise follows the drum rotation. The brand-generic article lists parts; this page sorts by sound and rhythm, because that is what an owner can actually use on these models.
What you see on the EP family
- A rhythmic thump once per drum revolution — A flat spot on a support roller or a lump on the belt, both of which repeat with the drum rather than with the motor.
- A continuous squeal that rises with the cycle — The idler pulley or a dry roller shaft. It is the most common new dryer noise there is.
- A rattle or a chink that changes with the load — Coins, buttons or a zip pull loose in the drum or caught in the lint path.
- A harsh scraping from the front or rear of the drum — The drum is running on metal rather than on its glides or felts, and that one damages the drum if it continues.
Causes, most likely first on the EP family
- Drum support rollers and glides — Ranked first on the EP family — it is the wear part on the Costway EP dryer family and it accounts for most rhythmic noises on a machine that still runs normally. The drum rides on rollers or on felt and plastic glides that wear flat and dry out. A flat spot thumps once per revolution and a worn glide lets the drum touch the cabinet.
- Belt and idler pulley — Second — it is the other half of the rhythmic-versus-continuous split and it is a cheap part. The idler keeps tension on the drum belt, and its bearing dries out and squeals. A belt that has frayed or developed a lump adds a regular slap to the rotation.
- Foreign objects in the drum or blower — Third — and free to check: turn the drum by hand with the machine isolated and listen for something loose. Coins and buttons work through the drum seam into the blower housing and rattle furiously. A zip pull caught in the lint path does the same at a smaller scale.
- Blower wheel, motor bearing or levelling — Fourth — and the group that includes both the cheapest fix on the page — levelling — and the most expensive. A blower wheel that has loosened on its shaft whirs and knocks, a motor bearing drones continuously, and a machine standing on uneven feet walks and bangs against whatever is beside it.
- Body: With only 2 codes in the EP 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. Run the machine empty and listen for the rhythm — Rhythmic with the drum, continuous, or random. That classification removes most of the candidate list before anything is opened.
- 2. Turn the drum by hand with the machine isolated — Unplug first, then rotate slowly. Roughness, catching and anything loose inside all show up at hand speed.
- 3. Check the lint path and the drum seam for coins — A rattle that changes with the load is almost always something loose that arrived in a pocket.
- Body: The 2 codes in the EP 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. A dryer is heavy and awkward on its feet, so get help before tilting it, and never work on it with the door propped and the drum live. Clear the lint path before any test run.

When to call a technician
Call when the noise is rhythmic with the drum, continuous like a squeal, or harsh like a scrape: all three mean the drum supports, the belt or the idler, and all of them sit behind a panel on these models. Stop using the machine entirely if it scrapes, because that noise damages the drum shell rather than just the part making it.
