The short answer
On the DHP family the useful question is not that it is noisy but what kind of noise it makes and when. Rumble, squeal, scrape and rattle each point somewhere specific on this platform, and sorting them is what saves a wasted teardown.
What you observe
- A rattle or buzz that changes with the load — Something loose in the drum or a coin in the blower housing, and it comes and goes.
- A scraping noise at one point per turn — Something caught between the drum and the bulkhead, which will mark the drum if left.
- A low rumble that rises with the drum speed — Worn drum rollers or their shafts; the sound is periodic and follows drum rotation.
- A high squeal that fades as it warms — A dry bearing or a glazed belt, typically loudest in the first minutes of a cycle.
- NEAR MISS - noise with no heat — Two faults or one; if the clothes are also cold, read the heating page as well.
Causes, most likely first on DHP
- Belt glazed, frayed or the idler pulley worn — Ranked first on the DHP family: the idler is under tension whenever the machine runs, so its bearing dries out and squeals from cold before it does anything else. These codes share a drum, a blower and a heater arrangement, so a finding on one is worth assuming on the rest. This moves above worn drum rollers or glides, which leads the brand-generic order, because these models share one layout, so its weak point shows across the whole family.
- Blower wheel obstruction or a worn blower bearing — Second: coins and buttons that get past the lint filter end up in the blower housing on this platform, where they rattle at speed.
- Worn drum rollers or glides — Third: the drum rides on supports that wear evenly rather than suddenly, which is why the noise creeps up over months instead of appearing overnight.
- Motor bearing wear — Fourth: last, because a motor whose bearings have genuinely gone usually drags on starting long before it gets loud.
- Something loose in the drum or caught at the bulkhead — Last: the cheapest cause and the one to rule out first, because it needs no tools and explains a sudden change.
Check in this order, and why
- Empty the drum and turn it by hand with the power off — A rumble or a catch you can feel by hand localises the fault before anything comes apart.
- Listen for whether the noise follows drum speed or motor speed — Drum speed points at rollers and glides; motor speed points at the blower or the motor itself.
- Check the lint filter housing and the blower for hard objects — Coins reach the blower through the filter housing and are the common rattle.
- Note whether the noise fades as the machine warms — A squeal that disappears after a few minutes is nearly always the belt or the idler.
Before you open anything
Safety
Kill the power before opening anything, and run the machine only with its panels fitted and its duct connected to the outside. The drum, the blower and the heater all move or get hot.
When to call a technician
Unplug the appliance or switch off its breaker before removing any panel. A capacitor can hold a charge after the power is off. Clearing the drum and the filter housing is owner work. A roller, belt or blower change means the cabinet opens, and on this family the drum has to be lifted out to reach any of them.
