The short answer for the DHP models
On the AEG DHP dryer models, a noise or a vibration that is new leads somewhere the brand-generic article does not put first — the blower wheel or its bearing. The brand-generic ordering opens instead with this: something loose in the drum or in a pocket. It moves down behind the lead here, because this family is one model rather than a range, so the ranking can be specific where a brand-wide one has to hedge.
What you observe on these models
- A squeal that changes with the drum speed — A bearing or a pulley under load rather than a loose part.
- Scraping at one point of every turn — Metal meeting metal at a single spot, which is a glide or a seal that has gone.
- A rattle that is worst at the start of a cycle — Something loose in the drum or in a pocket rather than in the machine.
- NEAR MISS — the drum will not turn at all — A hum with no turn is a will-not-start symptom, not a noise one.
Causes, most likely first on the DHP family
- The blower wheel or its bearing — A rumble that is there from the moment the motor starts and does not depend on the drum being loaded. Ranked first on the DHP models.
- Something loose in the drum or in a pocket — Coins, zips and a stray screw make a rattle that sounds far more expensive than it is. Second.
- The condenser, the water tank and the second fan — A machine that condenses rather than venting has an extra fan, a condenser block and a tank to pump into, and each of them makes a noise a vented machine does not. Third.
- The motor bearings — It is the noise that is present the instant the motor runs and never varies, and it is the only one here that is not a cheap part. Last, and that is the point of the order.
- Body: The spine for the DHP family records a single model code, so there is no variation inside this family to hedge against: what is written here applies to the whole of it. Where this departs from the brand-generic ordering: the cause that moves up on these models is this one — the blower wheel or its bearing — and the brand-generic lead moves down behind it.
Check in this order on the DHP models, and why
- Find out whether your machine vents to the outside or condenses into a tank — First: It decides which half of this list applies, and a condensing machine has noise sources a vented one simply does not have.
- Run the machine empty on an air or no-heat setting — Second: It takes the load out of the equation, and a noise that survives an empty drum is a machine noise rather than a laundry noise.
- Turn the drum slowly by hand a full revolution — Third: Feel for a rough spot and listen for a scrape at one point.
Before you open anything
Safety
Unplug the dryer or switch off its breaker before opening the cabinet — a capacitor can hold a charge after the power is off and a dryer circuit is a high-current circuit. Lint is fuel. If your machine burns gas and you smell gas, do not switch anything on or off: leave the building and call the gas utility or emergency services from outside.

When to call a technician
Call when the drum scrapes or thumps with nothing in it, when the noise is there from the moment the motor starts regardless of the drum, or when the machine has been levelled and the duct cleared and the noise is unchanged. Stop using it and call immediately if you smell burning, if the cabinet is hot to touch, or if the noise arrived with clothes coming out scorched. On the DHP models the line sits where the check stops being one you can make from outside the cabinet. When you book, say that the machine is built in if it is.
