The short answer
An AEG DHP dryer that is completely dead is usually stopped at the door, at the outlet or at a protective device, and all three are checkable without tools. A dryer needs power, a door the machine registers as closed, and a start circuit that has not been interrupted. A machine that does nothing at all is failing one of those, and they can be separated in a few minutes from the front. The table below lists one model for this family, so there is no second configuration to rule out before you begin.
What happens when you press start
- Nothing at all when start is pressed — A power question before it is an appliance question.
- It has power but start does nothing — The door circuit or the start switch is not completing.
- It hums on start with the drum still — Power is reaching the motor; either the belt has gone or the motor is jammed.
- It runs only while start is held in — A classic start-circuit signature, and a useful one because it narrows the fault to a switch.
- NEAR MISS — it starts and turns but gives no heat — That is a heating fault and the heating page for this family is the right one.
What is holding it, most likely first on the DHP line
- Power at the outlet, cord and protective devices — A dryer usually sits on a heavy circuit of its own, so nothing else in the room reports when that circuit opens and an owner easily assumes the machine has failed. On the DHP family this holds without qualification, because the family covers one configuration rather than a spread of them.
- The door not registering as closed — It will not run with the door open by design, so a worn switch or a door that no longer closes firmly reads to the control exactly like an open door.
- A broken drive belt — A broken belt gives the distinctive hum with a drum that spins freely by hand, and it is the only cause here that can be confirmed with no electrical work at all.
- The start switch, motor or control — The residual once power, door, thermal fuse and belt are proven, and the point at which the work needs the machine isolated and a meter.
The order to work through on these models
- Check the protective devices for the dryer circuit, then inspect the plug and outlet for heat damage — Costs nothing and settles the largest single group of cases.
- Close the door firmly, listen for the switch and try again — The condition most likely to be unmet on a machine that has power.
- Turn the drum by hand: no resistance at all means the belt has gone — Separates a mechanical fault from an electrical one by feel.

Isolate it first
Safety
Isolate the machine at its breaker, or draw the plug, before any panel is disturbed — stored charge can remain in a capacitor once the supply is gone. Give the cabinet time to cool: drum skin, heater housing and duct all stay hot well past the end of a programme. The door switch stays exactly as the factory wired it, since it removes power from heater and motor the instant the door opens. A dryer must never be run venting into the room, nor with its duct damaged. On a gas machine, a smell of gas means touching no switch at all: leave the building, then call the gas utility from outside.
When to call a technician
Call a technician once power, the door, the duct and the belt have all been proven and the machine is still dead, because the next step is a meter inside the cabinet with the machine isolated. Call without waiting if the machine operates its protective device the moment it is switched on, if the plug or outlet shows heat damage, or if anyone has felt a tingle from the cabinet.
