The short answer for the DHP models
On the AEG DHP dryer models, a machine that will not start leads somewhere the brand-generic article does not put first — the start switch or the push-to-start circuit. The brand-generic ordering opens instead with this: the door switch. 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
- The panel lights but the drum does not move — Power is present and the motor circuit is not being completed.
- A hum but no drum movement — Power reaching the motor and something stopping it, or a start component that has failed.
- It runs only while the start button is held — A classic pattern that points at one particular part of the start circuit.
- NEAR MISS — it tumbles with no heat — If the drum turns, the machine started; the heating page is the one you want.
Causes, most likely first on the DHP family
- The start switch or the push-to-start circuit — A machine that runs only while the button is held has told you where it is, and that is a genuinely common failure. Ranked first on the DHP models.
- The door switch — It sits at the head of the start chain on nearly every dryer, and it is a mechanical part that wears. Second.
- A full water tank or an unseated condenser — A condensing machine will refuse to begin with its tank full or its condenser cover not latched, and both refusals look exactly like a dead machine from the front panel. Third.
- The control or the timer — The most expensive place to start guessing. 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 start switch or the push-to-start circuit — and the brand-generic lead moves down behind it.
Check in this order on the DHP models, and why
- Empty the tank and reseat the condenser cover before anything else — First: Two permissions that a vented machine does not have, both checkable in a minute, and both completely invisible from the panel.
- Open and close the door firmly and listen for the switch — Second: It is free and it is the most common single cause.
- Check the breaker, including both poles of a double breaker — Third: One dead pole can leave a panel lit and a motor dead, which is exactly this symptom.
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 door switch clicks, the breaker is on at both poles, no lock is set, the duct is clear and the machine still will not run — that puts it at the thermal fuse, the start circuit or the motor, all inside the cabinet. Call immediately, and do not use the machine, if the plug or the outlet is discoloured, if the breaker trips as soon as you reset it, or if there is any smell of burning. 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.
