The short answer for the DC models
On the AEG DC dryer models, a machine that will not start leads somewhere the brand-generic article does not put first — a broken belt. The brand-generic ordering opens instead with this: the door switch. It moves down behind the lead here, because the two codes in this family share a platform, so a cause that is real on one is real on both.
What you observe on these models
- It stopped between one load and the next with no warning — A protective device opening is more likely than a component that chose that moment to die.
- The motor runs but the drum stays still — That is a broken belt, and it is a different feeling entirely from a dead machine.
- Nothing at all happens when start is pressed — No hum, no light, no click: that points upstream of the machine.
- NEAR MISS — it starts and then stops part-way — That is a cycle fault, not a start fault.
Causes, most likely first on the DC family
- A broken belt — The motor runs and the drum does not. Ranked first on the DC 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 DC family records two model codes that share their stem and differ only in what follows it, so the two behave as one platform for this fault. Where this departs from the brand-generic ordering: the cause that moves up on these models is this one — a broken belt — and the brand-generic lead moves down behind it.
Check in this order on the DC 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.
- Check the breaker, including both poles of a double breaker — Second: One dead pole can leave a panel lit and a motor dead, which is exactly this symptom.
- Look for a lock or a delay indicator on the panel — Third: Seconds, and it is the cause nobody suspects on their own machine.
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 DC 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.
