--- title: "Heat-pump dryers" description: "Miele heat-pump dryers — every dryer Miele sells in the United States is a heat pump, and there is no vented model to compare it to." url: "https://mielemiami.support/appliances/dryer/" date_modified: "2026-08-22" --- # Miele heat-pump dryers ### Three machines, one circuit TXB, TXF and TXR — the differences are programs and steam, not mechanism. All three are ventless, all three run on a standard household circuit, and all three collect their condensate in a container unless they have been plumbed to a drain. ### What actually goes wrong - **The filters and the condenser block.** The owner’s half of the machine, and the cause of most “it does not dry” calls in this climate. - **The condensate path.** The container, its float, the pump, or the drain it was plumbed into. - **The sealed circuit.** Compressor, evaporator, refrigerant sensors. Not an owner’s job and not improved by running it again. - **The moisture sensors in the drum**, which decide when the cycle ends and which read wrongly when they are coated. ### Why humidity here is part of the diagnosis A ventless dryer takes its air from the room. In a South Florida laundry closet in August that air is already close to saturated, and the machine works harder and clogs faster for it. Ventilation into the room matters on this appliance in a way it does not on a ducted dryer, and it is worth saying where the machine stands when you book. ### What to have ready when you call The model number from inside the door, the number on the display, whether the machine drains to a container or to a pipe, and when the condenser block was last cleaned.

What to have ready when you call The model number from inside the door, the number on the display, whether the machine drains to a container or to a pipe, and when the condenser block was last cleaned. ### Why is a heat-pump dryer different to repair? Because there is no element and no duct. It dries by moving heat around a sealed refrigerant loop, condensing the moisture out of the air and collecting it — so the parts are a compressor, an evaporator, a condenser block and the sensors watching them. Twenty-four of the twenty-eight conditions Miele publishes for its dryers are in that group, and that is the shape of the machine rather than a sign yours is unusual. ### Everything comes out damp and there is no error at all. Start with the two things the owner controls: the filters, both of them, and the condenser block behind the lower panel. In this climate they load faster than the interval in the book, because the air the machine is drawing already has water in it. A dryer that has never had its condenser cleaned will dry badly for a long time before it complains. ### It says the container is full and I just emptied it. Then it is not the container, it is the float or the pump that empties it — or, if the machine is plumbed to a drain, the drain. Worth mentioning when you book which way yours is set up, because they are two different checks. ### Is it slower than my old dryer? Yes, and that is by design rather than something to fix. A heat-pump dryer runs cooler and longer, which is why the clothes last. A cycle getting noticeably longer than it used to be, though, is a real signal — that is usually the filters or the condenser. ### Can it be stacked on the washer? Yes, with the maker's kit, and most of the ones we see are. It means both machines come apart to reach either, which is planned time on the appointment. --- **[Read full article: Heat-pump dryers](https://mielemiami.support/appliances/dryer/)**
