Is it possible to change the door opening direction on the dryer?
Yes, on many models the door opening direction can be reversed. You'll find this information and the exact procedure in the manual for your specific appliance.

What is the difference between the dryers available?
Dryers mainly differ in technology (most commonly condenser models with a heat pump), drum capacity, energy efficiency class, noise level, and extra features such as steam programs, smart app control, or a self-cleaning condenser.

What type of connection kit can be used?
To safely place a dryer on top of a washing machine, you need a stacking kit from the same manufacturer, compatible with your specific washer and dryer models.

There is water at the bottom of the dryer, is that normal?
A small amount of residual water near the filter or at the bottom of the drum after a cycle is common. If there's more than that, check that the filters are clean and that any condensate drain hose isn't blocked.

Can the dryer be connected to a drain?
Yes, most modern condenser dryers allow direct connection to a drain using a supplied or separately purchased hose. This removes the need to manually empty the condensate container.

After connecting the dryer to the drain, there is always water in the reservoir after drying.
Check that the drain hose is installed correctly, isn't kinked anywhere, and has enough slope. A small amount of residual water in the tank is normal, but it shouldn't keep filling up.

Can I connect the dryer to the same drain as the washing machine?
Yes, this can be done using a Y-piece for the drain (a dual trap). The installation must be done correctly to prevent water from flowing back into either appliance.

There is no water in the condensate container even after several drying cycles.
If the dryer is connected directly to a drain, this is completely normal – the water simply drains away and the container doesn't need emptying. If it isn't connected, check whether the filters or condensate drainage system are blocked.

The laundry is still damp after the program finishes.
Try selecting a higher drying level, such as "Cupboard Dry Plus." Other possible causes include an overloaded drum, dirty filters, or a soiled moisture sensor that needs cleaning.

Can I adjust the drying temperature on the dryer?
Setting the temperature directly in degrees Celsius usually isn't possible. The temperature is controlled automatically based on the selected program (cotton, synthetics, delicates, etc.), though some programs offer a gentler, lower-temperature option.

Why does the program time lengthen or shorten?
Modern dryers use moisture sensors to measure how damp the laundry still is. The displayed time is just an estimate that adjusts dynamically as the clothes dry — this is normal behavior and ensures efficient drying.

The dryer completes the drying program after a few minutes (with a small load).
When drying a very small load (e.g., a single item), the moisture sensors may not read reliably, causing the program to end early. For small loads, it's better to use a timed program instead.

Can I dry laundry in the dryer?
Always check the care symbols on the garment label. A square with a circle inside means tumble drying is safe; if that symbol is crossed out, the item shouldn't go in the dryer.

Is it possible to use a cleaning agent for heat pumps on all types of dryers?
No, cleaning agents are specific to a particular model or series. Only use original products recommended by your dryer's manufacturer to avoid damaging it.

What is the drying temperature and why can't I adjust the drying temperature?
Heat pump dryers operate at lower temperatures, typically between 50–60°C, which is gentler on fabrics. The temperature is set automatically by the program — manual adjustment isn't possible, in order to ensure proper fabric care and energy efficiency.

Do I need to connect the dryer to a drain?
No, you don't have to. All condenser dryers come with a removable condensate container, and connecting to a drain is just an optional convenience.
