A washer-dryer combination is a washing machine that also dries, in the same drum, without being unloaded. It exists for apartments, boats and any laundry space where there is room for one appliance and not two. The design is a genuine engineering compromise, and most of the complaints about combination machines are consequences of that compromise rather than faults.
The Consequences Worth Knowing Before You Call
- The dry capacity is smaller than the wash capacity. A drum that washed a full load cannot tumble that same load in air with enough room to dry it. Load a combination machine for the drying job, not the washing job, or plan to take half the load out before the dry phase.
- The total cycle is long. Wash and dry run back to back, and a machine that heats its own wash water and then dries at a low temperature is adding two slow processes together. A full wash-and-dry program running for several hours is the design working.
- Drying may use water. Many combination machines condense the moisture out of the drum air against a stream of cold water rather than against a heat exchanger. If yours does, the water supply must be on during the dry phase, and water going down the drain while the machine is drying is normal rather than a leak.
- Results are damper and more creased than a dedicated dryer produces, because the drum is smaller relative to the load and the air path is shared with the wash system.
One Fault Takes Both Functions
This is the part that changes the repair calculation. In a separate washer and dryer, a failed drain pump leaves you with a working dryer. In a combination machine, the drain pump is in the path of both the wash and the drying condensate, so one failure stops everything. The same is true of the door lock, the drum bearings, the motor and the control. There is no half-working state and no fallback, which is why a combination machine tends to be reported as completely dead rather than as partly unwell.
It also means the diagnosis has to be more careful. A machine that fails during the dry phase may have a drying fault, or it may have a drain fault that only shows itself when the condensate has nowhere to go.
The Asko Combination and How It Reports Trouble
The washer-dryer combination Asko documented for the US market does not use fault codes at all. Its controls are on and off, prewash, extra rinse and a set of cycle indicator lamps, and its use and care manual troubleshoots by symptom rather than by number: entries such as the unit not working with the indicator light unlit, and the indicator light being on while the unit still does not work. If you are looking for a code on a machine like this, there is not one to find, and any list claiming otherwise is not working from the manual.
That makes your own observations the diagnostic data. Which lamps are lit, at what point in the cycle it stops, whether the drum turns by hand with the power off, whether water is left in the drum, and whether the fault happens on wash-only and dry-only programs as well as the combined one.
Before the Visit
Switch the machine off at its breaker or unplug it and close both supply taps before looking behind it or opening a pump filter door, and let the drum cool if a hot cycle has just run. Check the drain hose height and the pump filter if your manual documents that as an owner task, since a combination machine is unforgiving about drainage for the reason given above. Then book a washer-dryer combo repair with the model plate photograph and a description of which phase it fails in. On a machine with no codes, that sentence is the code.
