Plan the programme around safe attendance, not only its finishing time. A continuous wash-and-dry cycle can occupy several hours and should not be left operating while everyone is asleep.
Understanding this situation
The machine combines water, movement and heating processes, and an abnormal event may require a prompt response. A delay-start feature or familiar automatic programme does not eliminate the electrical safety concern.
A useful next step
Choose a period when someone is available and follow the model's use guidance. If the cycle cannot fit that period, separate the tasks appropriately. Do not use an unattended night cycle to avoid the inconvenience of a machine that already behaves abnormally.
Manuals and supporting guidance
Model-specific instructions take priority. These references support the practical principles discussed here; they do not diagnose your appliance.
