Some models retain previous selections or provide a saved favourite. That behaviour should be checked against the manual before assuming a dial or memory fault.
Understanding this situation
Remembered options may be unsuitable for the next load, particularly if the fabrics or required treatment have changed. Starting from a familiar display does not remove the need to review temperature, spin and extra functions.
A useful next step
Read back the complete settings before pressing start. If the appliance repeatedly changes a selection against the documented behaviour, record the sequence. Do not use a factory reset casually when it may remove useful preferences or the information describing an intermittent problem.
Manuals and supporting guidance
Model-specific instructions take priority. These references support the practical principles discussed here; they do not diagnose your appliance.
