Options are commonly tied to the selected programme. Changing the programme can remove a setting that was available before, so the previous combination should not be assumed to carry across unchanged.
Understanding this situation
A low-temperature delicate cycle, for instance, may not offer the same intensive wash or high-speed treatment as a robust cotton setting. The relevant question is whether your particular model lists that option for the new programme. Repeatedly pressing the control cannot make an unsupported combination safe or valid.
A useful next step
Read back the final choices before starting and use the manual's programme table when a symbol disappears. If an explicitly supported combination cannot be selected, note the appliance's full model and the control sequence. This is more useful than a general report that all buttons are broken, and avoids unnecessary resets that may erase the original settings.
Manuals and supporting guidance
Model-specific instructions take priority. These references support the practical principles discussed here; they do not diagnose your appliance.
