A control-lock function can deliberately restrict changes. Its activation and release method are model specific and differ from a physical door closure.
Understanding this situation
Check the documented symbol rather than pressing random combinations. A lock retained after a programme can make normal controls appear faulty, but a locked panel does not justify bypassing other safety features.
A useful next step
Use only the manufacturer's owner instructions. If the expected method fails, record the screen and full model. Avoid service-menu sequences from another dryer or opening the panel to force a response.
Manuals and supporting guidance
Model-specific instructions take priority. These references support the practical principles discussed here; they do not diagnose your appliance.
