Check the documented language or setup menu for the exact model before interpreting unfamiliar wording as a hardware fault. A changed setting can make normal prompts difficult to recognise.
Understanding this situation
Avoid pressing sequences copied from a different appliance, because they may alter other settings. If the display also reports an error, preserve the message as shown so it can be identified correctly.
A useful next step
Use the manufacturer's manual to restore the preferred language where a user setting exists. If the controls cannot be understood safely, leave the programme unstarted. Keep a clear image of the screen and the model rather than guessing the meaning of an unfamiliar instruction.
Manuals and supporting guidance
Model-specific instructions take priority. These references support the practical principles discussed here; they do not diagnose your appliance.
