It can mean the appliance is waiting before the main programme begins. The displayed number may represent the delay rather than the time left in active washing.
Understanding this situation
Check the exact symbol and manual, especially if the machine seems silent after selection. A deliberate waiting state is different from a fault after the programme has started.
A useful next step
Use the documented method to change or cancel the delay and plan safe attended operation. Do not repeatedly reset a normally waiting dishwasher. If it fails to start after the intended delay, record that specific behaviour and any warning.
Manuals and supporting guidance
Model-specific instructions take priority. These references support the practical principles discussed here; they do not diagnose your appliance.
