Hot water or steam can escape, and the machine's pause behaviour is model specific. Use the documented opening or cancellation procedure rather than pulling the door suddenly.
Understanding this situation
A stopped spray sound does not automatically establish that all contents are cool. Children and pets should be kept away from the open door and hot dishes.
A useful next step
Wait for the permitted safe state before reaching inside. If opening is required because of an abnormal event, follow the manual and appropriate safety guidance. Do not use an open-door wash demonstration to inspect spray patterns or a dispenser.
Manuals and supporting guidance
Model-specific instructions take priority. These references support the practical principles discussed here; they do not diagnose your appliance.
