Collected water can spill, and a wet floor near electrical appliances creates a separate hazard. The container should be handled according to its designed grip and emptying method.
Understanding this situation
A full tank may be heavier or less balanced than it appears. Tilting it against controls or setting it on a stacked machine risks accidental spills where access is already restricted.
A useful next step
Let the dryer reach its safe stopping condition, remove the tank as directed and empty it without rushing. Refit it properly afterwards. If water has entered electrical areas, stop use and seek suitable advice rather than simply wiping the outside.
Manuals and supporting guidance
Model-specific instructions take priority. These references support the practical principles discussed here; they do not diagnose your appliance.
