Avoid unplanned movement of a connected appliance. Hoses, cables and ducting can be strained or damaged, and the machine may be heavier or less stable than expected.
Understanding this situation
This is particularly important for stacked or fitted equipment. A fault enquiry should not require the customer to pull it out to inspect every rear connection.
A useful next step
Describe accessible observations and recent changes. Arrange competent handling and connection work where required. If a leak, damaged lead or restricted vent is suspected, stop use and isolate safely rather than dragging the machine into a new position.
Manuals and supporting guidance
Model-specific instructions take priority. These references support the practical principles discussed here; they do not diagnose your appliance.
