Describe the surface
Say whether droplets appear on a nearby cabinet, door glass or floor, and whether the wash stage was dry externally.
Assess the model arrangement
Drying systems vary, so another model's vent advice may not apply. An engineer can consider seals, moisture handling and access where suitable without assuming the appliance needs a new heater.
A useful distinction
Moisture on the outside after a cold room warms is a different observation from liquid emerging during a cycle. State when and where it first appears rather than calling all droplets an internal leak.
