Locate the droplets
Describe the outer edges, centre trim or internal liner and whether both doors close normally. Mention a recent change in the room or fitted cabinet.
Keep the explanation qualified
A wet trim alone cannot establish a defective seal or heater. Model-specific assessment can consider accessible controls and closure where suitable, without assuming every moisture complaint is repairable.
A useful distinction
External droplets can be influenced by the room, while internal pooled water may need a drainage enquiry. Explain which surface is wet so these two complaints are not combined into an unsupported seal diagnosis.
