Washer-dryer combo shows E16 and stops; may be associated with overheating during drying.

Safety first: Unplug the unit and allow it to cool completely before inspection. Do not bypass safety thermostats.

• Clean airflow path: Remove and clean the lint filter. Access and clean the condenser (if present) and internal ducts as described for E12.
• Check ambient conditions: Ensure the unit has adequate ventilation around it and is not installed in a confined, unventilated space.
• Inspect high-limit thermostat: With the rear panel removed, locate the high-limit thermostat on the heater housing. If it has a manual reset button, press it gently to reset. If it trips repeatedly, there is likely an airflow or control issue.
• Check cooling fan (if present): Verify that any cooling fan near the condenser or electronics spins freely and runs during drying. Replace the cooling fan motor if it is not operating.

Persistent overheating errors after cleaning and basic checks require professional diagnosis of the heater relay and control board.
