Washer-dryer combo shows E12 and may stop mid-cycle; often related to overheating or temperature sensor issues in drying mode.

Safety first: Unplug the unit and allow it to cool completely before servicing.

• Clean all filters: Remove and thoroughly clean the main lint filter and any secondary filters or condenser screens.
• Inspect airflow paths: Check the air intake and exhaust paths inside the combo for lint buildup. Use a vacuum with a brush attachment to clean ducts.
• Locate dryer NTC sensor: Typically mounted on or near the dryer heater housing or exhaust duct. Inspect wiring for damage or loose connections.
• Test NTC (advanced): Measure resistance at room temperature and compare with Equator specifications. Replace if readings are out of range.

If cleaning and sensor replacement do not resolve E12, the control board may be misreading temperature or failing to regulate the heater and should be checked by a technician.
