Dryer displays E18, often with very long drying times and poor condensation on condenser/heat pump models

Safety first: Unplug the dryer and allow it to cool before cleaning internal components.

Step-by-step checks:

• Clean condenser and filters: Remove and rinse the condenser unit (if user-removable) and any foam or mesh filters. Let them dry completely before reinstalling.
• Inspect circulation fan: Access the internal fan that moves air through the drum and condenser. Clean lint from blades and housing. Ensure the fan spins freely and runs during operation.
• Check condenser NTC: Locate the NTC sensor on or near the condenser. Inspect wiring and measure resistance; replace if out of specification.
• Clear air channels: Use a vacuum and brush to remove lint from ducts between drum, heater/heat pump, and condenser.

Note: If E18 continues after thorough cleaning and sensor checks, a technician should evaluate the control system and fan motor.
