Washer-dryer combo displays E17 during drying cycles; drying performance is poor or inconsistent.

Safety first: Unplug the unit before cleaning internal ducts or accessing the blower. Lint is flammable; avoid open flames.

Step-by-step checks:

• 1. Clean lint filter: Remove and thoroughly clean the lint filter before every drying cycle. Wash with warm water and dry if coated with fabric softener.
• 2. Inspect external venting (vented models): Check the wall vent hood for obstructions (lint, bird nests). Ensure the vent flap opens freely during operation.
• 3. Check exhaust hose: Inspect the hose from the combo to the wall for kinks, crushing, or excessive length. Replace with a smooth-walled metal duct if possible.
• 4. Clean internal ducts: Remove the lower front or rear panel and access the internal lint duct and blower housing. Vacuum out all lint and debris.
• 5. Test blower motor: With the unit unplugged, spin the blower wheel by hand to ensure it moves freely. Check the motor for continuity and replace the OEM Monogram blower motor if seized or electrically open.
• 6. Reset and test: After cleaning and any repairs, restore power and run a timed dry cycle. Monitor exhaust airflow and confirm E17 does not reappear.

When to call a technician: If airflow is good but E17 persists, the airflow sensor or control board may be faulty and require professional diagnosis.
