Electrolux Washer-Dryer Error Code 85: No Vacuum Detected
Error code 85 means the vacuum/pressure switch did not close within 12 seconds of machine start. The manual equates it to E 15 in Selecta II. A technician should follow that service manual.
Medium: the dryer will not heat without proven airflow, while washing is not affected.

What does Electrolux Professional error code 85 mean?
A dryer must prove that air is moving before it heats. A vacuum or pressure switch senses the airflow and closes when the fan has pulled enough air through the machine. The dryer program unit starts the fan and then waits for the switch to close. If the switch has not closed within 12 seconds of machine start, the unit stops and shows ERROR 085 / NO VACUUM DETECTED. The manual gives the Selecta II code as E 15 and lists no causes, referring the technician to the Selecta II service manual. In general terms, no vacuum means the fan is not moving enough air, the switch or its tubing is not working, or the airflow path is blocked. The washing function is not involved. Operators see the dryer fail to start heating, or stop within seconds of beginning a drying program.
