Wascomat Washer-Dryer Error Code 85: No Vacuum Detected
Code 85 on the Selecta II dryer unit means the vacuum or pressure switch did not close within 12 seconds of start. It is E 15 in the Selecta II manual. Clean the lint filter and check the exhaust, then call us if it returns.
Medium: the dryer stops without proven airflow, which protects it from heating with no air.
What does Wascomat error code 85 mean?
The dryer section proves that air is moving with a vacuum or pressure switch, which should close soon after the fan starts. The Selecta II unit of the Wascomat WD4130 and WD4240 waits 12 seconds. If the switch has not closed by then, the unit shows ERROR 085 / NO VACUUM DETECTED, which the manual lists as E 15. It stops rather than heat without proven airflow. The manual gives no causes and refers the reader to the Selecta II service manual. The likely themes, which are not stated in the manual, are a blocked lint filter or exhaust, a fan that is not moving air, or a switch or hose that is not sensing the pressure. Cleaning the lint path is the first, safe step. If the fan runs and the lint path is clear but the code still appears, the switch or its hose is the next suspect.
