UniMac Industrial Washer Door Open Error: Door Open in Cycle
Door Open Error means the UniLinc control sensed an open loading door during a cycle. The cycle is aborted, the Cycle Aborted Error Menu is shown and an audio alarm sounds. The only option is to clear the menu and return to the Cycle Menu.
Medium: the cycle is aborted, and restarting is normally possible.

What does UniMac Door Open Error mean?
This message is the control's response to a loading door that is open while a cycle is running. The control aborts the cycle, shows the Cycle Aborted Error Menu with Door Open Error, sounds the audio alarm and records the event in its Door count. Nothing about it can be resumed: the manual lists clearing the menu and returning to the Cycle Menu as the only option. The cause is most often human, for example a door opened to add an item, to check the load or to stop a cycle that went wrong. When no one touched the door, the door-closed sensor may be misreporting. Door Open Error is distinct from Door Lock Error: the first says the door is open, the second says the lock did not hold.
Affected models and control systems
UniMac UniLinc control on the UW35TV, UW60TV, UW80TV, UW100TV, UW125TV and UW150TV washer-extractors and the UWL, UWN and UWU 035-150 T3 models.
Code numbers and their meaning can change between control generations. We match the full model and control before acting on a code.

Possible causes
Likely causes — what usually sits behind Door Open Error on this control. A technician confirms which one it is before any part is replaced.
- Door opened mid-cycle by an operator
- Door-closed sensor misreporting
- Door seal or latch stopping the door from sealing
- Wiring to the door sensor loose
Safe checks before calling for service
- Clear the Cycle Aborted Error Menu, which is the only option, and return to the Cycle Menu.
- Close the door fully.
- Start the load again from the beginning of a cycle.
- Remind everyone to keep the door shut while a cycle runs.
- If the message appears with nobody near the door, note the Door count and tell the technician.
How a technician diagnoses Door Open Error
- Read the log and the Door count.
- Check the door alignment and the sensor target.
- Watch the door input as the door opens and closes.
- Check the wiring and connector for the door sensor.
- Replace the sensor or adjust the door and test a cycle.
- The door sensor feeds a safety interlock and must not be bypassed.
- Its wiring runs to line-voltage controls.
- Adjusting a door needs tools and care with a heavy loaded door.
How Door Open Error differs from similar codes
Door Open Error says the door is open. Door Lock Error says the door is not locked.
