Narrative:

Ready for pushback; flight attendant from door 2L came to cockpit to indicate that door 2L was not arming properly; that the wedge was not coming out. [I] went to door 2L to investigate. Looking at door; moved lever to disarm and looked again. Opened door handle and it was apparent that door was not disarmed; door with assist opened partially. Slide was attached at bottom and partly out of pack. I tried to close door but slide then deployed. No one was hurt; no one else was involved in manipulating the door. Maintenance was called and it was determined that the slide would be replaced and flight to operate with a delay.
