What to do if my Drucker Diagnostics 642VFD-Plus Laboratory Equipment machine does not unlock after a run?

The lid should remain locked until the rotor almost stops, then unlock for 60 seconds. For more unlock time, press the 'OPEN / STOP' button while plugged in and stopped. If it remains locked, the electronics may be damaged and require professional assistance.
