There are a few reasons why the service door could pop open during use:
1) The brewing unit is not installed properly in the unit. You can try turning the unit off, remove and reinstall the brew unit, and then turn the unit back on to see if it reset itself.
2) The latch on the service door has coffee build up and is restricted from moving freely. Please clean the latch area and make sure the door closes.
If this problem persists, please contact us M-F between 9am-8pm est at 1 866 528 8323.
