What to do if my RONDELL RDE-1107 Coffee Maker says the used coffee grounds container is not installed?

If your RONDELL Coffee Maker displays the message that the used coffee grounds container is not installed even when it is, the coffee grounds container sensor may be blocked. To resolve this, remove the used coffee grounds container and thoroughly clean all corners of the container area with the soft brush supplied with the unit. Also, clean all outer corners of the container with a dry cloth.
