As of 2015, Bunn does not make a self-cleaning coffee maker. Bunn coffeemakers should be cleaned every three months to remove mineral deposits. Detailed cleaning instruction videos are available at Bunn.com.
Deep cleaning a Bunn coffeemaker involves placing a quart of vinegar into the brewer and allowing it to sit for at least two hours. Clean the sprayhead using a toothpick to remove mineral deposits, and use the deliming tool to loosen deposits in the sprayhead tube. Next, pour a full carafe of water into the brewer and allow the machine to brew to flush out the vinegar. Flush the coffeemaker with water at least three more times, or until the vinegar smell disappears.
