Why is there excessive steam when brewing? can’t see clock!

First check the bottom of the brew basket and the top of the carafe, where the lid pushes up against the brew basket. There’s a “pause-and-serve” mechanism that can get clogged. If it’s clogged or dirty, then coffee doesn’t flow fast enough when its brewing and steam can build up in the brew basket. Also check the top hinged lid to make sure it sits all the way down and seals properly with the top of the housing. Gaps or a loose-fitting lid can let steam escape. Finally, try descaling your coffee maker since scale buildup in the heating element can cause more steam than normal.
