Turn the machine off and wait until it is cool before you open its door. If it comes back, it needs a visit. ### Can the Gaggenau brewing unit be machine-washed with the other parts? No. Gaggenau lists the brewing unit among the parts that are not dishwasher-safe, so rinse it by hand under running water. ### My Gaggenau Expressive has brown water under the grounds container. Is that this problem? Not quite. Gaggenau traces that to coffee grounds on the hidden side of the drip edge; remove the brewing chamber cover and wipe the edge clean. ### How often does the Gaggenau Expressive want the brewing unit cleaned? Gaggenau suggests taking it out and cleaning it once a week in addition to the automatic rinsing. Doing that keeps this screen rare. --- **[Read on the site: Gaggenau coffee machine: Clean brewing unit](https://coffeemachinerepair.center/error-codes/gaggenau-clean-brewing-unit/)** **[Book a visit with CoffeeMachineRepair.center](https://coffeemachinerepair.center/schedule/)**
