Turn the coffee system off at the main On/Off switch and unplug it before any internal cleaning. If it comes back, it needs a visit. ### How often should I clean inside my JennAir coffee system to avoid GENERAL ALARM? JennAir suggests a look inside about once a week and cleaning out loose coffee whenever you see it. ### Can I vacuum inside a JennAir built-in coffee system? Yes, gently, with the unit off and unplugged. JennAir lists brushing, dusting and vacuuming for loose debris. ### GENERAL ALARM came back the day after cleaning my JennAir. Why? If a proper clean does not clear it, JennAir sends it to service; something inside is holding the alarm beyond surface residue. --- **[Read on the site: JennAir GENERAL ALARM: the inside of the coffee system needs a deep clean](https://coffeemachinerepair.center/error-codes/jennair-general-alarm/)** **[Book a visit with CoffeeMachineRepair.center](https://coffeemachinerepair.center/schedule/)**
