Switch the machine off at its button and leave it off for a full five minutes. If it comes back, it needs a visit. ### I just descaled my Bosch and both symbols still blink. Did the descale not work? Probably it did. The descale reminder alone goes out after a finished descale cycle, while both symbols blinking together is Bosch's sign of an error that blocks drinks. Do the five-minute power rest first. ### Will filling the tank stop the flashing on my Bosch? Only if the tank symbol is lit on its own. When it flashes in step with the descale symbol, a full tank does not clear it, because the machine is reporting something other than low water. ### How long should I wait before my Bosch counts as needing repair? Bosch gives one step: off for five minutes, then back on. If the pair returns after that restart, further restarts rarely help, and the next step is a visit. --- **[Read on the site: Bosch espresso machine: Fill Tank and Descale symbols flash together](https://coffeemachinerepair.center/error-codes/bosch-fill-tank-descale-flashing/)** **[Book a visit with CoffeeMachineRepair.center](https://coffeemachinerepair.center/schedule/)**
