Turn off the water supply valve to the dishwasher right away. If it comes back, it needs a visit. ### Is it safe to keep running my Asko while F40 is showing? No; F40 reports an inlet valve that lets water pass while it should be shut. Close the dishwasher's supply valve and leave it closed until the valve has been serviced. ### Will Asko F40 go away on its own? Asko gives no owner fix for F40 beyond shutting the water and calling service. Treat it as a repair, not a message to wait out. --- **[Read on the site: Asko dishwasher showing F40 | DishwasherRepair.center](https://dishwasherrepair.center/error-codes/asko-f40/)** **[Book a visit with DishwasherRepair.center](https://dishwasherrepair.center/schedule/)**
