Turn the supply valve fully on; a half-closed valve can starve the fill. If it comes back, it needs a visit. ### How much water flow does a Bosch need to avoid E18? Bosch asks for a supply of about 10 liters per minute. A valve that is only partly open can fall short of that. ### Does E18 mean my Bosch pump is broken? Not necessarily; both checks Bosch gives for E18 are on the supply side, the valve and the inlet hose. Book a visit only after those are confirmed. --- **[Read on the site: Bosch dishwasher showing E18 | DishwasherRepair.center](https://dishwasherrepair.center/error-codes/bosch-e18/)** **[Book a visit with DishwasherRepair.center](https://dishwasherrepair.center/schedule/)**
