Check that the drain hose is not kinked, trapped or raised higher than the installation instructions allow. If it comes back, it needs a visit. ### My Bosch shows E:00 and then -18. Is that the same as E:18? Yes. The 800 Series manual shows the drain message as E:00 alternating with -18, while other models print E:18. ### Can too much detergent cause E:18 on a Bosch washer? Bosch lists a high detergent dose among the causes, so reduce it for the next load after clearing the pump. --- **[Read on the site: Bosch washer showing E:18 | WasherRepair.center](https://washerrepair.center/error-codes/bosch-e18/)** **[Book a visit with WasherRepair.center](https://washerrepair.center/schedule/)**
