# Bosch E22 Error Code Guide Your Bosch dishwasher is displaying the E22 error code, which means water isn't circulating through the appliance as it should. This happens when the filter becomes blocked, preventing water from flowing freely during the wash cycle. The good news is that this is one of the more straightforward faults to diagnose and often fixable without calling an engineer. The error indicates a high-priority problem that you'll want to address soon, as a blocked filter will stop your dishwasher from cleaning properly and could lead to damage if left unresolved. In most cases, the culprit is simply a clogged filter assembly that's trapped food debris, mineral deposits, or foreign objects. Occasionally, the lower spray arm can also be responsible if it's become blocked or damaged, preventing water distribution. Before you panic about expensive repairs, it's worth checking these components yourself. Many UK homeowners successfully clear E22 faults in under an hour with just basic tools. We'll walk you through the diagnostic process and show you exactly where to look and what to clean or replace.
