# Siemens E22 Error Code Your Siemens dishwasher has displayed the E22 error code, which means water isn't circulating properly through your appliance during the wash cycle. This typically happens because debris or limescale has built up inside the filter assembly, blocking the flow of water to the spray arms that distribute water across your dishes. The good news is that E22 faults are often straightforward to resolve without calling out an engineer. In many cases, homeowners can fix this themselves by cleaning or replacing the filter assembly, which catches food particles and other debris during normal operation. Your lower spray arm may also be blocked or damaged, preventing water from spraying effectively once it does circulate. Before you worry about expensive repairs, it's worth checking both the filter assembly and the spray arm for any visible blockages, limescale buildup, or damage. These components are designed to be user-accessible, and cleaning them is a simple maintenance task. However, if you're not confident working inside your dishwasher, or if cleaning doesn't resolve the error, you may need professional assistance to diagnose the exact fault.
