What does e4 mean on seimens washer?

The "e4" error code on a Siemens washer typically indicates a problem with the water drainage system. This could be due to a clogged filter, a kinked or blocked drain hose, or an issue with the pump. To resolve it, check and clean the filter, ensure the drain hose is properly positioned, and inspect for any blockages in the drainage system. If the problem persists, it may require professional service.
