What Does Error E4 Mean?

The E4 error code on your Emilia dishwasher indicates an overflow or water supply/drainage issue. This usually manifests as excessive water inside the unit or pooling at the base, often causing the dishwasher to stop mid-cycle.

  • Water present at bottom of unit after cycle stops

Possible Causes
