Error code
Beko Dishwasher E10 — Code Meaning
PDF pages 10 and 25 identify E10 as a communication warning for the conductivity-based water-hardness sensing system, on models fitted with that automatic sensing board. Beko’s German repair portal supplies this Arcelik dishwasher troubleshooting document (November 2020, version 0.0) under product 7646793977 / BDIN37541WP. It covers stored service-diagnostic codes and optional features, not a universal normal-use display list. A technician must confirm the platform and installed features; the portal association alone does not prove every listed feature is fitted.
