Display-code format

This first Thermador batch is limited to the United States dishwasher support library. E04, E14, E15, and E27 remain direct professional-service cases; E12 allows only exact-model descaling guidance, and E18 only visible supply checks plus one monitored fill. Bosch, Siemens, and other BSH-brand meanings are not inherited.

These themes help you choose the closest code record, but they are not a diagnosis by themselves.

Before checking a code

Match the exact brand, appliance type, and display code first. Stop if there is water near electrical parts, burning smell, or any visible damage.
