How Thermador codes may appear

Thermador's United States dishwasher support library publishes compact E-number displays including E04, E12, E14, E15, E18, and E27. Preserve the E prefix and both digits, then confirm the complete E-Nr owner manual because code coverage and permitted checks can differ by model and market.
