What UP Means
Thermador explicitly documents that "UP" is not an error code — it indicates the dishwasher's software has been updated.
Common Causes of UP
- A completed software update to the dishwasher's control system

Press any program button to clear the notice.
⚠ Why You Shouldn't Go Further Than That
- No repair action is needed — Thermador states directly this isn't a problem.
Opening a panel to inspect or repair something yourself doesn't automatically cancel your manufacturer's warranty — but it can risk accidental damage, and some manufacturers do have specific service conditions. Check your product's warranty terms, or ask us, before deciding.
