Thermador dishwashers use the BSH E-series error code system, shared with Bosch and Siemens dishwashers. The most critical code is E15 (AquaStop water protection), which requires physically draining the base pan before the machine will restart. E24 and E25 are drain-related faults resolved by cleaning the triple filter and clearing debris from the drain pump impeller. E22 means the filter is blocked. E09 points to a heating element or NTC sensor failure. The SA and NL indicators together signal low salt and rinse aid levels. You can enter diagnostic mode by holding the Start button for 5 seconds to cycle through stored fault codes.

Frequently Asked Questions

Do Thermador dishwashers use the same error codes as Bosch?
Yes. Thermador dishwashers are built by BSH Group, the same parent company as Bosch. They use the identical E-series error code system, and many components are interchangeable between brands.
How do I enter diagnostic mode on a Thermador dishwasher?
Hold the Start button for 5 seconds. The display will cycle through any stored fault codes.
Which Thermador dishwasher error code is most serious?
E15 is the most critical. It means water has leaked into the base pan and triggered the AquaStop flood protection. The machine will not restart until the base pan is drained and the leak is fixed.
Can I reset a Thermador dishwasher error code by unplugging it?
For most codes, unplugging for 60 seconds clears the error. E15 is the exception - it requires draining the base pan before the machine will operate again.
