The dishwasher performed its own start-up self-test, and one result from the heating electronics was outside what the control will accept, so E04 appears and the machine stops. Thermador documents this code as failing heater electronics found during that self-test. The unit checked itself rather than reacting to your loading, your detergent or the way the door was closed.
1. Turn the dishwasher off with its normal button and let the display go dark. 2. Turn it on again and confirm it powers up and answers the buttons as usual. 3. Leave every panel closed and do not touch any wiring, because the heating circuit runs on line voltage. 4. Write down the code and the model number from the door edge, then call us.
A normal power-up only shows the display and buttons work. The heater test happens at the start of a cycle, so the code may return then. Keep the code number handy for the call.
For this code Thermador points owners to its support line, not to repeated trial runs. Extra attempts will not repair a failed part, and they leave the heating side unchecked for longer.
No. The code names heater electronics, which is a limited area. We confirm which part failed with a meter before quoting, and you get the price in writing before any work starts.
Our technician checks it in your home and hands you a written price before touching anything.
