All 18 documented Thermador fault codes — organized by fault type, with what each one means and what to check before calling.
When a Thermador appliance detects a reading or component behavior outside its normal range, it stores a fault code and often lights an indicator on the control panel. These codes point to a specific sensor, relay, or circuit rather than describing the visible symptom directly.
This page covers all 18 documented Thermador codes we have on file, grouped by fault type below. Each code links to a full breakdown of what it means, what’s usually behind it, and what’s safe to check yourself before calling a technician.
Most units store fault codes on the control panel, but the exact way to view them varies by model. Rather than risk the wrong sequence on your specific unit, check your owner’s manual for your model, or let a technician pull the stored codes during the diagnostic visit.
Oven and range fault codes almost always trace back to the control board, a temperature sensor, or a heating element/igniter — the same handful of components across every brand.

Cooktop fault codes cover gas burner ignition, induction element faults, and the control board driving them — issues that show up as a burner that won’t light, won’t stop sparking, or an induction zone that won’t heat.
| Code | Appliance | What It Means |
|---|---|---|
| Burner Won't Ignite | Star Burner Gas Cooktop | A Thermador Star Burner that clicks but will not light is almost always caused by a dirty or wet… |

Refrigerator fault codes cover cooling, defrost, and the sensors and fans that keep a built-in unit at temperature — the same components that fail across every refrigeration brand.
| Code | Appliance | What It Means |
|---|---|---|
| Defrost Fault | Refrigerator | A Thermador Freedom column defrost system fault means the automatic defrost cycle is not clearing… |
| Evaporator Fan Fault | Refrigerator | A Thermador Freedom column evaporator fan fault means the fan that circulates cold air off the… |

Dishwasher fault codes usually point to a drain, fill, or leak issue — problems that are often visible, like standing water or a blinking light, before the code ever appears.
| Code | Appliance | What It Means |
|---|---|---|
| E01 | Dishwasher | Thermador dishwasher error E01 indicates an internal electronic control fault, where the main… |
| E09 | Dishwasher | Thermador dishwasher error E09 means the flow-through (instant) water heater has failed or its… |

Every fault code corresponds to a specific sensor, relay, or circuit reading something outside its normal range — not necessarily a symptom you can see or hear. The code itself tells a technician, or you using this page, roughly where to start looking.
Most units display the code directly on the control panel, sometimes alongside a fault indicator light. The exact way to view stored codes varies by model, so check your owner’s manual for your specific model, or let a technician pull it during the diagnostic visit.
Power-cycling the unit at the breaker for about 60 seconds clears many codes temporarily, but if the underlying cause hasn’t been fixed, the code will return. Clearing the code isn’t the same as fixing what triggered it.
No — some alerts, like a water reservoir prompt, resolve on their own once the triggering condition is fixed. Most component-level and control-board faults do need a professional diagnostic, since confirming the actual cause usually requires testing with a meter.
The underlying components are similar, but Thermador-specific models and control boards benefit from brand experience, which is why we diagnose by model rather than guessing generically.
That can happen with an intermittent fault that hasn’t been actively triggered at the moment you check. A technician can usually still retrieve the stored code history during a diagnostic visit.
