Before you book
Where to find your Thermador model number / E-Nr
Thermador calls the model number the E-Nr. It is printed on the appliance rating plate. For the refrigerator registration flow, Thermador places the label inside the refrigerator compartment on the right side near the door.
These supported items are based on Thermador owner/support guidance. For any message not shown, use the manual for the appliance rather than a generic code list.
Message / alert · Water filter
Filter reminders and reset steps differ by series.
What it means
The water-filter tracker is requesting attention.
What you can safely check
After replacing the correct filter, choose Go to Filter Management on the alert, then select Reset.
When to schedule service
If the display differs, the alert remains, or the procedure does not match the appliance, use the owner manual or schedule service.
Home Connect · Message / alert
Door left open
What it means
Select connected refrigeration can send a door-open notification.
Safe check
Confirm the door is fully closed and no package blocks the seal.
Schedule service
If the door will not seal or the notification repeats.
Home Connect · Message / alert
Filter reminder
What it means
Select connected refrigeration can remind you when the water filter needs replacement.
Safe check
Identify the correct filter from the complete model label and follow the manual.
Schedule service
If the reminder cannot be cleared with the appliance-specific procedure.
Thermador error codes
Thermador refrigerator error codes, decoded.
These E-codes are the ones most consistently documented for Thermador built-in and Freedom® refrigeration on the shared Bosch/Thermador (BSH) control platform. Definitions can differ between series and production years, so treat this list as a starting point—the complete model number (E-Nr) confirms the exact meaning during diagnosis, and the visit always verifies the fault before any repair is authorized.
Error code · E01
Refrigerator compartment sensor
What it commonly means
The control reports the fresh-food temperature sensor reading out of range or out of contact with the board.
Safe owner step
Note the current fridge temperature, photograph the code and the model label, and press the alarm/reset control once. A single power interruption at the breaker for about five minutes is reasonable if the breaker is safely accessible—do not repeat it.
What repair typically involves
Diagnosis usually confirms the cabinet temperature sensor or its wiring harness; the repair replaces the faulty part and verifies stable temperatures afterward.
Error code · E02
Freezer compartment sensor
What it commonly means
The same class of fault as E01, on the freezer side: the freezer temperature sensor reads out of range or has lost contact.
Safe owner step
Check that the freezer still holds temperature and keep the door closed. Photograph the code; one reset attempt is enough.
What repair typically involves
The freezer sensor or its harness is tested and replaced as needed, with freezer temperature verified before the visit ends.
Error code · E05 / E06
Refrigerator evaporator sensor
What it commonly means
The evaporator-side sensor for the fresh-food circuit is unreachable or out of range. Cooling may continue, but defrost timing suffers and frost can build.
Safe owner step
Do not unload the appliance or remove panels. Note any visible frost patterns and how long the code has been present.
What repair typically involves
The evaporator sensor and its wiring are tested behind the panel; accumulated ice is cleared and a full defrost cycle is verified.
Error code · E07
Freezer evaporator sensor
What it commonly means
The freezer evaporator sensor is unreachable or out of range—the same failure class as E05/E06 on the freezer circuit.
Safe owner step
Note frost buildup and door-seal condition. Avoid repeated resets; they only delay diagnosis.
What repair typically involves
Sensor and harness testing at the freezer evaporator, ice removal if needed, and a verified defrost cycle.
Error code · E10
Power module software fault
What it commonly means
The main power module reports an internal software or firmware failure.
Safe owner step
One power interruption at the breaker may clear a transient fault. If the code returns, stop there and keep the appliance closed.
What repair typically involves
The module is reset or reflashed where supported; a module that will not hold its firmware is replaced.
Error code · E11
Display module software fault
What it commonly means
The display module reports an internal software or firmware failure—controls may be unresponsive while cooling continues.
Safe owner step
Photograph what the display shows, including partial segments. One power-cycle attempt is enough.
What repair typically involves
The display module is reset or replaced; communication with the power module is verified afterward.
Error code · E20
Module communication lost
What it commonly means
The power module and the display module are not communicating with each other.
Safe owner step
Do not remove panels or probe connectors. Note whether cooling continues and photograph the display.
What repair typically involves
The harness and connectors between the modules are tested first; a failed module is replaced only after the wiring is ruled out.
Any other code or segment
Meanings vary by series and year
Why we do not guess
Thermador refrigeration spans several control generations; the same digits can mean different things on different series. The complete model number (E-Nr) fixes the definition.
What to capture
Photograph the full display and the model label, and note what the appliance is doing. Our Thermador code-reading guide covers exactly what to save before the code disappears.
Alpha Pro provides preventive and general maintenance for Thermador refrigeration systems. The appliance design determines which procedures are accessible and appropriate.
Owner maintenance
Routine care between visits
Water filter: replace every six months or when prompted, using the correct filter for the appliance.
Interior and seals: follow official cleaning guidance; keep door seals clean and dry.
Stainless surfaces: clean in the direction of the finish with a mild cleaner; avoid abrasives.
Odor filters: follow the model manual for applicable built-in designs.
A professional visit can evaluate accessible systems without assuming every procedure applies to every model.

2
Evaluate the system
The technician examines the reported condition in context: operation, airflow, water, controls, doors, installation, and relevant components.
3
Review the recommendation
Findings and proposed work are explained before repair proceeds. The residential diagnostic is credited toward an approved repair.

Helpful answers
Thermador refrigerator service questions
Clear preparation makes a built-in service request easier to evaluate.
What Thermador refrigerator information should I have before scheduling?
Have the full model number or E-Nr, the exact symptom, displayed temperatures, photos of any alert or frost pattern, and a full view of the installation.
Where is the Thermador refrigerator model number?
Thermador identifies the model number as the E-Nr on the appliance rating plate. For the covered refrigerator registration flow, Thermador places the label inside the refrigerator compartment on the right side near the door.
Can a cooling symptom identify the failed part?
No. A warm compartment, frost, noise, or temperature fluctuation helps direct an inspection but does not establish which component failed.
Should I move a built-in Thermador refrigerator before service?
No. Leave a heavy built-in, column, or panel-ready appliance installed and share photos of the appliance, cabinetry, floor, access route, and water connection.
How often should I replace a Thermador refrigerator water filter?
Thermador recommends replacement every six months or when the appliance alerts you. Use the complete E-Nr to identify the correct filter and follow the exact owner manual.
Does Alpha Pro provide Thermador refrigerator maintenance?
Yes. Alpha Pro provides preventive and general Thermador refrigeration maintenance. The visit scope depends on the appliance design and the systems that are safely accessible.
Should I repair or replace my Thermador refrigerator?
The decision depends on age, exact model, condition, repair scope, parts availability, installation, and replacement context. A diagnosis is needed before comparing those factors.
What does error code E01 mean on a Thermador refrigerator?
On the shared Bosch/Thermador control platform, E01 most commonly points to the fresh-food temperature sensor reading out of range. Definitions vary by series and production year, so the complete model number confirms the exact meaning, and the diagnostic visit verifies the fault before any repair is authorized.
Should I keep resetting a Thermador refrigerator error code?
No. One alarm reset and at most one power interruption at the breaker are enough. If the code returns, photograph the display and the model label and schedule service. Repeated resets only delay diagnosis.
