Thermador Refrigerator Error Codes – Solutions
Below is a list of the error codes you will find in a Thermador refrigerator and how you can solve the errors:
1. E01
When you see this error code, you know that a sensor in the refrigerator is either defective or has a short circuit. This means that one or more of the sensors of the refrigerator cannot communicate with the main control board.
Use a multimeter to test the resistance of the sensor(s). First, remove the thermistor from the unit so that the temperature of the unit will not affect it. If the sensor’s temperature is room temperature and it reads 6.2k ohms, it is not defective.
But if the reading of the ohms is not close to this figure, consider replacing the sensor.
Call a Thermador refrigerator technician to verify the fault and fix it if you cannot do it yourself.
2. E02
When you see this error code, be aware that a sensor in the freezer is either defective or has a short circuit. This means that one or more of the sensors in the freezer cannot communicate with the main control board.
Test the resistance of the sensors in the freezer using a multimeter. This is to keep the freezer’s temperature from affecting the sensor’s temperature. When it warms to room temperature, yet the reading on the multimeter is not close to 6.2k ohms, then consider replacing the sensor.
Contact the Thermador Service Center to request service in order to verify the fault and fix it.
3. E05, E06
These error codes indicate that the evaporator sensor of the refrigerator section is out of touch with the main control board. It could be that the wire connections between the main control board and the sensor are loose and need to be reconnected.
Check the connections and reattach any loose ones. Also, check the wire harness to see if it is still effective. Replace it if it is not.
But if the connections are intact and the harness is still working, consider replacing the evaporator sensor.
4. E07
The error code points to the fact that the evaporator sensor of the freezer section is not communicating with the main control board. The connections of the wires that link the board and the sensor could be loose, or the wire harness is no longer working.
Change the wire harness if it is defective and reconnect loose wires if there are any. However, if all these are in proper working order, consider replacing the sensor because it is a defective part.

5. E10
The firmware or software in the power module of the refrigerator has failed if you see this error code displayed on the control panel.
To fix this problem, check the module to see if it is just out of touch. If it is, then reset it to get it in proper working order again. But if it is not working anymore, replace it.
However, if you cannot do these yourself, consider contacting the Thermador service center to request a service agent. You can also call a qualified technician to fix this for you.
6. E11
The software or firmware in the display module has either failed or has an error if this error code is displayed on the control panel.
To fix this error, see if the module is still working but is just out of touch. If that is the case, then reset it so that it can start working again. But if the module is no longer working, then replace it.
However, if you cannot do these yourself, consider contacting the Thermador service center to request a service agent. You can also call a qualified technician to fix this for you.
7. E15
If this error code suddenly appears on the display of your Thermador refrigerator, then check the unit’s temperature. It is most likely warm by now.
The possible cause is the failure of one or more of the sensors of the refrigerator. The defective would need a replacement.
But it could also result from an improperly closed door, blocked vents or worn door seal. Check these to be sure none is causing the refrigerator to get warm.
8. E20
There is no communication between the display module and the power module if you see this error code displayed. Check the wire connections between both modules and check the main control board. But it is advised to seek the help of a qualified Thermador refrigerator technician to verify the fault and handle it.
9. E33
When you see this error code, you know that there is clumped ice in the ice maker. You will need to remove the ice cube container and empty the ice in it. Also, check the ice maker to see if the ejector blades move to remove the ice from the mold. Irregular ice use can cause the ice to clump in the ice maker and ice storage bin.
And a leaky gasket will also cause the ice to clump in the ice maker and storage bin. However, other issues, such as low freezer temperature, can cause excessive freezing. Have a refrigerator maintenance agent take a look at the ice maker to determine what is truly causing clumped ice in it.
10. LOWPOWER
This error message lets you know that the supply of power to the refrigerator is not enough. There are a few things to verify in order to fix this problem.
One, check the power cord of the refrigerator for any damage, especially if there has been a power outage or power surge recently.
Two, check the power outlet into which it is plugged to see if it is still working. Also, check it to be sure it is capable of carrying the refrigerator.
Three, be sure you are not plugging the refrigerator into an extension cord. An extension cord cannot provide enough power for a refrigerator and can damage it. Plug the unit directly into a wall socket and be sure that the socket is dedicated solely to it.
Contact a refrigerator technician to find the fault and fix it if all these are in place.
11. FILTERCHG
This indicator reminds you that the water filter is due for a change. Change the water filter, and the message will take care of itself.
Due to the fact that the water is something you regularly use, change the water filter every 6 months. Do this whether the refrigerator alerts you or not. This precautionary health measure ensures mold and bacteria will not grow in the filter and extend into the dispenser.

12. Door Open
It is clear from the message that the door of the refrigerator is not properly closed. Be sure that no item in the refrigerator keeps the door from closing fully. Rearrange the contents to make more room and reduce them if there are too many items in it.
However, if nothing keeps the door from closing yet you still get the message, check the door seal or gasket. If it is leaking or worn, replace it; if it is dirty, clean it with mild soap and warm water.
Contact a refrigerator technician or a Thermador service agent to address the issue if you do all these but still receive the error message.
It is important to know when the refrigerator needs to be replaced. Some errors and faults arise due to the age of the refrigerator. Fixing one could lead to another fault appearing and may no longer be economical. So if the unit is showing too many errors and faults, consider replacing it or getting another unit to support the old one.

Thermador Refrigerator E30 Error Code – Fixed
This error code is for the ice maker in a Thermador freezer and indicates a problem with the machine. Check for ice buildup inside and around the machine, and ensure the shut-off arm moves freely. Also, ensure the water supply to the ice maker is not restricted; the water line may be frozen, or the inlet valve may have stopped working.
Inspect these parts and fix the faulty ones. If the water line is blocked, clearing it is crucial. Check to see if it is ice; use warm water or a hair dryer to thaw it. But you will need to flush the tube if there is debris. You can also turn the main water supply valve to ensure it is completely open. A partially-closed valve can reduce the water pressure and restrict the supply to the ice maker. Seek professional assistance to fix the water supply issue if none of the above works.
Recap
Many of these error codes need the expertise of a qualified refrigerator technician or an experienced Thermador refrigerator engineer. Don’t hesitate to contact one or the other if fixing the faults begin to prove too technical.
However, if you have the expertise to fix the errors, switch the refrigerator off before you begin. You can do this by unplugging it from its dedicated wall socket or shutting the circuit breaker for that part of the house down. Doing this will not only keep you safe, but it will also keep your refrigerator safe.
Additionally, buy replacement parts from trusted dealers. Buying the wrong parts due to affordability will damage the refrigerator in the long run. You may end up spending more than you saved in fixing the unit.
