This set of fault codes for some ranges of Smeg built-in ovens and may also cover some cooker models.
Sadly we do not have a note of the oven model numbers that these error codes relate to.
These error codes may not relate to ALL Smeg branded built-in ovens but there is a good chance that they will represent a good number of products and they will all be based on Smeg electronics and components for the most part so should be fairly standard.
Please try to support our site by buying Smeg spare parts from our store and, if you decide that you really need an engineer please support the local repairers that help make this site possible, you can find local repairers using our engineer search facility.
Before you start any investigation of the fault or even remove a panel of the range cooker please read and fully understand this article in full and pay particular attention to the safety and information notices at the bottom of this page as they contain extremely important information!
Smeg Oven Spare Parts
We have purposely not listed any Smeg spares in this article as there is a vast range of spares used by Smeg that can be model-specific as well as range specific.
For spares, if it isn’t glaringly obvious which one is required please contact us and ask and have the model and serial numbers from the rating plate of the oven or cooker.
Please, don’t guess or assume as spares can be altered on a production run with the same model number having several different alternative components used.
Smeg Oven Test Cycle
PROCEDURE FOR APPLIANCES WITH VERSION 1 ELECTRONICS
Produced up to 27/09/2009 (for more information on the modification, refer to the relative spare parts catalogue)
Activation procedure:
- Switch on the oven with PT2 at the first position on the left of the “0”: “00:00” appears flashing
- Hold down PT1 for at least 5 seconds to enter testing:
- All segments of D1 ON and all L1 and L2 ON symbols (where provided) On
- Rotate PT2 to position 0. Press PT1: COLL appears on D1
- Turn PT2 clockwise. For each selected function, D1 displays the corresponding test procedure step. For each step, the various devices are activated as shown in the table below:
- Activate PT1 in sequence as follows: Rotation left, push, rotation right (repeat cycle twice). The display shows the activations of the knob, numbering them from 1 to 6
- Return PT2 to position 0: End of test: board switches to OFF state, the time flashes on D1.
PROCEDURE FOR APPLIANCES WITH VERSION 2 ELECTRONICS
Produced as from 28/09/2009 (for more information on the modification, refer to the relative spare parts catalogue)
Repeat points a, b, c, d of the preceding paragraph.
E. Turn PT2 clockwise. For each selected function, D1 displays the corresponding test procedure step. For each step, the various devices are activated as shown in the table below:
- Activate PT1 in sequence as follows: Rotation left, push, rotation right (repeat cycle twice). The display shows the activations of the knob, numbering them from 1 to 6
- Return PT2 to position 0: End of test: board switches to OFF state, the time flashes on D1
In the case where the tangential motor does not have a dual-speed when the 2nd function is selected, the tangential motor runs at maximum speed.
During the test, the electronic circuit board also checks the temperature sensor connection. In the case of an open circuit or short circuit, “Err1” appears on D1 and the test is interrupted. If, however, the result of the test is positive, nothing appears on the display and the testing procedure continues.
Smeg Oven Fault Codes
These fault codes are written for oven and cooker repairers and not for the general public by Smeg and they assume a certain level of competence on the part of the user in diagnostic routines. We have added some notes to try to assist you in determining the nature of the fault you have but, you will still need to investigate each failure on its own merits. For more help and advice on fault finding on an oven or cooker please refer to our basic fault finding guide from this link before you begin.
Err1 |
Defective sensor detected (open or short)
This error is detected by the software when the signal at the A/D converter, then recalculated based on the voltage/temperature conversion table, continuously indicates an internal oven compartment temperature beyond the range -40°C < Tcf < 600°C for at least 15 seconds. When this error is detected the program in progress stops immediately, all loads open, the cooling motor continues to operate and the alarm is displayed on the user interface in the manner prescribed for each user interface. The program continues to check the sensor input and, if the error condition is no longer present for at least 5 continuous seconds, the error is reset. The interrupted cooking program is not restarted, however. To reset the error switch the oven to the OFF condition. The cooling motor continues to operate for one hour after the OFF condition setting.
|
Err2 |
Over temperature errorActivated in the following cases: If, during a normal cooking program (pyrolysis is excluded from this check), the TSonda exceeds 520°C; the software performs the following operations:
To reset the error switch the oven to the OFF condition.
|
Err3 |
Incorrect probe position
The software has detected bad positioning of the temperature sensor. Essentially the software thinks there is an open sensor or short circuit error and this is managed directly as an error condition, the following algorithm ensures that a badly positioned (but operating) sensor, which would consequently prevent a correct reading of the internal temperature, cannot cause safety problems for the user. The management conditions of the error are as follows:
This error is not managed in the presence of a door lock activation thermostat |
Err4 |
Door lock microswitch activation errorPyrolysis: when the door lock is activated, if the door lock microswitch is not activated within 90 seconds (mechanical problem or the door is slightly distanced from the front so that the door microswitch is activated, but the door lock microswitch is not), pyrolysis is interrupted and the buzzer sounds (1Hz). The display shows the alarm as prescribed by the user interface. The alarm is reset by putting the oven into stand-by condition or by switching the function selector to 0. Regardless of the cause of activation of the door lock (pyrolysis, alarm or breaking of the door lock), if the lock microswitch is activated, the electronic circuit board will be as follows:
|
Err5 |
Fan oven heating element faiulure
This error is only detected during the appliance test procedure. The error is detected if the circular heater element is active when the relative function is not selected (standard operating test abnormality). The RL8 oven fan must be activated. The error does not appear on the display. |
Err6 |
Oven fan motor error
This error is only detected during the appliance test procedure. This error is detected if, when a function is selected, internal fan motor (if required for the function) is disconnected or not working. In this case, the program in progress stops immediately, all loads open and the alarm is displayed on the user interface in the manner prescribed for each user interface, the buzzer is activated (1Hz). The alarm is reset by putting the oven into stand-by condition or by switching the function selector to 0 |
Err7 |
Grill heating element failure
Check the element, switch and regulator if fitted The oven will:
Reset the alarm by placing the display in STAND-BY (e.g. knob set to function 0) |
Err8 |
Tangential cooling fan errorThis error is only detected during the appliance test procedure. This error is detected if, when a function is selected, the tangential motor is disconnected or not working. In this case, the program in progress stops immediately, all loads open and the alarm is displayed on the user interface in the manner prescribed for each user interface, the buzzer is activated (1Hz). The alarm is reset by putting the oven into stand-by condition or by switching the function selector to 0

Smeg Oven Help, Advice And Guidance
Should you need more help and guidance please use the links from this article as most of them will help you to understand your oven a lot better and probably very much help you in diagnosing the fault you have. Of course there are many other articles on the site that will also help you do this.In addition you can post in our forums after registering but please do pay heed to the information below before doing so and read the guides, they are there to help you.You must understand certain things before you begin or attempt any repairs on your own and we want to make these points clear to anyone that decides to investigate one of these or any other oven or cooker:
- We are not responsible for your safety, you are and by using this guide you accept that and accept that any damage that you may cause and work undertaken is entirely at your own risk.
- We will advise the common causes of the fault codes but we cannot guarantee that any parts or work recommended will resolve the issue. It is entirely your responsibility to diagnose your particular problem and resolve it.
- We are not responsible for you buying spares that do not resolve the problem, this is down to your own diagnosis not ours.
- No warranty is inferred, implied or given.
Please understand that these oven and cooker fault or error codes are not a “magic bullet”, they will not tell you what the problem is, they will only offer you an indication of where the problem lies and they are no substitute for good diagnostic skills. You can find out more about what fault codes actually tell you in this article. So please be well aware that, even with this new found knowledge you will still have to actually be capable of investigating and diagnosing the problem and this means adhering to basic appliance safety for working on them.
Please do note that manufacturers can and do change fault codes without notice and we cannot guarantee that these error codes will apply to your particular model as all codes apply to a wide range of appliances and not normally any one specific model. To determine if these fault codes do apply to your particular Smeg oven model please post a request to confirm this in the forums.
