Error 8

The problem with the device's microcontroller is due to incorrectly connecting the sensor, which causes the microcontroller pins to shorten.

Hello guys.

I have a same problem like Mahmoud Abdella but my device is IKA CMAG HS10 Digital.

there is not any comment about "Er8" in manual.

I dont understand mojtabapiri1009013 comment about microcontroller  of this device, my device has 2 microcontroller, which one is broken? how can I solve this problem? I change the microcontroller of Lcd board and I change all of the IC and other parts of circuit, but it does not work.

" mojtabapiri1009013 " if you know please explane me more, thanks.

I am encountering the same issue. Can you please let me know how to solve the issue

from AI: Error 8 on an IKA HS7 hotplate stirrer typically indicates a problem with the temperature sensor. I checked the 4 thermocouple wires to the main board with a TC reader, both read room temperature at the solder side pins. I then noticed I had bumped the connector off at the potentiometer mini board. That fixed it.
