Error code 8 on a Siemens Surpresso coffee maker indicates an internal technical fault. This error is somewhat vague and can arise due to a variety of issues with any of the internal components of the machine. Common reasons for this error may include problems such as:

1. Bent or Broken Pins: One possibility is that the pin on the contact bowl is either bent upwards or broken off, which prevents the bowl from being detected properly.

2. Microswitch Issues: In some models, the error can occur if a microswitch, particularly related to the dip tray, is not functioning correctly. If the switch isn't actuated, it can lead to an error.

3. General Internal Malfunctions: The ambiguity of the error suggests there could be several other internal parts that might be malfunctioning.

For troubleshooting, it's recommended to check the contact bowl and dip tray for any visible issues and ensure all components are properly connected and functioning. If the problem persists, consulting a professional or referencing the user manual may be necessary for further assistance.
