How can I fix error c208?

My wife closed the device without the bottom lid and after 3 seconds the device shot down, stuck bowl, making clicking noise and code c208 pop up. I dried the device, put it back in place, got out the bowl manually, and put it back into the place. Plugged in, but c208 shows all the time. Official troubleshooting guide says it’s locking mechanism: repair when the error continues to appear.

However there is no further instructions on how to repair it anywhere in the internet. Can someone help me ? Much appreciated.
