Error message with LCMS 6470

Question

Hello, 
 After carrying out the purge of the LCMSMS 6470, we had an error message at the level of the pump which is as follows: degasser's pressure limit violation, shutdown, not ready condition: shutdown, drive off, out valve block position. 
 What should be done to unlock the system? 
 Thanks

Hello, 
 We have carried out several tests with Lab advisor but the error messages persist at the level of the column modules, autosampler and pump. We have checked the firmware version but the message is the following: multi purpose valve position "Blocked" 
 What can be done to remove this error message especially since everything is blocked except the mass part
