What does the E1 Error mean on the USV32?Updated 2 years ago

The E1 Error is an indication that the chamber was not able to pull a vacuum due to a good seal not forming between the lid and the gasket. 

After you ensure that the gasket looks to be in good shape, close the lid, press the 'AUTO VAC & SEAL' button, and then just give a slight press down on the lid. 

You should see the lid draw down and the vacuum gauge begin to move.
