Manfried,
We had a similar problem to the one which you are describing. It turned
out that the time for the delivery of the solvent was less in that one
cycle than it was in all other cycles, and , therefore, the loop was not
able to fill before time had expired. You might check the times for the
delivery in the blank cycle.
