there was a problem on the hose at the front of the sump to the pressure switch/air chamber sagging, therefore holding water in it, and keeps the pressure switch in a full position, make sure the hose is clear of gunge, and it is straight, or slightly tappering back to drain any residue back to the sump, it gave that fault code. a tie tag is normally used in keeping the hose from sagging.
another possible cause.
TELL..
p.s you can check this from the front bottom panel.
