I foolishly got involved with a used oasis, original issue was a broken door lock, replaced it and a f51 error showed up, rps sensor tested bad and so i replaced sensor and harness, then an f1 error, new board, f2 error, new control, now i get ld but it shows around 25 minute mark after a few minutes of recirculate, drain pump never starts. everything test fine on diag mode, drain pump works, hoses and connections have been cleaned and checked, basket has been removed and reinstalled. i am at a loss. any help would be appreciated.

(also When you start a cycle the fresh water runs for 2-3 seconds, stops, lid locks, then fills through detergent dispenser...)
