Why does my Kenmore Calypso washer stop and flash the Ld code?

Originally my washer had been stopping in the middle of a load and flashing the FL code, it was also making noise.The repair man said it was the pump so I replaced it today and now it no longer whines or flashes FL but it now stops in the middle of a load and flashes the DL code. What should I check out or attempt in order to remedy this problem? It's very frustrating and it is beginning to tick me off. Thanks for any input can give me.
