I found soapy water pooling in the bottom of my DW after it's last running. I took apart the sprayer and stuff in the bottom to clean it . I found pieces of plastic and crud caught under neath the sprayer and 'panp. I cleaned it found mor plastic and want o see if this solves my drainage problem. Now I do not remember how the items came out. I want to replace it so I can test the DW before pulling it out and claening the pipes. How do I 'latch' the sprayer into place?
