How to Troubleshoot & Replace Samsung AP4579129 / DC67-00444A Washer Max Fill Cap

I recently lost my max fill cap on my Samsung washer and after that, the detergent holder would not drain of water after washes. After a quick replacement order of the max fill cap, the soap dispenser is no longer holding any excess water after washes. 

Googled the problem, watched several videos. Recommendations were to replace blue cup and top piece. 

Purchased a new Liquid Soap tray and Max Fill Cap. The Max fill cap is supposed to snap into the soap tray and ours no longer did so it floated in the water preventing the siphon action from emptying the cup. The new Liquid Soap tray also has a small hole (1/16") in it to let the excess water slowly drain out. The water remaining in the tray really isn't a problem unless you spill the water when emptying it. You just need to empty it to be able to add detergent. 

APP had it verified the fit, Ordered it. Put it in. Done 

Just unpacked and placed it in- easy peasy. 

Replaced missing parts 

I ordered a slightly different p/n (DC97-14493B) and being I'm a fairly capable DIYer, I made a minor modification to make the part I needed (DC97-14493A). The opening for the Assembly Guide Water, Silver Care Kit was blocked. I carefully drilled small holes in the four corners of the opening and using a very sharp knife, I cut out the plastic blocking the opening. Note: the schematic molded in the top of the plastic housing was incorrect for my model, so mark your water lines first or use the schematic off the old housing. 

Find the piece on internet. I ordered it. 

I bought a new cap from AppliancePartsPros.com. 

Replaced the inexpensive soap dispenser tray.
