Lost manual to LG washing machine WF-T502c Fuzzy Logic. Just want to know where detergent and softener go?

I do not know this model. However, on other top load LG washers, the powdered detergent goes in a box at the back (top) of the washer, and the fabric softener when diluted gets poured into a spot near the left side of the top of the washer. (The bleach goes near the front of the washer.) For front-loading washers, the detergent and fabric softener are poured into the detergent drawer. The largest compartment is for detergent (wash cycle) and is usually on the left. The smallest compartment is for fabric softener.

Manuals for most LG appliances are available at their site. Start at http://www.lg.com/au/support/product/support-product-profile.jsp?customerModelCode=WF-T502C&matchedModelCode=NOT_MATCHED&searchEngineModelCode=WF-T502C&initialTab=documents&targetPage=support-product-profile . The manual is in a DjVu format.
A partial manual is also available here: http://monitor.diplo-best.com/review/LG/WF-T502C . You will need to review the washer or enter a code.

I hope this helps.
