A:Answer Hi Aloha- You may use tablet, packet, powder, liquid or gel automatic
dishwasher detergent in your new dishwasher. GE Appliances recommends using detergent in tablet or packet form. Independent testing has shown this form of detergent is very effective in the dishwasher. Cascade® Platinum ActionPacs™ are an example of this type of detergent. See page 13 of the Owner's Manual: https://products.geappliances.com/MarketingObjectRetrieval/Dispatcher?RequestType=PDF&Name=49-55105.pdf - Thanks for choosing GE. Enjoy! SUE@GEA
