Have the detergent drawer and siphoning trays been cleaned?
The dispenser should be cleaned periodically to remove buildup from detergent and other laundry products. Buildup causes the water to overflow and leak out. Remove the tray and detach the siphoning pieces. Using a soft cloth or brush and warm water clean the trays thoroughly.
Pull out the tray fully and press in on the center tab to remove the dispenser drawer for cleaning.
