John B Midland , TX February 21, 2015 Appliance: General Electric Dishwasher GLD7400R10BB Ge Dishwasher Gld7400r10bb: Liquid detergent draining from smartdispense reservoir. How to replace Det Dispensing Asm. Very easy repair. Remove front door bottom panel (3 lowest screws from inside of door on left side and right side with #2 Philips screwdriver). Then remove 2 screws on bottom of door with socket set, I believe 1/4". I also used a mirror so I could see what I was doing. Remove cover and the detergent dispensing Asm has 2 screws to hold it down, a hose clamp to hold hose in place and a quick connect electrical connector. Just replace the part and re-install the door and that is it. Part # is AP4340379 (WD12X10251) 2 People found this story helpful Do-It-Yourself Rating: Repair Time Estimate: 30-60 minutes
