James B Roanoke , VA August 16, 2020 Appliance: General Electric Dishwasher GSD4800J01BB Ge Dishwasher Gsd4800j01bb: Water did not drain completely. How to replace Valve Body Gasket. I replaced the piston valve, valve body gasket, and the solenoid assembly. I thought, why not replace everything just to be safe. Plus the total cost was about $80; which is still less than what a repairman would charge just to make a house call to give an estimate. I followed the videos and from start to finish took me about 1.5 hour. My dishwasher is working like new again. Thank you for making the repairs easy and affordable.
