Ian M Foster City , CA August 02, 2015 Appliance: Samsung Dishwasher DMR78AHS/XAA-0000 Samsung Dishwasher Dmr78ahs/Xaa-0000 / : Dishwasher would not power on. How to replace Assy-Pcb Parts(M);Mds. Replaced PCB (Samsung DD92-00008A) located in front door. A capacitor on the board, another chip and part of the board was clearly fried (blackened). A retractable sink faucet sprayer had loosened the outlet under the sink, shaken loose the outlet ground, and knocked loose the dishwasher plug which I assume shorted the dishwasher while running. Product diagrams showed no fuse, and power was still getting to the board so I assumed the board was dead. 3 People found this story helpful Do-It-Yourself Rating: Repair Time Estimate: Less than 15 minutes
