Timothy O Sunnyvale , CA April 16, 2020 No power Found the main power switch on our 23 year old Bosch dishwasher had all its locating tabs broken off. Had to order a new one. Install went well, but still no power. Looked up schematic on the web, found no L1 power at pin 4 of power switch. Followed it back, found melted wire nut in junction box under base of machine. Have enough wire on power cord to re-terminate hot, neutral, and ground. Dishwasher works. Found broken tine from dish rack in wastewater pump impeller. Probably caused high current on the pump motor. Do-It-Yourself Rating: Repair Time Estimate: 1-2 hours
