Alex W Saint Robert , MO May 14, 2017 Intermittent problem with my bosch nexxt series 300 washer not draining (e13 code) For over 2 years had my Bosch Nexxt 300 Series washer intermittently giving me an E13 error code. I'd restart it and sometimes it would cycle through fine or not. Finally it started to emit an electrical smell and I was finally sure that the drain pump was the culprit. A front access repair is impossible without disassembling the the complete front panel. Best to attempt the drain pump replacement from the rear of the washer. A pain, but doable... 6 People found this story helpful Do-It-Yourself Rating: Repair Time Estimate: 1-2 hours
