Bosch schematics are notoriously cryptic and look different from the schematics used by other appliance manufacturers. But electricity still works the same way in Germany as it does in Korea, the US, or anywhere else in the known universe. Don't let the unfriendly nature of their schematics fool you into thinking otherwise! Once you understand a few simple conventions used by Bosch, you'll be troubleshooting with Bosch schematics as easily as you use Whirlpool's or any other manufacturer.
In this excerpt from a recent Office Hours webinar, we decoded the schematic for a Bosch dishwasher and used it to troubleshoot various hypothetical problem scenarios. During this webinar, we reviewed five different tech sheets and schematics; this Bosch dishwasher schematic was one of those. Hopefully, this will give you some insight into reading Bosch schematics and using them to troubleshoot.
