@Vitor, Thank you so much! This is exactly what I was looking for! 👍👍👍

Hello, assistance needed please I also have a Bosch SGS43B42EE99 dishwasher, and I downloaded the repair guide mentioned above. Could someone clarify how to test the power supply and what parts to test initially? I’m a bit confused by the wiring diagrams. Any advice would be appreciated!

Start by checking the basics: 1. Power Supply: Use a multimeter to test the outlet and the terminal block where the power cord connects to the dishwasher. You should see around 120V (or 240V, depending on your model). 2. Door Switch: This is a common failure point. If the door isn’t fully closed or the switch is faulty, the dishwasher won’t start. Test the switch for continuity with a multimeter. 3. Thermal Fuse: If the dishwasher overheated, the thermal fuse might be blown. Check it for continuity as well.

I think my dishwasher has an electrical problem because it won’t start at all. I’m not very tech savvy with fixing things, but I’m willing to give it a shot. I have a multimeter and some basic tools. Can anyone guide me on how to start? I’ve heard the control board, motor, or door switch could be the issue. Any suggestions would be appreciated, can provide serial number if needed!

This is my checklist for diagnosing a faulty dishwasher: Electrical Supply: Check the dishwasher is getting power. Check the socket and terminal block as well. Door Switch: Test for continuity. A broken switch can stop the dishwasher from starting. Fuse: Check if it’s damaged. Replace it if necessary. Control Board: Inspect for visible damage or disconnected connections. Pump and Motor: Test for continuity and confirm they’re working properly.
