Hi, assistance required please I too have a Bosch SMV53M90EU32 dishwasher, and I downloaded the service manual shared above. Could someone explain how to check the electrical supply and what components to inspect initially? I’m a bit overwhelmed by the electrical diagrams. Any advice would be great!

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.

The fuses seem fine, I tested it with a voltage meter. Any ideas? 🤔

I believe my dishwasher has an electrical problem because it won’t start at all. I’m not very experienced with repairs, but I’m willing to give it a shot. I have a multimeter and some simple equipment. Can someone guide me on where to start? I’ve heard the mainboard, motor, or door mechanism could be the problem. Any advice would be appreciated, can provide model number if required!

Door Switch: Test for continuity. A broken switch can stop the dishwasher from starting. Fuse: Inspect if it’s damaged. Replace it if needed. Mainboard: Examine for visible damage or disconnected connections. Pump and Motor: Check for continuity and ensure they’re working properly.
