Need Appliance Repair Help? Ask a Technician for Answers ASAP
Hi,Welcome to Just Answer, My name isXXXXX will be helping you with your appliance issue today.
Nothing lights up at all? This is completely dead?
Okay, means the main control board has failed, it will need to be replaced, do you have a voltmeter and tools to take this machine apart? It's important to check the power going into this board before replacing it, this is an expensive part and if you don't have the tools to check it you may want to call a Bosch technician in to make sure this is the issue, according to the service manual it saying replace the main control board, it's not sending any power up to your interface, the interface is the control that lights up where you set the wash cycles, you can purchase this board at the following link, http://www.repairclinic.com/PartDetail/Circuit-Board-or-Timer/1094535 hope this helps, thanks, Bryan.
Before replacing anything plug a lamp or something into the outlet the washer is plugged into and make sure there's no power interruption between the breaker and the receptacle, picture or something else works and unplugged before doing this.
