IDL500 dishwasher fault?

Hi, I have a IDL500 Dishwasher. I have recently replaced a faulty push switch. When this was removed, it was burnt out. After installing this, the dishwasher will start and at some point in the program is tripping the electrics. I have removed the front panel and checked all switches seated correctly and all appears to be in order. I have also checked filters etc for blockage. I'm sat watching the program now to see when exactly it's breaking, but at a loss what else it could be. I would appreciate any suggestions you may have?
Cheers, Mike
