I have an Indesit DA62 dishwasher which frequently has a ground fault which trips the GFCI and I want to troubleshoot this problem but I do not have the wiring diagram. Can anyone supply me this schematic or tell me where I can get it? Obviously, any advice on what may be the most likely cause would also be welcome. I have looked under the machine and there are no obvious signs of leaks. Thanks in advance.
