New starter so please bear with me. I have just installed a new stainless steel sink in my kitchen. I used to have a polycarbonate one. I have noticed that if i happen to be touching the sink and the inside door of my dishwasher i get a bit of a shock. I know something is a bit wrong but i am unsure what it is and how i should go about correcting it. All the pipework is earth bonded back to the CU. Any ideas would be appreciated.
