electric shock

[tootighttopay]

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.

Most likely a faulty earth connection to your diswaher socket, or possibly a faulty appliance.

You need to test your socket for earth fault loop impedance.

Can you post a picture of your supply, meter & consumer unit, please?

Soz securespark i may be leading you up the garden path. The shock isn't like a wack but its more of a strong tingly feeling in your arms which makes you pull away sharpish. This doesn't happen when you are in contact with the outside of the m/c. I have been told by a guy at work its something to do with the control voltage on the appliance and there may be a male spade terminal on the back of the dishwasher to earth onto the water supply to the m/c. The double socket, (which also powers a washing m/c) is wired through a 25A DP isolator switch mounted above the worktops. Any more thoughts on this would be appreciated.

My money would be on exactly what SS says.
