Electrolux EWX 14540W washer/dryer leaking?

My washer had been leaking and tripping the fuse box so called out an engineer on it's warranty, the engineer found none of the pipes to be leaking, however, the venting at the top of the machine wasn't connected and so foam was seeping out.
I put a wash on and newspaper underneath the machine, it is still leaking but not as bad as it was. It seems to be leaking from the under the machine. Checked the door seal and there is no tears, what is it? I am going to fix it myself as I have had enough of the engineers not fixing problems or creating more!
