Washing Machine Servis M6601S Leaking from underneath?

Hi my servis waching machine has just started leaking on a bog standard 30 degree wash from underneath.

I have pulled it out cleared up the water checked the u bend and the pipes are connected fine and tightly and it fills up and drains, spins fine when its empty.

It seems to be just when its loaded up a bit and its got a massive 6kg drum but its never overloaded usually 2 thirds full if that. So I'm a bit baffled. Only just come out of its warranty aswell...

Any help would be appreciated as I can afford to get a engineer out at minute got a baby due in a few weeks time and still got loads to get :(
