Can I stop my Indesit WG1130d washing machine from leaking?

Hi,

Recently my Indesit WG1130d washing machine has started to leak during the very last cycle. For every ten times we use it, it probably leaks five times, so I guess there must be something loose. The strange thing is when I look at it from underneath, None of the tubes seem wet, so I can´t tell where the water is leaking from. Does anyone have any ideas?
