Can anyone tell me where the filter is on an Indesit WIA111?

hi can anyone tell me where there filter is on the Indesit WAI111 please. I lost the manual in a house move last year without ever looking at it. now my machine has started to suddenly leak from underneath. the wash programmes are fine but the leak is not. could be something else wrong but its always best to check filter first i think.
many thanks
