What parts are need for a Tricity Bendix BIW105W Filter?

I have a Tricity Bendix BIW105W washing machine which was leaking, so the landlord called in a repair guy the guy was dodgey suggested the filter was missing something and took the part saying he could get a replacement. Never returned. So i am currently looking for the pieces, i know of a couple of sites that sell the parts but am unsure exactly on what is needed to get a working order filter. Does anyone know the exact components to order for the filter or a site where i can order the parts and get it all in one or onsite help other then sorry don't know. The inner components are fine its just the plug in bits i guess the female connector is fine just the male plug and washer etc. Thank you
