2001 Renault Laguna windscreen washer not working

try looking at the washer bottle,most washer pumps on moden cars slide into a rubber seal located at the bottom of the bottle

As " moley1956 " suggests should be on washer bottle .If motor not working , could check fuse not blown if motor seized . On some models used to be fuse F6 .Common fault with washer pumps was getting clogged up with gunge and if lucky sometimes emptying bottle and refilling with hot water would clear .Not too hot or hose can come off pump.
