Washers not working

I haven't used my 2006 Roomster since a garage had the engine out for repairs six months ago but I have just noticed the windscreen washers are not working and no sound from the pump. I have checked and changed various fuses mentioned on posts as its unclear from the fusebox diagram which fuse is responsible for the washers (left hand drive petrol car).

 I wonder if the garage have disturbed a wire or connector during the engine out work so if anyone can advise where to find any likely culprits that would be great.

Advice on what else to check  would be greatly appreciated.
