Skoda Octavia headlight washers not working

Hi I've just put my dads vrs through the mot and it failed on the headlight washers not working, we operated it about 10/15 times, and all that happens is the windscreen system works, thus proves the fluid bottle level is ok. I gently pulled on the jets and they seem free I.e. Not stuck which was my first thought as this car has stood around for several years. Thus is there a separate pump, electrical relay, fuse for this system? As for the fuse I've had a look at the owners manual and it doesn't list one. Any help would be much appreciated, one website stated from an enquiry from a similar post from somebody else that a hose may have come off as the jets are pushed out under fluid pressure, I will check for this upon my next visit to him.
