Windscreen washers on my W220 not working

[midlife]

Yesterday I ran out of water for the headlight and windscreen bottle and the warning sign came on. I filled it up but did not try it yesterday. However today I went to use it and nothing came out. I thought at first it might be the fuse (f10 which I can't find) but now I don't think its that as I can hear the pump working when I pust the stick in.

Can anyone tell me if there is a resst for this and how you do it or is there something else I can try.

Thanks
