Karcher FC5 floor washer (Batheaston)

This is unwanted but may need some repair. I can't get cleaning liquid to come out. The bottle is full and the jet doesn't appear blocked. It still works fine if you're prepared to squirt the cleaning fluid on the floor. Someone wanted it a few weeks ago but didn't collect and there were other people interested if it was a 'no show'. If that was you then please get in touch again. since I can't see previous messages (ad was automatically removed after it was promised).
Matt.
