Expert Washer System Failure

Strange, I had a similar problem with my Expert. Check the hose is connected properly; it can come loose. Is the system making any noise when you try to use it? It could give you a clue where the fault lies.

Thanks! When you say 'system,' do you mean just the headlight cleaning, or also the windshield washer?

Both! My washer jets weren't working AND the headlight washers were dead. If the hose is fine, it might be more than just a simple connection issue, and I would recommend visiting a workshop.

I checked the hose, it was fine. Took your advice and booked a workshop appointment. They confirmed a defective pump, and the repair cost 165€. Thanks for the help!
