Too little water is coming out of the windscreen washer jets. What can cause this?

The combination of options 1 and 2 is correct because both a blocked jet and a defective washer pump can directly affect the performance of your windscreen washer system.

Blocked jets can occur from debris or buildup, preventing the proper flow of washer fluid. Similarly, a defective washer pump may fail to generate the necessary pressure to push the fluid through the lines, resulting in insufficient fluid reaching the windscreen.

In Germany, keeping your windscreen clear is a legal requirement for safe driving. If you’re unable to see clearly due to inadequate washer fluid, you may face fines or penalties. Therefore, understanding and addressing these issues is essential not only for compliance with traffic laws but also for ensuring safety on the road. Option 3, having too much water in the reservoir, does not affect the flow to the jets and is not a cause of poor washer performance.
