The windscreen washer does not work. What can be the reason for this?

If the windscreen washer is not functioning, there are several potential issues that could be the cause.

1. No water in the reservoir: This is a common issue that can easily be overlooked. If there's no fluid available, the system cannot spray water on the windscreen, which is crucial for maintaining visibility while driving.

2. Defective fuse: The windscreen washer system relies on electrical components, including a fuse. If the fuse is blown, power won't reach the washer motor, leading to a malfunction.

3. Blocked jets: Sometimes, dirt or debris can clog the jets where the washer fluid is sprayed. This blockage prevents the fluid from reaching the windscreen, impairing visibility.

According to German traffic regulations, maintaining visibility is essential for safe driving. A vehicle's windscreen washer system is a critical safety feature that contributes to this visibility. It is important to ensure that all components of the system are functional to comply with safety standards and to prevent accidents caused by impaired visibility. Hence, understanding and addressing all possible issues is vital.
