Why Your Windscreen Washer Jets Aren’t Working (And How to Fix Them)
If your windscreen washer jets aren’t spraying properly, you’re not alone. This is one of the most common issues UK drivers face—especially during colder months.
The good news? Most problems are quick to fix, and in many cases, the issue comes down to the type of screen wash you’re using.
Common Reasons Your Washer Jets Aren’t Working
1. Frozen Screen Wash
In winter, weak or heavily diluted screen wash can freeze inside your system.
Signs:
- No spray at all
- You can hear the pump working
Fix:
- Let the system thaw
- Switch to a properly mixed solution designed for colder temperatures
Frozen washer jets are usually caused by incorrect dilution.

2. Blocked Washer Jets
Dirt, wax, and residue can clog the tiny nozzles.
Signs:
- Weak or uneven spray
- Spray going in the wrong direction
Fix:
- Gently clear the nozzle with a pin
- Clean with warm water
Low-quality liquid screen wash is a common cause of residue build-up over time.
3. Empty Washer Fluid
It sounds obvious—but it’s often overlooked.
4. Faulty Pump
If you hear nothing when activating the washers, the pump may need replacing.
How to Prevent Washer Jet Problems
Most washer jet issues can be avoided with the right screen wash solution.
Traditional liquid products can:
- Be over-diluted
- Leave residue in pipes and nozzles
- Freeze in colder temperatures
Use a consistent, pre-measured solution that avoids all three issues.
