If your Low Washer Fluid Warning Light is on, it means the washer fluid reservoir is low or empty. While this doesn’t affect how your car drives, it reduces visibility by preventing you from cleaning your windscreen, which can compromise safety. Topping up or inspecting the washer fluid system resolves the issue quickly.

What does it mean if the Low Washer Fluid Warning Light is on?

This warning light comes on when the sensor in the washer fluid reservoir detects a low fluid level. It’s a reminder to refill the reservoir with washer fluid designed for your climate and driving conditions.

Common causes of the Low Washer Fluid Warning Light

• Empty washer fluid reservoir
• Washer fluid leak from a cracked reservoir or hose
• Faulty washer fluid level sensor
• Incorrect fluid type or contamination

Why do you need to fix this problem quickly?

A dirty windscreen reduces visibility, especially when driving in rain, dust, or at night. Without washer fluid, your wipers alone may smear dirt or debris, making driving unsafe.

How do you know when to get it checked?

You should book an inspection if:

• The warning light remains on after topping up the fluid
• You notice fluid leaking under the car near the front
• Your washer jets spray weakly or not at all
• The wipers leave streaks even with fluid topped up

What happens during an assessment?

A mechanic will:

1. Check the washer fluid reservoir level and top it up
2. Inspect the system for leaks or cracks
3. Test the washer pump and jets
4. Check the washer fluid level sensor for faults
5. Ensure the system sprays correctly and clears the windscreen

How much does it cost to fix?

Topping up washer fluid typically costs $20–$40. Repairing a leak or replacing a washer fluid sensor may cost $100–$300+ depending on the vehicle.

Is it unsafe to drive with the Low Washer Fluid Warning Light on?

While it won’t damage your car, it is unsafe to drive without washer fluid, as a dirty windscreen reduces visibility and increases accident risk. The issue should be resolved promptly.
