[Easy Fixes] Low Washer Fluid Light Won’t Quit? Try This!

When the low washer fluid light illuminates, it’s a clear signal to refill your vehicle’s washer fluid. Yet, it can become frustrating when, after refilling the washer fluid, the warning light stubbornly refuses to turn off. While in many instances, this persistent light can be ignored, for those looking to reset this light, finding a solution is key. This guide aims to provide the necessary steps to address and reset the low washer fluid light, ensuring your vehicle’s dashboard reflects the accurate status of your washer fluid levels.

How Do You Get The Windshield Wiper Fluid Light Off?

When the car windshield wiper fluid light turns on, it signals that your windshield wiper fluid is low or empty, prompting you to replace the fluid and check your windshield wiper blades for condition. First, check your fluid levels and add more if needed, possibly with some lubricant to aid wiper movement. If issues persist, cleaning out debris around your windshield wipers by using a screwdriver to clear the gap between each blade can help, followed by a soap and water wash to remove any long-stuck debris.

Upon noticing your washer fluid indicator light, it’s time to fill up your washer fluid. This task is straightforward—purchase windshield washer fluid from any auto parts store or gas station, open your car’s hood, and find the reservoir, typically a round plastic tank with blue liquid. After removing the cap and filling to the designated fill line, reattach the cap and start your car; the light should turn off. If the washer fluid indicator remains on, ensure the cap is securely fastened. Should the light persist, consider visiting a mechanic for a potential replacement of the washer fluid level switch or a reservoir deep cleaning.

Why Does My Car Say Washer Fluid Low?

When your car indicates that the washer fluid is low, it’s alerting you that the reservoir’s level is insufficient for proper operation. To rectify this, filling it with fresh water and adding a few drops of household bleach is recommended to maintain cleanliness and prevent microbial growth. This issue may arise from a malfunctioning safety valve or a clogged filter. Attempting to clear any debris by running a hose through it can be an effective first step.

Should the problem persist, it’s possible you’re facing a leak within the system, necessitating the replacement of parts to avoid further complications. Low washer fluid levels compromise your ability to clean your windshield effectively, impacting visibility. If the light stays on after refilling and starting your car, it signifies a deeper issue beyond just low fluid. Initial dashboard lights at start-up perform a bulb check, but warning lights that remain illuminated warrant immediate attention, indicating potential system issues or the need for further inspection and possible part replacement to ensure optimal functionality and safety.

What Are the Signs My Washer Fluid Level Switch Is Failing?

Not Illuminating

When the windshield washer fluid warning light does not illuminate, it often signals a problem with the car washer fluid level switch, indicating it might be bad or failing. For new car owners, it’s crucial to check the fluid level regularly, ensuring it’s maintained at the correct level. Those with older cars should consider having their vehicle serviced by a professional mechanic to address and rectify this issue, safeguarding against potential complications related to the windshield washer system’s functionality.

Always On

When the car washer fluid level switch malfunctions, being either bad or failing, it leads to persistent issues with both the windshield and rear wiper operations. This warning light serves as a critical indicator, suggesting the system lacks sufficient fluid to function as intended. If you find this light always on, it’s essential to first check your antifreeze levels and inspect your hoses for leaks prior to considering the purchase of a new washer fluid pump. This proactive approach can help identify simpler solutions before escalating to more significant replacements.

How To Reset Low Washer Fluid Light?

To reset the low washer fluid light, start by filling up the washer fluid tank after ensuring all debris is cleared from your pump and hose. Using a funnel or a large container can make this process smoother. While a low fluid level in the transparent washer reservoir tank is often the culprit behind the light’s activation, there are instances where the light remains on even after addressing this issue. In such cases, exploring other circumstances that could trigger the low washer fluid light is crucial. Addressing these underlying issues correctly is key to ensuring the light turns off, restoring your dashboard to its normal state.

Bring The Floater Up The Stream

To address a stuck float mechanism in your washer tank, you might need to use a simple tool like a coat hanger or rod. Inserting it down the filler of washer fluid allows you to maneuver the floater mechanism back to its original position. This method can be particularly effective when the low washer fluid light refuses to turn off due to the floater being unable to rise and signal an adequate fluid level, ensuring that your system accurately reflects the current state of your washer fluid.

Use The Gas Pedal

If you’ve refilled your washer fluid but the warning sign persists, a reset of the signal might be necessary. To achieve this, turn the ignition on and press the gas pedal downward five times swiftly, all within three seconds. This procedure is designed to reset the low washer fluid light, a technique that has proven effective for many drivers. It’s a simple yet unconventional method that could very well resolve the issue, restoring the proper function of your vehicle’s warning systems.

Replace The Washer Fluid Sensor

If the low car washer fluid sensor fails, it incorrectly signals your car’s computer about the reservoir’s water level, potentially keeping the warning light activated even after refilling. Should the light persistently stay on post-refill, it’s indicative that the sensor for your washer fluid light is either compromised or damaged. Typically located behind the front bumper and adjacent to the passenger fender, accessible through your car’s glove box, replacing this fluid level sensor could rectify the issue, restoring accurate alerts regarding your washer fluid status.

Repair The Washer Fluid Reservoir

Repairing the washer fluid reservoir is crucial if you find the low washer fluid light persistently on due to a leaky reservoir. Such leaks can trigger the warning light, potentially affecting your car’s performance and posing a risk during night driving. It’s advisable to seek a professional for a thorough fix. The washer fluid level switch plays a vital role by alerting you with a red triangle warning signal when levels are low. Yet, a defective switch might send false signals to the car’s ECU, inaccurately indicating low fluid levels even when the reservoir is full, necessitating a prompt inspection and possible replacement.

Can You Drive With Low Washer Fluid?

Driving with a low washer fluid level is technically possible, but topping it up promptly is highly recommended. If you find yourself on the road with a low washer fluid level, there’s no immediate cause for alarm, but it’s advisable to check the level every two weeks to prevent any potential issues. Continuously operating your vehicle under these conditions doesn’t typically result in damage, but for optimal visibility and to avoid any mishap, addressing the low fluid level promptly is wise. Ensuring your washer fluid is adequately filled will maintain your vehicle’s functionality and safety, especially under adverse weather conditions or dirty windshield scenarios.

How Can You Tell if Your Windshield Fluid Is Low?

When your windshield fluid is low, its effectiveness in washing away dirt diminishes, potentially making driving more challenging, especially during night conditions. A notable sign of low fluid levels is a significant reduction in its capacity to clean the windshield, coupled with a decrease in viscosity, which slows its flow through the system. This may lead to windshield wipers malfunctioning or failing to clean the entire glass surface effectively. Such conditions highlight the importance of regularly checking and maintaining the windshield fluid level to ensure optimal visibility and safety while driving.


The low fluid message on your dashboard serves as more than just an annoyance; it’s a crucial safety feature reminding you to refill your car’s washer fluid reservoir. This warning light does not merely indicate a need for more fluid but plays a vital role in maintaining safety by preventing low visibility conditions that could lead to accidents. Ensuring your vehicle’s washer fluid is adequately filled is essential for safe driving, highlighting the importance of heeding this alert to safeguard against potential hazards on the road.

The washer fluid level sensor traditionally operated through a Reed Switch mechanism within automotive applications. Initially, when the container is full, the float positions itself in a manner that opens the Reed Switch. As the liquid level drops, the float descends, activating the Reed Switch, which in turn triggers a lamp on the dashboard to illuminate, signaling to the driver that it’s time to refill the washer fluid. This system ensured drivers were promptly alerted to maintain optimal visibility by keeping the washer fluid at adequate levels.

The washer fluid level sensor operates as a contactless capacitive sensor, crucial for monitoring the fluid levels within your vehicle’s washer system. Utilizing non-approved washer fluid can trigger this sensor to send a low fluid level signal to the vehicle’s gateway module (either the FEM – Front Electronics Module or BDC – Body Domain Controller). This action, in turn, prompts the instrument cluster to display a low washer fluid warning, alerting the driver to the need for a refill to ensure proper functioning and visibility while driving.

Driving with a low washer fluid level can significantly compromise your visibility, especially under adverse weather conditions or when dirt accumulates on the windshield. While it might seem minor, lacking sufficient wiper fluid in your washer system can lead to a streaked or smeared windshield, ultimately compromising your safety on the roads. It’s essential to keep your windshield clean and clear at all times, ensuring you have enough fluid to maintain optimal visibility and safe driving conditions.

When your washer displays an F8 E1 or Lo FL error code, it’s indicating a problem with detecting the correct amount of incoming water. Such error messages can lead to the washer door becoming locked and the control panel turning unresponsive. This issue necessitates checking the water supply lines for any obstructions or verifying that the water supply valves are fully opened to ensure the washer receives the required water flow for operation.

When the low fluid light persists even after refilling the washer reservoir, it typically indicates a problem with the washer fluid level sensor or the windshield washer system wiring. Under these circumstances, seeking a professional repair service is the recommended course of action. This ensures that any underlying issues are accurately diagnosed and resolved, preventing potential malfunctions in the washer system and maintaining optimal visibility while driving.
