GLA Washer Fluid Warning and System Failure

My 2020 Mercedes GLA diesel shows a low washer fluid warning even though the reservoir is full. The windshield cleaning system doesn't work, and the error memory has a related error. I think it's the wiper water level. Has this happened to anyone?

A 2020 Mercedes GLA diesel displayed a low washer fluid warning despite a full reservoir, and the windshield cleaning system was non-functional. The problem was suspected to be related to the wiper water level. A possible cause was identified as a faulty fluid level sensor, which was confirmed upon inspection. Replacing the sensor resolved the issue, restoring the windshield cleaning system's functionality.

I had a similar problem with my GLA. It's probably a sensor issue or the washer motor. Check the fluid level sensor connector for corrosion. Sometimes, the sensor malfunctions even if the reservoir seems full. If that's okay, the washer motor might be faulty. It might be worth checking the fuse box too. Did you notice any unusual noises from the washer motor before it stopped?

Thanks for the input. Where is the fluid level sensor connector located? Is it easy to get to, or do I need to remove parts?

On my car, the connector was accessible from under the wheel arch, near the washer fluid reservoir. You might need to partially remove the wheel arch liner for better access, but it's fairly straightforward. If you're not comfortable doing that, it's probably best to take it to a workshop. It might save you some trouble and potential damage.

I appreciate the advice. I inspected the connector, and it looked fine. I took it to a workshop. The issue was a faulty fluid level sensor. The replacement was 25€. The windshield cleaning system is now working.
