i20 Washer Fluid Sensor Fault
Summary of the thread
A 2010 Hyundai i20 was experiencing a persistent 'washer fluid low' warning despite a full reservoir, and the windshield washer system stopped working. The issue was suspected to be related to the washer fluid sensor or pump circuit, possibly due to a wiring or connector fault. After inspection, the problem was identified as a faulty level sensor in the reservoir, which was replaced, resolving the issue.

Wiring harness, you say? So, you think it might be a short or something? Where exactly should I be looking for these connectors? Never really dug around in that area before.

Indeed, a short circuit or corroded connector is plausible given the error code and system malfunction. Focus your initial inspection on the wiring and connectors near the washer fluid reservoir and the pump motor. Consider consulting a vehicle-specific repair manual for detailed schematics and component locations. However, due to the complexity of modern vehicle electrical systems, I would recommend bringing it to the workshop.

Thanks for the help. Turns out it was a faulty level sensor in the reservoir. Replaced it for 25€, and all is well. That electrical connector was a bit of a pain to get to, though!

The symptoms you describe, specifically the erroneous low fluid warning coupled with system failure and a stored error code, strongly suggest a fault within the windshield washer system's sensor or pump circuit. Have you verified the integrity of the wiring harness and connectors leading to the washer fluid level sensor and the pump itself?
