I brought it to the dealer and he couldn't figure it out. We fill the fluid in the washer and it's fine. About 6-10 hours later the light will come on. The fluid level is still the same so what gives? Could it be a faulty sensor? But then shouldn't a faulty sensor flicker on and off. This one goes ona nd stays on. We can't see any evidence of fluid leaking.

 

I would guess the sensor...
