Hello and welcome to the forum.

Your washer bottle is wired in series with the water header tank, you can short the 2 wires together to see if the warning goes out.

Wheel bearings are fairly easy things to change, cleanliness being the orfer of the day.

The little red keys are for disarming the alarm
