What it is
The washers must deliver enough liquid to let the wipers clear the glass. Both an empty or weak jet and a pump that does nothing at all will be recorded as a fault.

What you can do about it
Most of the time the bottle is simply empty, which makes this one of the easiest of all to stay ahead of. A blocked jet can often be cleared with a pin and a squirt of water.
