Hello Al,
Photos really help when you are trying to describe a problem like this. So if you can, please post photos of the machine itself (not sure what a 5480 series is) and of this plastic piece you say water is dripping off of.
IF it is the bleach dispenser hose leaking, simply plugging it won't help, it will likely be leaking from where the hose connects to the outer tub. Also it will most likely NOT continue many hours later or especially the next day.
Open the top of the washer (the link below is a "how to" video) so you can look down inside from the top. If you don't see anything obvious, run the washer with the top open and look down around the tub as it's running. This MAY help you get a better idea where the leak is coming from.
