Headlight Washers Leaking

One of my headlight washers has developed a leak.

I have checked hose connection found the leak is in the body section that swivels (the other end of the part the hose is connected to)

Can this leak be fixed or will the entire washer assembly need replacement?

I had this once when the washer liquid froze inside it, the whole assembly had to be replaced which necessitated removing the bumper - luckily it was under warranty.

Now it is out of warranty I ensure I put in enough washer antifreeze to prevent it happening again.

Mine certainly has not frozen, we are in the middle of a summer heatwave and below zero tempatures may occur one night every few years.

If the bumper needs to be removed to fix the headlight washer am I better off disconnecting the headlight washer and blocking the hose?

It is leaking quite quickly ie there is a pool of water under the washer and its currently 39 degrees celsius.

Sorry, I didn't notice you live in Australia.

You could, of course, block the hose and leave it like that. Personally I am just too curious to see what the problem is, I would just have to take it off and fiddle.
