Turn washer around, replace with another washer or replace whole hose.
When I started I spent ages trying to sort out a small thing like this as I preferred to repair than replace. Ended up hardly making any money so now I'll assess quickly whether it's worth trying a repair or not.
In many cases, a customer has tried repairing and because it's not worked for them probably means it won't work for you either.
Same goes for cheap, dripping taps:
Change washer. 1/2 hour and done and paid. Phone call 2-3 weeks later because it's started dripping again. Change washer, 20 minutes, no payment but warning if it goes again then new taps are in order. 2-3 weeks later another call. "How much to change them?" ("I didn't charge you for the last visit, did I?") "Oh, okay, fair enough." One hour, done and paid.
Two hours for that initial pesky tap. Then there's the travel, ordering new taps (trip to merchant or a good 1/2 hour spent on the internet), etc, etc. 1/2 a day altogether and you've earned two call outs, maximum.
Which brings me back to this washing machine hose. 10 minutes to fiddle with washer and/or replace. Then (if you don't have one in the van) off to purchase a new hose and attach it. Hopefully all done and dusted within an hour.
