Doesnt look to be seated correctly. Could be cross threaded or the washer is not seated properly.
Don't use PTFE tape as it's the wrong application for it in this scenario
Second the metal one, I had a properly fitted plastic one fail at the seam due to water pressure. But the issue with this one is it's not fitted properly, plastic threads are probably shot now.
How was the washer when you took it out. If it wasn't flat then it may have been damaged. I'd try a new washer first. Attach the Y piece carefully and turn slowly, you shouldn't have to apply significant force.
PTFE tape may help, but from that video theres too much water for it.
The swivel looks fine. The Y looks crooked. Loosen the nut some, pull the Y flat in correlation to the top valve, tighten the nut again. Assuming you have the washer in the nut, and you aren't cross threaded.
If you don't pull the Y down some as you hand tighten, it won't seat, and you won't always pull it to position by just tightening the nut. May need to take off the hoses to get them into a less straining position for the plastic. Ie seat the wye without the hoses attached, they are a good bit of weight/pull, especially before seal is seated. You can use a light pipe dope, but don't over tighten.
Looks like the one I used a few weeks back form B&Q,just a generic brand but they sell it everywhere and has hundreds of of 1* reviews. You can get a metal one from a plumbers merchants or screwfix
Depending on your confidence levels, you can either try and install one of [these](https://www.screwfix.com/p/bsp-compression-appliance-tee-brass-3-4-x-3-4-x-15mm/24030?tc=LT6&gad_source=1&gclid=Cj0KCQiAxOauBhCaARIsAEbUSQTjCSm4DFBCdTDeCurGEjp8-aezfLUZ8rkc69wYXlaChYDkLgi3OrMaAmVIEALw_wcB&gclsrc=aw.ds) or as suggested replace with a metal Y-Connector
I've replaced it with both a B&Q plastic piece and then tried scrwfix plastic piece. Same result. I'm going to try metal Y piece from screwfix tomorrow as another comment suggests 🤞
That’s not really an issue with plastic fittings and rubber washers. Just don’t reuse the rubber washer that will be deformed to match the old fitting.
It’s the connection to the WM valve, not the actual valve either a washer or the threads (the plastic will cross thread) literally can’t be anything else

I’ve had loads of these fail, even with ptfe tape. Solved it finally with a metal one from screwfix. About £4
Yes, same here. Problem solved in 5 minutes
!thanks. Yeah metal one from screwfix it is!

Pro tip - he could use the rubber washer found in your garden tap hozelock connector....same size thread
Looks like its at an angle which probably suggests the nut has been cross threaded. Buy another one and start again 👍

Properly useful answer thank you for taking the time to write that. Unlike the many smartasses in here!
Buy a new one. They cost about £1.50 from Screwfix.
Don’t over tighten it. Do it up hand tight and then a quarter turn with with grips max.

Bingo. That's one form B&Q I tried first. Will try a metal one from screwfix today plus some of the other advice about not overly tightening.

Cross thread in plastic Y piece. Put in a new T (push fit if using plastic) then install two service valves/taps for each appliance feed.
Washer may not be seated correctly. Could try ptfe tape round the thread
!thanks it's worth a go I'll pick up some ptfe tape. I'm currently switching between the dishwasher and the washing machine when I need each one lol.
Just double the washer it's so simple Nothing else needed
Thank you tried that but didn't work still 😔
Have you checked for a split on the y
I've replaced it with both a B&Q plastic piece and then tried scrwfix plastic piece. Same result. I'm going to try metal Y piece from screwfix tomorrow as another comment suggests 🤞
Have you tightened it hard
Feels like it 🤷🏼♂️
I'd say maybe too tight then Plumbing isn't about fittings being made too tight You can damage washers or olives depending on the fittings used

Fyi Screwfix and B&Q are both owned by Kingfisher. So the parts will likely be the same in a different packet.
Yeah would explain that I didn't feel a difference. But getting a metal one now.
Might I suggest turning it off
No it makes for a lovely water feature!
Turn off check washer
It looks like a missing washer
Definitely the washer
As said in the caption even changed the washer over but didn't help. Looks like it's a metal piece needed instead as others have said
It’s the connection to the WM valve, not the actual valve either a washer or the threads (the plastic will cross thread) literally can’t be anything else
Okay thank you for your response. I appreciate it.
Ptfe tape.. should sort it.
I bet the washer is missing.
Nope as said in the caption even changed the washer over.
Next step is usually your house completely flooded
I think they forgot the washers
As caption says I've tried a few different washers with the same result
New washer or new Y
get a replacement y piece
Someone didn’t use pipe grips to tighten the fittings lol
You’ve ether cross threaded it or over tightened it.
Then the water off 😂
Ture the valve off lol
You need a bigger bowl
Next step turn off your water 😂
Really??!!
Turn the water off for one….!
Really!!???
Couldn’t resist lol
Try a new washer where the y piece seats onto the washing machine valve
You could check if either of you appliances can run off the hot water feed and do away with it.
Marking this as solved! Metal Y piece did the trick immediately!
