Washine machine waste water pouring out of pipe

XEO25

Hi, just bought a new home and have fitted our washing machine. All working fine but when it drains the water pours out of the white connector in the wall (a little hole at the top of the white connector). 



I've taken the u bend off the bottom (red line in photo) to see if its blocked, but it seems clean. I haven't managed to inspect the rest of the pipework for blockages yet as it's hard to get off.

Is the issue likely a blocked pipe or is there an issue with the white connector? I don't know why it would have a hole in the top where water could escape but I'm sure there's a good reason.

Thanks to anyone who can help

Take another picture and mark a red arrow where it leaking

One would normally use a stand pipe of between 450mm to 750mm high. Yes, you can use a fitting similar to what you have there, But I would suggest something much higher and have an air admittance valve at the top. Also suggest that both of the flexi pipes are pinned to the wall above the height of the waste pipe connection - This will help to stop water draining back in to the appliances.

I would assume that it's at the top of the white T-connector, where the blue-marked (water) is gushing from....

Never assume anything regarding leaks

Here's the hole where the water shoots from, top of the t connector

Whilst I agree with you, I was only pointing out that the OP had already indicated where the leak is....

Most probably small crack in the fitting, clean it off and gently move the fitting to see if there’s a split ?
Personally I would have um separate, if it blocks the both machines affected.  

Yes as FB says the standpipe is to low.

So nothing to do with the hole?

No picture when I posted. but can see it now, Never seen a hole like that in that type of fitting.
Maybe I can presume (😂)  some clown has drilled a hole to try and unblock the pipe in the past ???
As I said above always best to keep them separate, lazy plumber or bad Diy 
Quickest solution is to replace the leaking fitting, but not the best option.
