Help ! Where do I connect dishwasher drain hose?

[yellowcone]

As seen in picture the drain hose currently connected is the washing machine , there was a dishwasher before we moved that was taken but I I don’t know where I now connect our new one , so I need some sort of adapter ? Any advice , thanks!

I'd used one of these, https://www.screwfix.com/p/washing-machine-drain-out-kit/75883

and probably fit it on the right hand white down pipe

Honestly I'd get a plumber to look at it - we have a similar set up (without the washing machine) and the dishwasher drains into the sink u-bend thing... Its annoyingly loud as it echoes up the sink plug hole! (The idiot kitchen fitters took out the separate drainage which used to be there and when we have the kitchen re-done it will be reinstated!!)

Either of the two white vertical pipes would do a job. Kit as linked to above will do it for you.

The white u bend on the top right of the pic looks like there might be a connector that screws off that you could connect the dishwasher into?
