I have the exact same setup in the laundry
So my question is can i get some sort of pipe diameter reducer to make it the same and plug the washing machine hose up in the same manner as the dishwasher???
At the moment i just have the washing machine waste hose going into the laundry sink

Have had that plumbing for 47 years (and 3 washing machines), which seems reasonable.

Will it put more pressure on the washing machine pump if you reduce the outflow diameter? I imagine the washing machine is pushing out a fair but more water than the dishwasher.my brother fixes washing machines for a living, currently sitting beside him so I just put the question to him....in a nutshell, it’s not good for them....one thing he mentioned was regarding the hose being designed to sit inside a hole and something about it acts as an air break and it then not being able to siphone water back into the machine...and then he mention the pump is the size it is as it’s suited to pumping X amount of water through X size hose. He said sometimes you might get a way with it working, but he’s had several machines not working properly he’s been called out to, and that type hose set up was the issue.

This is something new. See if the link works

Hi,
That looks just so much better than what I put in, but it was back in 1986 and hasn't failed yet.

That would be my concern as there would be the chance that it would siphon down to the spigot level.
Not an issue for a dishwasher as they only have a bit of water in the bottom, but a washing machine machine may never fill.

The outlet pipe from the pump has a hook support that lifts it above the max water level, then it drops to the spigot.
When water is pumped out, it goes up and over, yes, a syphon would form at this point, but it breaks when the pump runs dry. So no problem.
As mentioned before, I have used this system on 3 machines, 2 houses, since 1971.

The spigot is before the S bend so the sink plug hole so would also create an air gap. Unless the sink is full of water.and my guess is, when you empty a sink full of water it likely has the chance for the pipe to fill above the S trap and then that to go back up the spigot...don’t have the hose go heaps higher then the sink hole and there’s the opportunity for dirty dish water to siphone back into the washing machine. I have no idea if it really does or how much, all I know is my brother who has fixed commercial and household washing machines for the past 25 years mentioned it when I asked him...so reckon there must be some merit in why he said it.

That would be the case if the hose was not looped high enough (it is above both max sink and machine water levels).
It is a laundry sink, so dirty dish water is not part of this plumbing.

Hi,be the same case with dirty laundry tub water also...seen plenty of stuff being washed in laundry tubs (paint brushes etc) over the years that wouldn’t want mixed in with the washing.
