I am told it is "not correct" for a washing machine waste pipe to exit directly behind a washing machine. Why is this? Are there any issues about the washing machine waste emptying via the sink trap. I am concerned about the rate of Water discharge.
Washing machine waste pipe position

It's perfectly correct...
Both stand pipes and sink traps work fine IME.
If you've got the space, I can't think of a reason.
I have my washing machine (and dishwasher) waste connected to the sink waste. And it empties at quite a rate from a pump in the cellar. I think it's just a matter of time before it pops the push fit pipework. So in the course of time, I will install a dedicated washing machine waste. Before it's too late. Or maybe just after - haven't decided yet.
Also, and I'd guess that this is because there's a fair amount of water sitting in the 22mm/10m pipe between washes, it's quite smelly - so it'd be an idea to to route the washing machine waste after the sink trap.
