Find the cause first.

You could try giving it a through clean get some washing soda put a couple of cups in the sink and hot water mix well let the sink drain slowly via the sink plug this is user friendly and far less hazardous than acid based drain cleaners, a build up of food waste and washing machine gunk can cause these smells if this does not work then it a strip out and replace it job . cheers kop

even thought it's apparently not the issue here, you still need to make sure the WM pipe rises up above the sink overflow height before it falls to the trap connection, otherwise when you empty the sink the dirty water will stagnate in your washing machine sump.
Is it worse in certain wind conditions? If it's always constant it's something festering in your pipework, if it's affected by the wind it's coming through from the drains.
Agree with removing the boxing. If everything else is ruledout. There ould be a redundant connection not blocked off.

Hi,
Not sure what you mean abot the WM waste and the sink overflow?

 

[Diy592]

Picture of WM waste.

Ok, So I got into the boxing today and all is dry no leaks or anything.
Connections seem ok. It is drafty in there though?

 

[Diy592]

The smell is not constant.

It looks to me like its from the washing machine as your connection is not looped high enough and is above the water trap letting the smelly water in your grey w/m pipe release to atmosphere. Also it could be the pic angle but pipe after trap looks like it goes up hill for a bit

Ok so been looking into this further, took off WM waste and DW waste and there was no smell.

When I opened up the boxing to the stack there was no smell.

But when I took a shower that go’s into a separate soil stack the smell returned from the kitchen stack?

assume you checked round the back for missing blanksb
Could be a hole in another floor that's blowing up through the gap. On a neighbour's floor you can let them know. But if you block the holes in the floor it would help
