Is your washer waste pipe just shoved into the large outlet hole behind your drawer pack?
If so you need to find some way to seal it off to stop the smell backing into the kitchen as there is no U bend on this and just goes straight to the sewer. Hence the smell
We have 2 plastic bags "stuffed" round ours to seal it and it works well.
If you don't use your apartment very often then this is a common problem.The U bends on Spanish sinks and loos are not that good and dry out if not used for a few weeks. The loo, shower, bath and sinks need water running through them at least once a month to stop the water evaporating and allowing the smell to come back up round the trap.This is not just at Roda - it is on all Spanish property. Our old Spanish house has an old granite wash sink in the garage with no U bend and the smell out of that can get pretty mean! :(
Do you have a property manager? If so make sure they are doing this. If you don't have a manager then you need to get a friend to do it for you.
