Thank you Kathy and Patrick.
I just got off the phone with Maggie (WLL tech support), who was extremely helpful. I am going to ship the original machine back and WLL will send me a new one. Ill give the new one a try and fingers crossed steam system will not smell like the old one!
I bought my brother a Classic a few months ago, which he is very happy with, so if the second Twin does not work for me, perhaps I will have to revert to an option similar to yours Patrick.
Thanks for the responses.
