Sad to hear, but not too surprised. My Elizabeth only had a small problem with steam wand with a slight deform teflon tube clogged one hole. Took me long enough to fix it. Lelit almost hit a home run with Elizabeth but they also seem to have made some bad decisions and used cheap parts where it is more likely to fail, like the steam valve.
For Americano I just use the kettle. Way faster and easier. I do draw the hot water from the steam boiler but only to warm up cups
