That is interesting. We have the same machine, which now concerns me. However due to recently removing on some old paint which we later suspected might have been lead based I Thad some blood tests for lead levels and everything was fine.
Just get an Ascaso Steel, it's a far better machine anyway :) It was a significant upgrade from my Vibiemme Domobar, which already was a significant upgrade from the Silvia. Not just espresso quality, there the upgrade (from the Domobar) is mostly greater consistency and the ease of getting the best outcome with less experimenting, it also uses significantly less resources - much less energy and also much less water. The only small complaint I had was that I had to keep my finger on the activation switch because I find the automatic flow-control useless (too inaccurate), until somebody pointed out I could program it to measure a huge amount of water that I would never reach in practice and then I could use it as on/off switch for drawing the espresso.
