  • Hi I am new here
Hi,  when I hear my Silvia up to steam, steam comes out one of the tubes and bubbles into the water tank. It’s regularly descaled and backflushed. What is wrong with Miss Silvia?

Welcome mate.  Is your return valve stuck open???  Scale?  Time for a service!!  If you don't like the idea of electricity, water and lots of conductive metal perhaps it's a job for a pro.  Better to have the machine offline for a bit rather than you or a family member.

    • hey brew coffee to you!
agreed I get my equipment serviced once per year whether it needs it or not in the end it's cheaper to service than it is to replace or repair!

Yes, certainly sounds like service time.
