My 2 1/2 yr old Silvia is leaking a steady stream of water from the solenoid drain tube during brewing. This has just recently started. She leaks a couple of drops during steaming, but there is an excessive leak during brewing. Is this an indicator of solenoid valve being faulty? Any other thoughts or solutions?
Hi
The solenoid valve needs back flushing the correct way with a espresso machine detergent like Cafiza, or Joe Glo. Place a 1/2 teaspoon in a blind basket. (don't come with Silvia). Place blind basket in portafilter and brew like making espresso, but run pump for no more than 5 to 10 seconds or until the pump starts to change tone (slow down). Stop the pump when either of these things happen or Silvia can be damaged. Repeat the pump 5 to 10 times leaving a 1 minute wait between cycles, or the suds comming out the 3 way valve turns pure white, with no coffee stains in the foam. Remove the portafilter and rinse then reinsert and repeat the cycles to rinse the internals. This should take care of the problem. If not you may have to replace the 3 way.
