Subject: Silvia- I think she's getting weaker.
|
My silvia is the bomb. At least she was for the past 5 years. Now she
isn't rocking my world.
She can't seem to make espresso in reasonable amount of time, lack of
pressure. I don't know how to isolate the problem, I think its the
pump. I am not even tamping and it hardly pushes anything through.
I backflush every few months, clean all the shower screen etc. Is it
difficult to replace the pump ( I am not an electrical engineer)? I
bought a pressure gauge for the portafilter but can't make it work.
Now it is extremely loud, and when I try to use the steam wand for
water it doesn't push water or work so well and there is no steam tip
on it either (see below)
I recently tried replacing the steam tip, the threading inside the pipe
broke when I was unscrewing it, and suggestions on how to get it out,
other than replacing the entire steam pipe.
Thanks,

No -- easy! Small crescent wrench is about it.

Nope you need a new pipe if the threads are busted off

You've eliminated the possibility of scaly boiler/pipes?

It is. But I also wonder if that could be pressure related since there
is nothing coming through the portafilter, but sometimes leaks through
the sides.
How do I clean the solenoid coil? or worse case scenario replace it.
Also, do you know how to use one of these pressure gadgets for the
portafilter.

You can disassemble & clean the VALVE, see
http://member.newsguy.com/~jenkins/silvia/, but when it comes to the coil
replacement is the only option.

Often a symptom of solenoid coil problems. Is the 3 way valve leaking during
the shot?
