Subject: Cimbali shorted, need to ID part
Turned on the Cimbali Jr. last night and when I pulled a cooling flush
I realized something was wrong by how the water flowed out. The
machine was stone cold. Pulled the covers and found a short on one of
the heating element wires. This wire comes in from the connection
block. The other wire comes from the P-stat, it is the hot. All fixed
and pulled a shot as normal.
My question is this, the small piece that the wires connect to
resemble a non-resetsble high limit thermostat. It is round part
ceramic and has 2 tabs that stick out horizontally that get screwed
onto the back of the element. Then it has 2 ears that come out the top
were the hot wire from the P-stat goes and the common /neutral goes.
Is this correct? While rebuilding the machine this piece appeared fine
and I never gave it much thought. It appears to function fine, so I am
looking to get a spare and to figure out what it is?
If it contributed to the short in some way then it must be replace.


thanks,
p

Hey Ken,
I had a generic one in my hands and can't say for sure what
modification it would need to work on the Cimbali. Other then the tabs
sticking straight up, it looked identical as I recall. Any idea what
mods a generic one would need? Sorry for the long delay, I was away
and Google groups seemed to be down.

I really don't know; the modifications are to make it FIT, not on the
temperature side, if my memory is correct. I remember discussing it with
Michael or Angelo of espressopartsource.com a while back, but I have
forgotten it. Unless you are dealing with someone who knows what they are
doing (and Michael/Angelo are very good examples of people like that) then I
think you should just buy a Cimbali OEM or knockoff version of the part and
leave it at that.

Safety devices are there for a reason and I'd much rather pay $20 more than
have a fire in my house because I thought I knew what I was doing and
decided to wing it to save $20.

I believe this is in fact your one-time-use high temperature limit switch.
You can either try to get an OEM Cimbali one, or you can get one meant for
other machines that has been slightly modified as long as the target
temperatures are similar. I got an LM knockoff one (modified slightly) for
my Junior from Michael and Angelo at espressopartsource.com They knew what
they had to do to make it work in a Cimbali. Or try to get a Cimbali one.
Odds are you will never actually use it, however. Other than for emergency
use, I would not use the machine with one of these switches burned out and
bypassed.
