|
My Isomac Rituale is dead. It started dying yesterday. It would flip my
GFI breaker as it heated up. MY solution was to replace the GFI, but
cooler heads prevailed.
I opened the machine and the insulators around the thermal fuse
(thermal cut out TCO) were brittle and powdery. I figured that was a
bad sign.
I will pick up a TCO today from Fry's (I read here I should get an
NTE-8181. Any other opinions?).
My two questions are this:
The TCO (in its insulating sheath) was sort of stuck to the boiler. How
do I stick it again?
And
Do I need some sort of high temp insulator to protect the spade
connectors or can I use electrical tape?
One more thing:
I get NO power at all when I put the TCO back inline. Is that
consistant with the TCO being blown, or do I have a bigger problem?
Thanks,
Danny (no espresso. Bummer) Joe

There was one other insulator that was bad.
Good advise. I am in no rush. I love espresso, but I don't want to kill
myself over it.
Looks like a rebuild is in order.
Thanks again to all.

What is the temperature on the side of the blown TCO?
A replacement TCO with the same trip temperature should be used.
http://www.nteinc.com/specs/8000to8999/pdf/TCOs.pdf
If it were my machine, I'd be most concerned with powdery insulators
as this is indicative of a very high internal temperature. Or crap
components that should all be replaced. Are only the connectors to the
TCO powdery or are the others suspect?
Don't be too hasty to get the machine back on line. Solve the problem
that caused the issue in the first place.
Good Luck!

And a simple, but good crimper will be fine -- you aren't going into

Probably not as expensive as a new machine...

For fully insulated quick disconnects, Molex ETC with the extended
sleeves are also very good. NewarkInOne has OK prices on these, but
they are still $$$$$$.
Use a good ratcheting crimper with dies that crimp the extended sleeve
as well.

Fry's generally carries crap, but try to find name brand stuff -- 3M,
panduit, etc. an electrical supply house is better.
over time the insulator can get crispy from heat. heat from the boiler
-- normal or heat (resistance) from faulty connections -- NOT normal.

Yes, it does. Thanks, Dave.
Will Fry's (or similar) have the necessary connectors and insulators?
It was disconcerting to have the plastic (nylon?) crumble in my hands.
I imagine it was because of the heat.

Isomacs -- even new ones -- have quality problems with the crimps on
the push-on connectors!
CHECK every single one in the machine. -- try to pull the wire out of
the crimp, and make certain ALL are very firmly gripping their male
connection(s).
cut off and Replace any that are loose at all. Use GOOD connectors
and the proper tooling. Never use tape.
hope this helps.
