Howdy Terry!
Wow, that's the best explanation I've seen to date of why the ES-1A had such
a poor reputation. Thanks for the insight. Your comment about them often
being installed without a calcium filtering system was 100% correct - a
problem that still exists all too often. Last month I took a look at a
coffee house & their machine problems. Looking around I see a nice GE water
softener that someone had bypassed. When the systems were installed it had
two water paths; the normal one through the WS and another that bypassed
it when maintenance was needed. The bypass system operated manually via a
three-way valve. The valve was turned to deliver mains water to the
machines. I asked the owner if he'd been having problems with the WS system.
He said no, it's working just the way it has since the plumber installed it
three years ago. It seems the plumber had never switched the water over to
the WS system!
No, I'm not surprised that machines are screwed up by poor tech support - in
fact I don't understand why owners let them get away with it as much as they
do. One thing I do is educate the owners about how to take care of their own
machines, eschewing tech support altogether. Since this is my hobby and not
my vocation I'm able to spend more time getting the message across than a
service tech could afford to.
BTW; the hose clamp around the boiler is a source of several running jokes
among ES-1A owners. Susan Matthewman just took possession on an ES-1A that
actually has the hi-limit tstats attached to the boiler as they're shown in
the parts list manual. That's the first one I've seen (of 15 that I know of)
that didn't use the clamp (which actually does a good job) to secure the
tstats.
Thanks again for the perspective!

Post by Coffee ContactPost by Jack DenverDavid is of course correct - I have no personal experience with these
machines but I respect the word of that poster (Terry M) - you can
search the archives for ES-1 and see what he had to say about them. It
was not favorable.
The machines are, as the others have pointed out, really products of the
Gaggia Spain company , maker of Futurmat, Italcrem/Visacrem, etc. (and
for decades un- affiliated with Gaggia of Italy - if anything the parts
resemble Faema more than Gaggia) It may be that these machines do not
stand up well to the long term rigors of full commercial service but are
adequate for home use.
The ES1-A is probably the best machine that Bunn sold and was one of
the first commercial espresso machine I owned. Since then I have had 4
others (taken in trade). I have repaired dozens of Bunnespress and
scrapped almost as many. There are still two in service locally at very
low volume locations. One of the 'Starship Enterprise' groupheads lives
on my desk as a paperweight.
The Bunn espresso project was a complete disaster. The machines were
sold by restaurant supply houses, usually installed with no softener by
technicians who knew nothing about espresso. When the machines broke the
customers were given no warranty because of 'scale damage'. After a very
short period of time Bunn dropped the line and quit stocking parts leaving
their customers 'hanging'.
The machines themselves are probably no worse than other low-end
inexpensive Spanish machines. The water and steam valves are tiny 'pin
and ball' type which fail very often (but are easily repaired) and are
connected to the boiler by a silicone tube (not Teflon). The check valve
is very lightweight, The electronic boxes failed much more frequently
than those in the Italian and French machines and were much more
expensive. The hi-temp cut outs seemed to be an afterthought, held onto
the boiler with a giant hose-clamp.
I have always suggested that rebuilding a small commercial espresso
machine is a worthwhile project for home espresso enthusiasts and have
helped many alties with their projects. If someone finds a lightly used
ES-1A needing no repairs they might be pleased with it for the home.
However looking at the long run I would advise choosing another machine as
a 'project', better to put parts and labour into a quality machine that
will survive long enough to become a 'classic'.
