The Coffee Machine

My new/old Rimini arrived a day ago and I’ve been inspecting it.  I haven’t had the opportunity to hook it up with water and power yet but I’m getting close to that eventuality.  In the interim I have a question about the knob on the lower left front of the machine in this picture

When I turn the knob, the knob mounts solidly on the shaft of the valve but when I turn the knob, it doesn’t stop, in either direction.  It just turns and turns and never hits a stop.  Is there something wrong with it?  And what exactly does this knob do?n  What about the galvanic corrosion I see on the valve, should I be concerned?

Please pardon my ignorance.  I’m learning aobut this machine, and I’m truly enamored with it.  BTW, when I wrote to you about the Bunn Users Group, I believe I said the Bunn ES-1A was a USA only machine but it’s come to my attention that machine was marketed elsewhere in the world as the Milady

Hello Andrew,  Thank you so much for sending me the parts file and extending a helping hand.  The parts file will come in very handy, especially when I disassemble the group for a thorough cleaning.  I spoke with the PO yesterday by phone and he told me the machine was last used in 2004 and not 2002 as I mentioned in my email to you.  It’s still 4 + years since it last ran and I have no idea if the machine was maintained properly with detergent backflushing (owner of the machine used hired help to opearte it and seemed clueless about upkeep)

A couple friends of mine run a Yahoo group for Bunn ES-1A owners-

http://groups.yahoo.com/group/BUG-is-Bunn/

I suggested to Tex (Robert Harmon) that he invite you to join.  His reply was you are most welcome to join and he asked me to invite you 

As the name implies, BUG is an acronym for Bunn Users Group.  You are probably aware that Bunn Coffee Co in the U.S. had Gaggia in Spain manufacture a one and a two group espresso machine for Bunn with Bunn’s name on the machine.  I think production ceased in 1996. 

Anyways, Tex and David Mankin started this group to be used as a resource for Bunn espresso machine owners.  Since machines like Visacrem, Futurmat, etc. were built in the same factory, those machine owners are welcomed too.  I think there is only one other Futurmat member there

It is an international group and I’m sure the group owners would like to see it grow.  Having said that, they limit membership to owners of the machines.  Anyone can peruse posts but members have access to the other areas of the site like the files, photos and what not

I’ve only recently been allowed to post w/o moderation now that I will be taking possesion of one of these machines shortly.  FWIW, I met Tex when I purchased my Gaggia Classic from him last spring.  He’s been a good friend and has taught me quite a bit about espresso, home roasting green coffee beans and the like

That file you sent to me, I was planning on adding it to the Files section after I receive my Rimini next week.  I am wanting to surprise the others there with this machine acquisition and so I want to keep it under my hat until then so to speak 

Best,

Jim (Jake) Wilson
