Subject: Isomac machines-- Always interesting
Isomac espresso machines often present with interesting quality or design
issues.

Example: A 10 month old "Tea" in here for a brain transplant.

The SSR that controls the power to the heater is found mounted with only 1
screw instead of 2 and NO heat transfer compound.

I just do not get it! all that would be needed is:

* one more hole drilled
* another small bolt and nut (and as a bonus, a lockwasher, maybe?)
* a dab of heat transfer grease

Total cost about 15 cents or so.

This may be tthe company that touts no teflon hoses, etc.

BUT they ignore things like cooling for critical parts, and crimping
connectors.

May I advise owners of Isomac HX machines to check this out?

Never, EVER, encourage a spammer!

What I wouldn't give to see what MP would say in this situation.

Great coffee, complete rewire in the first 18 months of owning it.

The Tea (and Zaffiro) remains my favoirite no non-sense E61 in design,
especially the angled switch and dial panel at the top, a home machine
designed for kitchen counters and not fantasy cafes.

Agreed, my Zaffiro produces great espresso, although the recent batch of
bulb, brewing stats are a dead loss. The old stats, black body, Italian
made, had a deadband of 5 mins. The new ones, brown body (made where??) have
a deadband of 10 mins. Ok, this may be a prob with the euro version (230v
supply) but agent awaiting reply from Isomac.
I'm a candidate for PID - if I knew how ........

Hi Dave

Your Prodigy stat arrived this morning - many thanks indeed, much
appreciated. It seems identical to the prodigy supplied with the Zaffiro,
when new 2 years ago. The t/c probe that drops into the boiler pocket, is a
slightly different design, but is the same length. There is also one added
feature, your Prodigy has a calibrated dial (up to 120C). The original one
had just a bare slotted spline, I guess Isomac didn't want anyone adjusting
it from the factory setting.
Throughout the day, the Prodigy has given a steady 5.5 mins deadband, which
is a lot better than the 10mins deadband I was getting from the Tepcon stat,
supplied 3 weeks ago.
Once again thanks.

Bertie

Talk to Andy S he'll PID anything, or maybe you should just PID your
espresso machine.

If there was a DIY kit and/or plans available for the Zaffiro, I would PID
it myself.

DIY the DIY. It is _NOT_ that difficult.

RS in the UK should have most of the stuff.

A little uncommon sense and you can translate from a Silvia to
Zaffiro.

Sorry Bertie, i was taking the Mickey. Perhaps your espresso machine would
be a better candidate for PID.

Your from the UK? heck you shoulda got that.

If you can replace a pStat, you can PID your machine.

It's only a couple of hours work once you've got all the bits.
http://www.ielogical.com//coffee/VBMPID.html has lots of picture links
and few words. Some say it's a clean install.

shall has a page on his bionic Zaffiro with lots of words.
http://home.earthlink.net/~mrfuss/

Just don't mount the PID inside the box. ~<:-(
AND don't buy a used PID!!!!

The original stats were tight but not reliable; the new ones are
reliable but not tight. DaveB does very nice PID installs (despite his
posting style), if you don't want to DIY it.

It's quite possible that the newer Tepcon stats may have a longer life than
the old Prodigy ones, but 10 mins is too long a deadband. Not a problem if I
light roast some Centrals, as I prefer the taste of these at the hotter end
of the cycle. With the darker roasted Haraars, MM's and OBJ's, I like the
cooler end of the cycle. I can shorten the d/band by pulling 4 fl oz, but
it's a bit of a fiddle and not very accurate.

The first replacement stat had a deadband of 15mins ... that went back.
I'm not fooled by Dave's wacky posting style, he's not wacky enough to pay
the shipping on 20Kg to the UK :)

Dave I've often felt that the local agent irons out a lot of wrinkles
and that eventually these would find their way back to the factory to
be taken on board. I've yet to meet a small or commercial machine
that is perfect out of the box.

I've got some tea V 2.0 machines and brew pressure was 15 out the
box. No biggie there, the biggie to me was that the body panels are
real buggers to put back on. Sometimes self-tappers make life a lot
easier, I've spent an hour this morning trying to get the body to line
up with the frame to get the threaded bolts through. makes good
coffee though.

At least they improved form 6 years ago, they use to attach the relay
with double stick tape...... i'm serious instaed of dissipete the heat
it was insolated back to the
realy.........................................
