Subject: Isomac tea, broken machine or broken user?
Hello,
I've won a Isomac Tea espresso machine and are having some problems to
get it up and running.
The problem is that I don't get enough pressure while making the
coffee.

I haven't yet tried with different kind of coffee, but I bought a
normal espresso coffee (Lavazza Espresso Nero). I use the single cup
portafiller and put about 1 full spoon (the spoon that came with the
machine) and press with the tamper firmly.
With this procedure I get 2-3 bars and a "lipton-style" espresso. The
water runs out directly (as I've understood it this should take 20-25
seconds).

The pump pressure (the meter on the left) is at 1.2-1.4 which should be
ok according to instructions.
I let the water run for a while so it's hot and I get steam of the
steamer. The water does not fell burning hot though. When the coffee
button is down the pressure is about 4 bars. The green light is on as
it should. And I've RTFM that btw seems to assume that one already has
a couple of professional barista years of experience.

Do you think it's broken or may it work with another bean or is it me
that do something wrong?
Since I won it I might have some problems finding warantee/support even
though it should be possible in some way.

B.r.
Johan

Today I tried with coffee grounded by a shop only 15 minutes before I
used it and the taste and behaviour was something completely different.
Now I get the pressure that I should get and I guess I will learn how
much coffee to put (I had to restart on my first attempt because
nothing came out :-) ) and how hard I should press with the tamper
(which in the end seems even more urgent to buy than a grinder, that
plastic thing is completely useless), and how to keep all the
components hot enough.

Thanks a lot for your help

Kia ora Johan,

Preground coffee of this type is designed for inexpensive machines - -
which require a coarser grind than a good espresso machine, such as
your Tea, does.

If the grind is too coarse, water will flow straight through the coffee
with little resistance, as you have observed.

If you are going to get a shop to pregrind, make sure it is much finer
than what you bought. This might help you decide if you like coffee
enough to commit the extra money and get a grinder, or if you should
let the Isomac go...

THAT is a GREAT analogy!

If you intend to use preground coffee, sell the machine now. If you
intend to drink actual coffee, buy a commercial quality grinder.
Calling preground "coffee" is like calling a pile of rust "steel"

Not only is that description entertaining, it is, to a great extent,
scientifically correct. Grinding coffee and allowing it to be exposed
to air (even for a very short period of time) causes oxidation to take
place which stales the coffee. This is exactly what happens to steel-
add oxygen and it becomes iron oxide (rust). Nice one, Jim!

Johan,

Please be aware that the machine you have (the Isomac tea) is one of
high quality that sells for over $1000 now for the current model. A
great many people on this group would love to have a machine of that
quality and performance! It is one that is capable of making excellent
espresso when operated and fed properly. It will take some practice to
get the most from it, but for now, to get the best from this machine's
potential I would highly recommend finding a local source of freshly
roasted coffee that looks brown and not black, and does not have a lot
of oil showing. preferably blended for espresso. Along with that a
quality grinder is a must. Look at the mazzer Mini, the Rancilio
Rocky, or the Nuova Simonelli MCF. These grinders are at the "bottom
end" of those which are best suited for making espresso. They may seem
expensive, but will last many years and make lots of great coffee.
"lesser" grinders have less adjustability and smaller burr sets which
will not last., They also have lost of plastic that will not allow the
precise grinding that is needed for espresso.

Hi.

not in any particlar order:

1) You need a GOOD tamper
2) You need freshly ground coffee -- grinder?
3) Throw AWAY the single shot basket.

but you need to do all 3 at least.

check back! thanks!

Hello again,
thanks a lot for the quick replies.

To specify, yes, Lavazza nero is supposed to be preground for espresso
machines.

I'm going to buy a grinder but I thought I at least should be able to
do an ok even if not excellent espresso with pre-grounded italian
espresso powder.

However, it sounds like I should go to my local coffee store and make
them grind some for me so I can continue my troubleshooting from there.

It should be close.

Ask if you can grind a pound, but into different bags, each at a slightly
different grind.

I'm unfamiliar with this coffee. Is it preground for use in espresso machines?

Your gauge and your observation are in sync, both are saying the pressure is
low, but the flow is high. If the machine is perfect, the only remaining factor
is how fine the coffee is ground.

Switch to the double cup and see if your results are different.

That is the boiler pressure gauge.

People pull shots differently, even on the same type machine. Yours is an E-61
head, which overheats when idle for about 20 minutes. What you do is run water
through the head until the hissing stops, then count to 6 seconds. This will put
the water in the right temp range. Mount your PF. Wait for the green light to go
out, then pull your shot. YMMV.

You __NEED__ a good grinder. It sounds like you are using preground
coffee, and that makes it VERY (extremely) difficult, if not
impossible, to make espresso. Be prepared to spend $200 or more for a
good grinder if you are serious about the machine.
