Vibiemme Espresso Machine Overview
(pronounced "vee*bee*m*may") Below is overview of the heat exchanger version
only:
Super Best in Class! or in other words!
Creme de la Creme! There are many reasons why these are the
best blurbs for the Vibiemme line of Domobar Super. Although
'domobar' literally translates into 'home bar', 'super' was
added because this model has 'on demand' steam functionality
and because of the super reliability and super components inside.
The main reason we classify the Vibiemme line
up as Super Best in Class is because of reliability. 1st-line
has carried the line for a little over a year. With well over
200 units sold in the first year (sorry, we have to be conservative
in promoting 'units sold' to prevent our competition from raising
their eyebrows), our track records show that Vibiemme has
the lowest percentage defect rate for our customers in the first
year compared to all other machines we carried in the first
year. Our major problems with this line in the first year were
mostly attributable to damages from mishandling by our friends
at UPS and Fed Ex. However, these have been resolved with a
newer style packaging and removal of the feet during shipping.
The few problems we did have (three heating elements, one brew
pressure gauge, and four sticky vacuum breakers due to limescale)
were all handled by each customer with replacement parts so
that these heavy units would not have to be shipped. In fact,
our in house technicians keep asking when the first unit will
come in for repair.
The second reason that makes Vibiemme a Super
Best in Class is the design and components selection on
the inside and outside of the machine. Some of these actually
have not only added to the reliability factor, but also to the
cup quality of the espresso.
Although
the very first Vibiemme Domobar Super HX was sold to a Director of
the Late Show with David Letterman and we wanted to do a Top 10
List, we ended up with a whopping Top 18 superior design and superior component selection list as detailed
below:
- True Faema E61 grouphead - Vibiemme, in the early
'70s, became the offspring of Faema. Several employees left
Faema to start Vibiemme S.r.L. and at the same time, they
co-owned the patent to the Faema E61 grouphead. Up until we
started to carry Vibiemme, we always believed all similar
machines had a true Faema E61 grouphead. Were we wrong! When
you compare the groupheads of a Vibiemme Domobar Super and
a similar E61 espresso machine, you will automatically in
person notice the grouphead differences. According to Vibiemme,
the Domobar Super's grouphead weighs about 9 pounds while
comparable E61 machines weigh in at 7-7.5 pounds. Furthermore,
E61 groupheads made in Spain typically range in 6.0-6.5 pounds.
Less metal usually means lower cost and hence, lower price.
The decision for the greater thermal mass of the Vibiemme
grouphead adds to the temperature stability at the grouphead,
which typically results in a superior cup quality of espresso
more often.
- Larger boiler - The massive 1.8 liter boiler is
the largest you will find in this class of semi-commercial
reservoir only espresso machines. The larger boiler not only
adds to the temperature stability of the grouphead, but also
offers a greater amount of steaming capacity for larger home
parties and the office environment. Remember, super! Also,
since this machine has a larger boiler, it does require full-size
commercial grade steam and hot water wands. Some customers
have asked for the 'no burn' steam wands found on other machines.
The unfortunate part is that the teflon/vinyl hose placed
in the 'no burn' steam wands would restrict the flow of steam
from such a larger boiler. This would be a detrimental side
effect while entertaining at home or in an office environment.
In other words, the teflon/vinyl hose inside the steam wand
is like placing a speed restrict or on a Ferrari. Finally
with regards to the boiler, it is supported to the bottom
portion of the frame with a bracket.
- Wider diameter tubing to and from the heat exchanger
- Once you open the cover of Domobar Super, it can take a
while to find out what makes this espresso machine super.
It took us a while to figure out that the tubing from the
grouphead to the heat exchanger and back is a whopping 12mm
outside diameter (10mm by 12mm on the curved bends). This
diameter size is what you find on commercial machines placed
in coffee shops and other food service establishments. This
wider diameter tubing allows the heat exchange system to hold
more water for improved temperature stability and increased
flow of water in the heat exchange system. There is one manufacturer
(which we no longer carry) of espresso machines that have
6mm-6.5mm outside diameter tubing, and on these machines,
we have have experienced multiple issues with limescale buildup
at the tubing that enters the grouphead. All other espresso
machines we carry in this class have at least 7mm outside
diameter tubing and no problems, so far, with limescale ruining
the fittings.
- Three stage power switch - In ALL other machines
in the semi-commercial class (except for Pasquini, Bezzera,
and Fiorenzato due to a different technology), we have seen
heating element damage upon initial start up by the customer.
The reason is that the boiler (which is dry upon start up)
does not fill up fast enough upon initial start up. The result
is that the heating element melts and becomes damaged due
to this lack of sufficient water in the boiler. The Vibiemme
houses a three stage power switch: off, stage one, stage two.
Upon start up, the power switch of the Vibiemme Domobar Super
is placed into stage one. This is where the Domobar Super
espresso machine gets power to fill the internal boiler with
water EXCEPT the heating element does not receive any power.
hence, it can not melt down. Once the machine has filled the
internal boiler, the power switch on the Domobar Super can
be placed into stage two so it can deliver power to the heating
element.
- Micro switch under water reservoir - The staff at
1st-line are firm believers of quality micro switches underneath
the water reservoir. The purpose of the micro switch is stop
the heating element from damage when the water reservoir is
close to empty. We believe in the micro switch because when
it fails, it usually stops any additional internal damage
from occurring. In the category of semi-commercial espresso
machines, we do not believe magnetic floats for the water
level in the water reservoir are a good choice. We have experience
with magnetic float sensors in superautomatic (grind, measure,
tamp, extract) machines made by Spidem, Capresso, Saeco, and
Solis. In these cases, we have seen floats stick near the
top of their range due to limescale build up in the water
reservoir. Second, we have seen floats fail to float more
often than micro switches fail. In super automatics, a failing
magnetic float will not not cause heating element damage.
In the semi-commercial espresso machine class, a sticky magnetic
float can cause damage, mainly to the heating element. If
the float sticks in the up position due to limescale, the
machine believes there is enough water in the reservoir. However,
if there is really not enough water in the outside reservoir
and the boiler needs water to keep the heating element submerged
in water, the boiler's internal heating element will damage
due to a lack of water.
The Vibiemme Domobar Super line does not require a thermal
sensor on the pump. The purpose of a pump thermal sensor is
that in case a magnetic float fails, it will prevent the pump
from a meltdown. However, the heating element will still damage.
The bottom line is that micro switches do work the best, and
the Vibiemme Domobar Super has the most industrial micro switch
we have seen to date in semi-commercial machines. Some people
will complain they fail, and this is true when you pour water
on a micro switch. So, do not get water on them.
- Full size Sirai pressurstat and its access port
(Super HX only) - Many semi-commercial espresso machines (except for some
unknown reason Fiorenzato's Bricoletta line) suffer from one
common ailment - the pressurstat, otherwise known as the pressure
regulator of boiler pressure. The main reason for these pre-mature
failures is the small size of these pressurestats found in
semi-commercial machines. Since they are smaller in size,
they have smaller diaphragms which fail faster and they have
much smaller micro switches which build up carbon faster.
These pressurestats are namely Mater, CEME, and Jaeger. The
main reason why these small pressurestats are used is because
of the smaller casing used to make semi-commercial espresso
machines fit into your home or small office. Although these
smaller pressurestats are easy to replace and are fairly cheap
compared to the price of the espresso machine, changing them
is a hassle. If you noticed in the beginning of this paragraph,
Fiorenzato Bricolettas do not suffer this problem, but we
can not figure out why.
One of the reasons why the Vibiemme Domobar Super is larger
in size compared to other espresso machines in this class
is because it houses the full size Sirai pressurstat that
is found on the much larger commercial machines seen at your
local coffee bar, restaurant, or other favorite eatery. So
far, we have yet to replace the pressurestats on any Vibiemme
Domobar Super espresso machine. In fact, with the largest
boiler in its class, a full size pressurstat is most appropriate.
It is also well positioned near the top of the machine so
that you can remove the black port hole cover to change boiler
pressure settings without removing the body panels or top
cover off.
- Brain unit (auto boiler refill relay) placement
- When we met Vibiemme for the first time in October of 2005,
we advised Vibiemme that they needed to move the brain unit
farthest away from the boiler and at the lowest position possible
inside. The brain unit usually consists of two computer boards
covered on 5 sides with a sealed plastic housing, and the
last thing these boards want to feel is heat from the boiler.
Per our request, the brain unit was moved to below the water
reservoir in the rear right hand corner. This position has
the least amount of heat as heat travels upward. And, even
if you accidentally spilled water while pouring water in the
water reservoir, the electrical connections are facing downwards
so the chance of water contact is almost impossible. To note,
the Vibiemme line utilizes the best brain unit in the espresso
machine business - GICAR.
- UL Commercial Tested - Underwriters Laboratories
(a.k.a. UL) tests products for public safety. Although 1st-line,
like other distributors and importers, make recommendations
to manufacturers, no distributor or importer has the testing
facilities or technical expertise of stringent tests to certify
product safety like UL or ETL for the United States marketplace.
Both of these testing organizations typically visit the manufacturer
every three months to check that the proper components and
even raw materials are being utilized for your product safety.
The Vibiemme Domobar Supers have acquired a UL Commercial
listing so that these machines can also be placed into the
office environment. Please note the Vibiemme Domobar Super
does not have any NSF ratings required for commercial food
service establishments as this listing has not been applied
for by Vibiemme. The business reason is that food service
establishments should have a direct connection to the water
line for non-stop operation.
- Pump Position - One of the most common complaints
prior to 1st-line distributing Vibiemme Domobar Super espresso
machines was that the pump was very noisy. This problem has
been resolved prior to our shipments since we request that
Vibiemme reposition the pump slightly to the back and away
from the boiler. There were incidences in the past on these
machines outside the United States that the pump was touching
the boiler.
- Extension for three way solenoid valve - The three
way solenoid valve relieves the water pressure in the grouphead
and portafilter when the espresso extraction is terminated.
In out initial prototypes, we found excessive splashing from
this valve over the drip tray. We asked Vibiemme to add an
extension to remove all splashing, and they delivered on this
request with the very first units.
- Drip tray screen - On the initial prototypes, we
found the width of the screen to be on the smaller side. Upon
our request, Vibiemme has delivered the units with a larger
screen on the drip tray covers.
- New feet - All Vibiemme models have been upgraded
with elegantly appointed feet with rubber bottoms.
- Placement of two pressure gauges - Most machines
only have one boiler pressure gauge. The Vibiemme Domobar
Super has a second gauge which provides the brew pressure
reading during the extraction. Although we do not consider
the brew pressure gauge as 'extremely' important, we do consider
the placement of these two gauges near the top on an angle
of the Vibiemme Domobar Super to be important for easy reading
by the user. The reason why the brew pressure gauge is not
'extremely' important is that
- it can mislead the user to believe that 8-9 bar will
produce the best tasting espresso (yes, you can get bad
espresso at 8-9 bar)
- a superior indicator for a good espresso is the shot
timing, the visual of the pour, and ultimately the taste.
- Updated 02/02/2010 - we have learned
today that a competitor is mentioning how ''their' machine
has superior gauges because there is more metal. Although
they may have more metal, the gauges on the Vibiemme machine
are made of plastic - the main reason si that the metal
gauges absorb heat from the body of the machine whereas
the plastic will not. As for durability, we have only
replaced 10 gauges at the time of this writing. This is
hundreds of Vibiemme machines later and since April, 2006.
- Insulation Placement - The current manual and electronic
versions of the Vibiemme Domobar Super include insulation
on the inside of the wall between the water reservoir and
internal boiler. After much discussion with Vibiemme in Milan,
Italy, both companies decided to go this route of insulation
for a few reasons:
- Insulating the boiler would disrupt the natural airflow
inside the espresso machine. With an un-insulated boiler,
heat will rise normally upwards not only to pre-heat the
cups, but at the same time create an upward draft to keep
the bottom portion, where the electrical components located,
cooler. When the boiler is insulated, less draft is created
inside, heat build up increases due to more stagnant airflow.
This will ultimately affect the electrical components,
such as the smaller pressurestats and brain units (especially
when located very close to the boiler).
- Even with the boiler walls insulated, the stagnation
of heat will still affect the water reservoir, and
- For boiler insulation to become completely effective
in not allowing heat build up against the reservoir, all
the tubing inside should be insulated and an electrical
cup warming plate should be added. If insulation is added
to the wall between the reservoir and boiler, this will
only increase the temperature of the stagnated airflow.
These are the reasons why many manufacturers do not insulate
their internal boilers. We are in the process of acquiring
the insulation for previous customers. If you received one
of the manual or electronic models after December 1st, 2006,
you should have this insulation on the inside wall.
- OPV Placement - The OPV is known as the over pressure valve. This valve allows excessive brew pressure
water to escape back to the reservoir. The OPV is placed on
the cold water portion of the water line going to the heat
exchanger - this holds true for our other semi-commercial
espresso machines we sell. We also find this OPV to be the ebst found on prosumer machines. However, there are some competitive
models that have the OPV located on the heat exchanger right
off the top of the boiler. This is undesirable for two reasons:
first, the machine is potentially sending back hot water to
a reservoir that should have water as cool as possible, and
this, in our opinion, increases the temperature fluctuation
of the water in the heat exchanger which is used to extract
the espresso.
- Vacuum breaker valve - Vibiemme utilizes
the best vacuum breaker valve on their Domobar Super espresso
machines. These are less likely to stick due to limescale,
and they allow you to place this espresso machine on a timer.
Please make sure sure to read our power protection article
before putting any espresso machine on a timer.
- Timer - All Vibiemme machines can be placed
on a timer so that the machine can be fully heated for when
you wake up! There is a certain way to set this up so that
your machine's electrical components (any espresso machine)
does not get damaged by the timer. Timers can cause surges.
First, plug in your timer, then plug in a single outlet surge
suppressor rated 1080 joules or higher (this item can be purchased
in a local home improvement store), and then plug in your
espresso machine. The power switch can be left in position
II.
- Height - The Vibiemme registers at approximately
16.5" tall and fits under most cupboards. However, to
be able to remove the reservoir from this espresso machine,
you will need about 26" or more of vertical clearance.
The water reservoir is removed from the top of the machine
in the rear.
Due to the above top 18 reasons,
the Vibiemme line has offered 1st-line and its customers almost
perfect reliability. We hope you can enjoy these benefits by purchasing
a Vibiemme Domobar Super. We have also demo'd the Domobar Super
at the following coffee conventions to coffee professionals,
- Coffeefest, Washington, D.C. in February, 2006
- Specialty Coffee Association of America in April, 2006
- Coffeefest, Las Vegas in June, 2006
- Coffeefest, Seattle in October, 2006
- Coffeefest, Chicago, IL in February 2007
- Specialty Coffee Association of America in April, 2007
- Coffeefest, Atlanta, GA in June 2007
- Coffeefest, Seattle in November, 2007
- Coffeefest, Washington, D.C. in February, 2008
- Specialty Coffee Association of America in May, 2008
- Coffeefest, Meadowlands, NJ in May, 2010
The feedback has been tremendously positive, and
even the most keen service professionals and dealers have likened
the design of the Vibiemme Domobar Super.
The
Philadelphia Inquirer (page was removed at
PI) stated:
"Even these high performers were blown away, however,
by the gleaming chrome gargantuan of the Vibiemme ($1,500), a
retro- styled semi-commercial machine weighing in at 63 pounds.
With a computer board to monitor temperature, a big boiler that
transitions with no time delay between coffee making and frothing
(a major difference in some machines), and the option of going
fully automatic or manual, this was the luxury limousine of the
test. Its espresso was not just silky in texture, topped with
a swirling, multihued crema, it sang ethereal notes of fruitiness
and chocolate the other machines didn't produce."
Finally, 1st-line has partnered with a firm in Oregon
to handle all warranty and repairs for our Pacific Rim customers.

FAQ:
Q: I would prefer the Vibiemme Domobar Model
DS2BROELIN for the rotary pump, but right now cannot plumb in.
I've read where other rotary pump machines would work by just
inserting the water hose into a jug of water. Would that be possible
with this model? Thanks!!! Anthony
A: It is possible for the rotary vane pump to
pull water out of an external water reservoir, but we do not recommend
it as it puts more strain on this rotary vane (volumetric) pump
which was not designed to do this. It is better to get a Flojet
pump and have the water pumped from a 5 gallon water reservoir
to the espresso machine. Please ntoe that the user has to be very
careful in that a lack of water in the external reservoir will
not shut off the machine, and certain parts (rotary pump and/or
heating element) can become damaged (which is not covered under
warranty). |
