Removing the top cover: To remove the
top 1- Remove water tank.
2- Remove two philip screws to
lift the bean hopper out.
3- Remove the grind
adjustment lever. For the grind adjustment lever place your two
index fingers below the bottom of the lever and pull up from both
sides. (Check instructions for adjusting and cleaning the grinder
illustrated instructions on the web site).
4- Remove two Torx located
on the rear edge, under the water tank.
5- Remove two philip screws,
one on each corner in the front, below the front edge of top
Pull the cover up by lifting
it about 1/2" from the back and moving it to the front to free it
from the steam knob and the touch pad. Lift the steam pipe to its
top to slide it out through the slot as you free the top
cover. A wire connecting the hot plate with electronic
board will still be attached and will limit the complete removal of
the top. Do not disconnect the wire. Lay the top towards the back of
the machine. Now the entire machine is exposed for open-heart
To find leaks, machine has
to be operated. To operate the machine in this
condition (top removed), water connection has to be
established and the water level sensor activated, to cheat
the electronic circuit board to sense the tank is in place with
To connect the machine
with source of water, separate the plastic tube from its connection
to the water inlet from the tank(bottom rear of the top
cover). The other end of this tube connects the Flowmeter with
an in-line filter in between. Connect the 1/4" plastic
tube by inserting it into this soft silicone tube on one end and dip
the other end of the 1/4" plastic tube in a bottle with clean water.
Make sure that the tube stays immersed deep into the bottom of
the bottle and held with a plug to prevent it from slipping above
the water level inside the bottle.
Place the magnet next to the
water level sensor. It is a white rectangular piece (1' x 1/2" x
1/4") located between the water tank and the grinder. If the magnet
is not properly placed next to the level sensor, the no water light
will be on when the machine is plugged into the lectric outlet. If
so, the position of the magnet can be jiggled until the no water
water light goes off.
Make sure that the door is
closed with brew unit in place. The drip tray and the dump box are
in place correctly inserted.
The machine is now readyto
be powered up and tested.
T operate the pump, turn the
steam knob open. As the pump works, any leakage can be noted
immediately. Protect the electronic board from steam or
stream of leaking water aimed towards it. Machine can be
testednext by making a fake espresso (without coffee) to
see if any faults can be spotted.
If no leakage is detected,
the following components should be checked if any one is
a- the thermostats mounted
on the heat exchanger.
b- the solenoid valve coil
near the pump.
replacing the top cover, make an espresso with coffee. To do so,
hold the bean hopper on the grinder inlet and add enough beans in
the bean hopper for one espresso (excess beans will spill around and
may fall inside the machine and doser assembly. That can be a
problem later, and also be difficult to clean, unless a vacuum
with long & narrow nozzle is available to remove beans from the
bottom of the machine and around the doser
With the top cover removed,
the inside parts can be inspected for leaks and replaced as

is $55.00 and the O-rings
(NM02.028) are two for each Teflon hose going into and coming out of
heat exchanger; and 2 O-rings in the Teflon hose connection from the heat exchanger to
the steam valve. There are two O-rings where the steam pipe connects
to the steam valve and two in the hose coming out from the
To remove the pump, try to
avoid removing the pump mounting pads. Disconnect the 90 degree
plastic connector with hose, from the rear of the pump. To reduce the front-end
length sliding out of the mounting pad, you may try to remove the
pressure release valve. A brass fitting, which is not a part of the
pump. There is an O-ring at that joint which does not go bad as it
deals with cold water only. In any case I will send you one. All in
all there will be 9 O-rings at $1.25 each.
Make sure that
you remove all and as many old O-rings as the new ones indicated
above. Wet new O-rings with
lube before inserting. New O-rings will slide in
the O-rings will be much easy if you removed the heat exchanger from
the machine. The heat exchanger is mounted with only one bracket and
two screws. You will need to disconnect wires going from heat
exchanger to the electronic board. Before you can pull it out, you
should make copious notes to remember each wire disconnected from
the heat excnager or the electronic circuit board. There can be no
directions from anyone
in that department if you end up with a lose wire and do not
know where you pulled it from. In such a case the only way is to
follow an electrical diagram.
