Removing top cover of Magic Deluxe
for replacing internal
parts
The steps detailed below apply to Magic
Deluxe, Magic Comfort Plus & Royal
Professional.
For parts location in the machines,
please use exploded diagram of the models, made
available on this web site.
Removing the top
cover is easy if proper tools are
available. Specific tools include
1- Torx
screw driver (star shape screw head instead of Philip
head)
2- Philip screw
driver one long and one
short 3- Nose Pliers 4- A
test meter (analog or Digital)
5- A small
magnet that is strong enough to pick weight of a
teaspoon. 6- A 1/4" plastic tube, 3 to 4
ft long. 7- Vacuum cleaner with narrow long
nozzle.

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 cover.
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
surgery.
To find leaks, machine has to
be operated. To operate the machine with the
top removed, water connection has to be
established and the water level sensor activated.
To connect
the machine with source of water, separate the silicone
hose from water inlet. (bottom rear of the top
cover). Connect the 1/4" plastic tube
by inserting it into this 5/8 mm 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 water
container.
Place the magnet
next to the water level sensor. The level
sensor 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 electric outlet. If so, the position
of the magnet can be jigged until the no water water
light goes off.
Close the door
with brew unit in place. Insert drip tray and the
dump box in place correctly.
The machine is
now ready to be powered up and tested.
Immediately
after turning the power on, prime the machine by opening
the steam knob. Protect the electronic
board from steam or stream of leaking
water aimed towards it. Once warmed up,
the machine can be tested by making a
fake espresso (pre-ground cycle without coffee) to
see if any leakage of water or steam can be
spotted.
With the top
cover removed, the following internal parts can be
inspected for leaks and functional faults. Replace
faulty parts as necessary:
a- the
thermostats mounted on the heat exchanger.
b- the heating element
c- the solenoid
valve coil near the pump.
Subsequently,
before replacing the top cover, make an espresso with
coffee. To do so, hold the bean hopper on the grinder
inlet and add beans in the bean hopper just enough
for one espresso (excess beans will spill around
and inside and be difficult to
clean, especially from around the doser
assembly.
To remove the
pump, avoid removing the pump mounting pads. Disconnect
the 90 degree plastic connector with hose, from the rear
of the pump. Make sure to remove
all old O-rings and clean space around o-rings.
To connect hoses, slide O-rings on the hose end
first, and wet new O-rings with lube, before
inserting.
Replacing
the O-rings will be much easy if the heat exchanger
is removed 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 exchanger 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.
