A reminder for any repair work undertaken using the following instructions:
Make copious notes to help put things back as they were. This is especially for
electric wires. Tag them, color mark, make notes and even take a picture or two.
(Instructions below are for handy or experienced persons only. Services

The following tools are required for removing the top cover:
1- Torx screw driver (star shape screw head instead of Philip head)
2- Philip screw driver (One long and a short arm)
3- Nose Pliers
4- A test meter (analog or Digital)
5- A small magnet that is strong enough to pick weight of a quarter.
6- A 1/4" plastic tube, 3 to 4 ft long.
7- Vacuum cleaner with narrow long nozzle.
8- Exploded diagram of internal parts 9- Wiring diagram
Removing the top cover: Steps to remove the top cover:
1- Remove water tank.
2- Remove two philip screws to lift the bean hopper out.
3- Remove the grind adjustment lever. Place index fingers on either side under
the bottom of the lever and pull up from both sides. (for help, see instructions for
adjusting and cleaning the Magic/Royal grinder for illustrations, on this web site).
4- Remove two Torx screws located on the rear edge, under the water tank.
5- Remove two philip screws, under each corner in the front, below the top
cover.
Pull the cover up by lifting it about 1/2" from the back, then move it to the front a
1/2", to free it from the bent edge in the front, the steam knob and the touch pad.
Lift the steam pipe to its top to slide it out through the slot as you lift the top cover
out. 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. If you have
to, then make note of which end you disconnect and where to re-connect the wire
back. Lay the top towards the back of the machine. Now the entire machine is
exposed for open-heart surgery!
To find leaks, look for the obvious white calcium deposits first. For other
malfunctions, machine has to be operated. To operate the machine with the top

removed, a water source has to be connected and the water level sensor
activated (cheated) with a magnet placed next to the location of the level sensor.
To connect the machine with source of water:
1- take the 24" long plastic or silicone tube.
2- disconnect the hose from the water inlet (from under side of the top cover).
3- connect the hoses 1 & 2. Make sure that the connection is air tight.
4- dip the loose end of the extension tube(1) in a clean water container. Make
sure that the tube stays immersed inside the water container all the time.
Replace the brew group. Close the door. Slide the waste box in. Plug the
machine in the electric outlet. Make sure there are no loose wires inside the
machine that were accidentally or otherwise disconnected and there is no
metal object touching the naked wires of the machine, before plugging the
machine into electric outlet. Turn the power switch on. No water sign will come
on.
To remove the no water sign, place the magnet next to the water level
sensor. The water level sensor is a white rectangular piece (1" x 1/2" x 1/4")
located between the water tank and the grinder. Move the magnet around the
sensor, on its left or the rear to find the location where the "no water" light turns
off and leave the magnet clinging at the spot to the metal body of the machine.
You will hear the machine reset as you turn the power switch of the machine on.
Next, prime the machine by opening the steam knob an purging about 2 to 3 oz.
of water. If water does not purge, then check the warning lights on the touch pad
if the machine will tell you why? (No water, no dump box, no brew group light
may be on. If these lights are not lit, then there may be other parts
malfunctioning. It could be the pump, the flow meter or the blocked hydraulic
system that will prevent water flowing through the machine. The machine should
not be left on when water is not pumping through the system. Turn the machine
off. Disconnect the wires to the heating element (tag the loose ends) and wrap
the naked ends with electricians tape. Now the machine can be turned on and
left on for longer duration while other parts are checked for malfunction.
When the pump operates, the water pressure will show the spot where leakage is
occurring. Protect the electronic board from sudden stream of water or
steam spilling on it. Once warmed up, test by making a fake espresso (pre-
ground cycle without adding coffee in the shoot) to see if any leakage of water or
steam can be spotted. Look for the hose connections, seams of heat exchanger,
steam valve, solenoid valves (when seen in the machine) & brass fittings.
Look for any other functional faults and unusual noise during the cycle. To find
leaks, two or more espresso cycles have to be worked.
Replace seals/ O-rings causing leakage. Replace faulty parts as necessary.

If the machine is not heating , check the following:
a- the
thermos
tat (mo
unted
on the
heat
exchan
ger and
steam
boiler if
present
).
b- the
heating
element
(on the
lower
side, not
seen in
the
picture).
c- the
thermof
use
d- the electronic sensor that initially brings water to temperature for espresso.
Finally, before replacing the top cover, make an espresso with coffee. To do so,
use the preground cycle with ground coffee or 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. (Vacuum the spilled beans out)
If all functions are working good, the coffee grind is like the table salt grain, and
still the espresso is not dispensed, the chances are that the
1- pump is weak and unable to exert the pressure necessary to pump water
through the tamped coffee grounds. Replace the pump.
2- the heat exchanger outlet nozzle is blocked or its lower end is broken. Replace
the nozzle.
3- Th brew group is blocked. Clean the shower screen & the valve under the
outlet nozzle flange.
To remove the pump, avoid removing the pump mounting pads (it is a lot of
work).

1- Disconnect the 90 degree plastic water inlet connector from the rear of the
pump.
2- Slide the rear mounting pad off of the water inlet of the pump.
3- With the rear end of the pump free, hold the front brass nozzle of the pump
with pliers and unscrew the front pressure release valve. (Make sure that the
body of the pump does not spin on its outlet nozzle).
4- Remove old O-rings and clean space around o-rings. Use new O-rings. Use
light coating of lube for easy connection without twisting O-rings.
5- Install new pump by reversing the above steps.To connect hoses, slide O-
rings on the hose end first, and wet new O-rings with lube, before inserting.
Use new O-rings on the Teflon hose connections. Replacing O-rings will be easy
if the heat exchanger is taken out from the machine. The heat exchanger is
mounted with only one supporting bracket and two screws.The screws are
visible from inside the door when brew group is removed.
If the heat exchanger is to be replaced, disconnect wires going from heat
exchanger to the electronic board. Make copious notes and take two or three
pictures to remember each wire disconnected from the heat exchanger or the
electronic circuit board. There can be no help available, if a lose wire is left out
without knowing where it re-connects. In such a case the only choice is finding
the path by a lengthy process with an electrical diagram.
