This guide shows you how to replace the thermoblock of a Saeco Royal Classic Sup 014. The replacement is very similar to other models of the Royal-Magic-Stratos series.
These instructions may also help with other Saeco models and with coffee makers from Philips and Gaggia—they are all made by the same manufacturer and have a very similar design.

-
Remove all attachments like water tank, brewing unit etc.
-
-
-
The coffeebean supply is fixed with two screws. Unscrew them and lift it off.
-
There is a black rubber lid under the bean hopper that you can easily lift off, leaving a large opening.
-
The adjuster of the grinder has to be solved. Mark the position or just take a picture. This type is fixed with a screw, others are only sticked together.
-
-
-
There are two screws to be turned out.
-
-
-
The screws are situated on the underneath of the cover. This type is held by four screws.
-
-
-
Now the cover can be raised: first grip on left and right rear side and lift about 10 cm (4 in). Sometimes the cover jams a little bit.
-
Solve the hoses which lead to the water tank. Perhaps you have to pull out some contacts, (e.g. the yellow-green protection lead), don´t forget to put them on again later.
-
The cover can be drawn aslant towards the front, sliding it over the hot water pipe.
-
Most repairs can be done with the cover being laid up partially , it must not be completely removed.
-

-
This is what the removed thermoblock looks like. This one was 14 years old and leaking in various places.
-
-
-
A look into the open device. The thermoblock is hidden under a pile of cables and tubes.
-
-
-
-
It's safer to number the cable connectors on the electronics. You probably just need to disconnect the slightly hidden # 14 connector on the two green cables at the very bottom and # 7 on the blue cable on the top.
-
-
-
The thermoblock is attached to the wall behind the brew group with only two Phillips screws.
-
Remove the two Phillips screws circled in red.

-
-
Pull the clamp on the hose to the steam valve off.
-
Pull the hose circled in orange out.
-
-

Remove the metal holder of the thermal fuse.
-
-
-
Pull first the clamp, and then the second pressure hose out of the thermoblock.
-
-
-
Disconnect the connector with the two gray cables from the thermal switch.
-
-
-
The blue cable from the thermoblock leads to the connector on the electronics, which is marked with 7 here. This particular plug stuck a lot, so force was required to pull it out.
-
-
-
The Allen screw, which holds the holder of the two thermocouples, was not easy to open...
-
Therefore, the plug on the electronics with the two green cables was pulled out. The plug has the mark 14 and is at the very bottom of the electronics.
-
Disconnect the plug with the yellow-green grounding wire from the support valve.
-
-
-
Thread the green and blue cables out.
-
The thermoblock is free. Lift it out of the machine.
-
-
-
Use an allen wrench to remove the screw holding the thermal sensor bracket.
-
Lift off the thermal sensor bracket.
-
Remove both thermal sensors from the thermoblock. Don`t forget to apply thermal paste on reassembly.
-
Pull the connector of the blue wire and remove the thermo fuse cable.
-
-
-
Remove the four Phillips screws holding the support valve in place.
-
Lift the support valve out and set it aside. Pay attention to the connection of the grounding cable so it does not get caught.
-
Follow the steps in reverse order to reassemble your device.
