Introduction
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.
Parts
-
-
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.
-
-
-
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.
-
-
-
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.
-
-
-
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.
-
-
-
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.
Um „nur“ das Supportventil auszutauschen gibt es noch eine sehr viel einfachere Vorgehensweise. Dabei setzt man an das untere Ende des Supportventils einfach mit einem 7er Gabelschlüssel an und schraubt dieses raus. Bei einigen Modellen wie der Spidem Trevi Chiara gibt es zusätzlich eine Plastikfront um das Ventil, welche sich abhebeln lässt um noch besser an das Ventil zu kommen. Gleichzeitig kann man dann auch am oberen Ende einen 17er Ringschlüssel ansetzen.
