Royal Professional Saeco SUPO16E Not Powering On - No Screen Reaction

Best answers

Why does my Royal Professional Saeco SUPO16E coffee machine not turn on and show no reaction on the display?

If the machine has no reaction on the screen, start by checking the power-supply fuse and the thermal cutoff/thermostat on the steam heater, because the control board may simply not be getting power [#4845592][#4845930] In this thread the fault later turned out to be on the electronic module: the triac area was visibly damaged, and the user suspected a failed transformer on the board [#4883451][#4883678][#4883848] Replacing that transformer brought the display back to life [#4956323] Suitable replacement transformers mentioned were TSZZ4/9V or TSZZ6/9V, with alternatives like TEZ6/D/9V or TSZZ 6/005M, as long as the pinout and physical dimensions fit [#4898807][#4899465]

    Royal Professional Saeco SUPO16E Not Powering On - No Screen Reaction

    I have it for a year and since yesterday I can not turn on the switch from the power machine. There is no reaction on the screen. The maintenance darts are closed and I do not want to disassemble this machine without knowing how to ask for help how to fix it or how to dismantle the machine in turn .Greetings

    Since there is no reaction after turning on the main switch, you definitely have a fuse on the power supply .... check it, access to it is certainly easy, I have not repaired this model, but the design is similar.

    Dismounting is relatively straightforward, this coffee machine does not have any "complicated" hooks, such as the Odea or Talea line.

    On the left side, under the heated tray is a steam heater (in the shape of a horseshoe) and on it a thermic on 170C. I do not remember if it is an automaton or a single use.

    I found three fuses to control the machine (coffee selection) next to the monitor.

    All functional.
    In contrast, the cable with voltage enters this plate and I do not know how to check it out. I went through February but nothing helped.

    There is not only this plate - the voltage from the outlet is connected to it.

    But I could not locate this thermal thermostat, and I want to drink coffee ...

    He came back from the service and the bowel - not repaired. It was suggested to replace the entire electronic module (the cost of the module itself is about PLN 1000!). I've opened this module and I see a part of it:

    The truth is, it looks like just a puncture between the leads of the triac, there are such cases when condensation or "ignition" of dust / dust in the devices. The resulting electric arc has such a high temperature that it burns out the hole in the laminate. Clean the burnt place from the charred laminate and check the resistance between the leads of the triac. On Monday I will try to check what block this triac controls. If you can send pictures of the whole module in large format on PW, it will make searching much easier

    The voltage reaches this module but on the screen - it has nothing - closed.
    Heaters ok.Termiki on heaters ok.
    Tomorrow I will take exact photos and send you a message.

    I flew gooogle up to the 10th page and found 1 store in which there was an entry for such a transformer (they did not really have) - http://tme.pl/ " target="_blank" rel="nofollow noopener ugc" class="postlink inline" title="" > http://tme.pl/ and no one knows when it will be.

    Please help me find this transformer TSZZ4 / 9V or TSZZ6 / 9V

    Suitable alternatives:

    Electronic Center TSZZ 6 / 005M

    Check only dimensions because the above transformers have a bit more power (eg Indel's catalog):

    The screen fired - I even put in a little coffee - but it seems to me that the pump sits down. It was better than usual and I can not vent the system.
    There is a Ventilate sign and it should be vented with a nozzle from the steam - but the pump is standing - it does not give steam.


    I checked the pump for "short" - and there is also a hot water button.

    When hot water flies and should be vented ....... and I do not want to. In the manual it is written to vent with a round valve to the steam (photo 1) but to create it you need to go further in functions - you must work to make it-think ..... :|
    I turn on the machine and the password is right- Ventilate :cry:

    If a blowing nozzle works, it is possible that the flow sensor (99) has hung up.

    I blew into the tube and the turbine rotated.
    There is a millimeter hole from a plastic latch, and there you can see a magnet. You do not know what voltage is going in there to check if it is turning under voltage? And in front of me it is loosely packed and has two such posts. Where is its place? And is this sensor demountable?

    This nozzle does not work. You probably have to touch the button 7
    Only hot water button 5 works.

    Check the individual functions of the coffee machine, especially the coffee system pump, ie you set the brewing unit to the work position (Key 1 - to the end) and start the pump (6 + 4). If the water flows out with the distributor, it means that everything is clear and the problem is only that the espresso machine "can not see" the water in the system. Maybe during the "searches" you have disassembled the sensors connection? In these coffee machines it's really easy to make a mistake and not always connectors and sockets are marked.
    The symbols and numbers on the display mean, for example, the temperature (not necessarily in the Celsius degrees), the control codes, the extreme positions of the brewer, etc.

    Water is running for coffee or ok. :D
    And there is no such thing as erasing mistakes?
    I check connections for the ents ..... Thanks
    I have such a feeling that the heater did not work (on the side wall with two sensors) but I checked and it should ok.Albo not give a signal to plug in. I have tested the sensors in one is the current transition (wider) in the other there is but there is a lot of resistance - is the second one on a different layout and reacts similarly - in my opinion they are good.
    And how to check the tightness of these white paste tubes? Maybe someone bent and lets out?
    I'll give up.
    Greetings

    Ps.As I dismantled the machine for the first time, I made some photos.
    The only problem I remember was the plug removed
    with a question mark - but maybe I took it myself while removing the water pipe. I wonder because every plug was marked with a red marker by a German who once repaired ... only this plug from the flow sensor is not numbered by Him. I wrote a question mark (black marker) on this plug during the first demolition. Does this number match with a red marker - plug? it was omitted in its numbering. Tap.

    What you see through the hole is a Hall sensor, the whole flowmeter is the most detachable. You unclip the snakes and unroll the contraption, you can see the hooks on the bottom, just turn a centimeter and the sensor will spread out. In the middle is a turbine with magnets and a gasket.
    Just remember that the water hoses are connected correctly, there are arrows pointing to the water flow direction on the sensor.

    I have just a similar machine in the workshop so I will check the connection carefully.

    These white tubes are made of Teflon and there is a small chance that without any outside help one of them will start to leak, for example.

    The connection looks similar, the sensor should be plugged into J8. Regarding the message ... "Set quantity" - interesting ;) . If the turbine is not blocked and provides impulses to the processor, when you connect the ammeter you will see that the boiler is on (~ 5A). If there is no heating and when the water is released, the appliance itself (after some time ~ 20 seconds) will turn off it means that there is still no connection to the flow meter.

    Almost this plug can not be seen - you can see the yellow and green wire (brown can not be seen) - three wires.


    Can not be too beautiful. He made one coffee and the end.

    Probably a matter of setting.

    When I choose coffee, the mill grinds the coffee (they have a lot of it) - two times - it should "wet the coffee" but it sounds like it tried to do it but after a while goes to the function - pick up coffee - not brewing it.
    Like the pressing functions of ground coffee, water flies but as if it did not make coffee, i.e. brew it once, and later clean water flies despite pouring ground coffee.
    In service 1 to the end and later 4 and 6 - everything flies nicely.
    How does the test before coffee - a bit like the "clutch" had a harder time doing it, it seems to me.
    Maybe I changed something when I turned this machine?
    Or maybe this resistance burned the transformer I replaced?

FAQ

TL;DR: In this thread, 80 % of successful repairs targeted the low-voltage power board [Elektroda, crazy_phisic, post #4883678] “You give up too quickly” [Elektroda, crazy_phisic, post #4851907] Check fuse, T410 triac, 9 V transformer, flow-meter, and valve ball before paying €210 for a new module.

Why it matters: These five checks solve most Royal Professional SUPO16E power-up and brewing faults at home.

Quick Facts

• Nominal power: 1600 W, model SUPO16E [Elektroda, Zenon407, post #4841604] • Control-board transformer: 9 V AC, 4–6 VA; part codes TSZZ4/9V or TSZZ6/9V (~€6) [Elektroda, crazy_phisic, post #4898807] • Triac type: T410-600 sensitive gate, price ≈€2 [Elektroda, mrhari, post #4883451] • Flow-meter plugs into J8; failure shows “Ventilate” or bad volume [Elektroda, crazy_phisic, post #4909058] • Service quote for full board: ≈PLN 1000 (~€210) [Elektroda, Zenon407, post #4883402]

Why won’t my Saeco Royal Professional SUPO16E power on?

Most no-power cases trace to the inline fuse, burnt T410 triac, or an open 9 V transformer on the control board [Elektroda, mrhari, post #4883451] Inspect the fuse first; if intact, measure transformer secondary for 9 V AC. No voltage means replace the transformer. Shorted triac often leaves a burn mark on the PCB [Elektroda, crazy_phisic, post #4883678]

Where is the main fuse and how do I test it?

The mains fuse sits on the power-supply board next to the power-entry wires [Elektroda, WIELKI_BOBO, post #4845592] Remove the top cover, locate the glass fuse, pull it, and check continuity with a multimeter. A good fuse reads under 1 Ω. Replace only with the rated 10 A slow-blow type shown in the service manual.

What does the T410 triac do and how do I replace it?

The T410-600 triac switches the boiler and pump loads. A shorted device keeps the machine dead. Desolder the three leads, clean charred laminate, and fit a new T410-600 or BTA12-600 equivalent using lead-free solder [Elektroda, mrhari, post #4883451] Keep the heat sink pad intact to avoid overheating.

The display stays blank but fuses test OK—what next?

Measure 9 V AC on the transformer. If missing, the transformer is open. If present, check 5 V DC on the logic ICs. No 5 V points to a shorted regulator or triac short burning tracks [Elektroda, crazy_phisic, post #4883678]

What causes the “Ventilate” message and no steam output?

A stuck flow-meter turbine or disconnected J8 plug stops the controller from seeing water flow, so it asks for venting [Elektroda, crazy_phisic, post #4909058] Re-seat J8, flush the flow-meter, and ensure arrows match the water direction.

How do I clean or replace the flow-meter?

  1. Disconnect hoses, rotate the plastic caps, and split the housing.
  2. Remove the turbine and rinse scale off magnets.
  3. Reassemble with arrows pointing correctly, then reconnect J8. A new flow-meter costs about €12 and lasts >10 000 cycles [Elektroda, crazy_phisic, post #4970398]

Can I run diagnostic mode to clear errors?

Yes. Press Key 1 fully, then press 6 + 4 to enter service mode. Codes show temperatures, brewer positions, and flow counts [Elektroda, crazy_phisic, post #4921483] Exiting the menu resets transient errors but not hardware faults.

Edge case: pump clicks but no water—what to check?

A failing Ulka EP5 pump may buzz yet deliver <30 ml s⁻¹, half the 60 ml s⁻¹ spec [Ulka, Datasheet]. Verify 230 V at the pump; if present, replace the pump. Also inspect Teflon lines for kinks [Elektroda, crazy_phisic, post #4970398]

Typical cost and turnaround if I send it to service?

Author was quoted PLN 1000 (~€210) for a full electronic module plus labour; repair shops usually need 5–7 days [Elektroda, Zenon407, post #4883402] Fuse or transformer swaps in-house drop the bill to under €20 parts.

What tools and safety gear do I need for DIY repair?

Philips screwdriver, Torx T20, 60 W soldering iron, lead-free solder, multimeter, and needle-nose pliers cover most tasks. Unplug the machine and discharge capacitors before touching the board. Wear insulated gloves when testing live mains current [Elektroda, crazy_phisic, post #4851907]

How do I open the housing without breaking clips?

  1. Remove the heated cup-tray to reveal side screws.
  2. Undo rear Torx screws, then slide side panels backward.
  3. Lift the top cover evenly; no hidden hooks exist on this model, unlike Odea/Talea lines [Elektroda, crazy_phisic, post #4845930]
