NIVONA Caferomatica 830 Coffee Machine: Damaged Display Repair, AliExpress Replacement

Best answers

How can I replace the damaged display in a NIVONA Caferomatica 830 with an AliExpress part?

You usually cannot swap in a random AliExpress display: the original module was a special SSD1303T10, and generic substitutes like BL-12864G2 ERNHn/SPD0301 were reported not to fit or to use a different controller [#17062856][#17833740][#18455044] The practical solution that finally worked was to buy an SSD1305/SSD1305Z OLED module from AliExpress and use one of the adapter PCBs developed in the thread; with the reversal fix, it works like the original and no missing-line problem appears [#18305185][#18233157][#18358600] For the J4rek adapter, the tested parts are C1=C3=100nF, C2=4.7uF, U1=SN74AHC1G00DBVR, U2=CD4071BM, and U3=CD4078BM, and the display is soldered directly to the adapter, which then plugs into the machine’s original 20-pin connector [#18959999][#18279191] If you build the simplified version, the TPS61045 stays on the original board; in the full version it is included on the new PCB [#19025589][#18959999]

    What voltages should be on the board without a display? I have 2.7V, 4.9V and I do not know if the tps system has been damaged because there are no higher voltages.

    Still tiring this display as in April? There should be approx. 12V behind the diode, which goes to soldering point No. 30 of the SSD1305 display or No. 23 of the SPD0301 display.

    Thank you very much: Amigos, Satanist, Smoczy, j4rek and others that they want and deal with such topics.
    Nivona resuscitated and works.
    As PCBs send more, I have assembled and tested more displays.
    If anyone needs it, I will give it back at the cost.

    Such a coffee is a product of Satan - instead of one coffee per week (on Sunday) everyone at home drank 3-4 a day.

    Because the coffee grinder wiped off very quickly in these machines and the coffee was probably weak. I only felt the real taste of coffee when I exchanged heat for a new V5. As I drank the strongest on old ones, then I had to set a maximum of 3 beans because it was too strong. I highly recommend the exchange. The coffee rings must be firm and dry in the container. As they fall apart and you can see that they are coarsely ground, they are coarse to replace.

    Request to measure voltages on U1 61045. I submitted satanistika and darkness from the project, it does not highlight, I type this circuit because it was recovered from an old board, voltages on JP1 inputs are from 5V to 2.9V.

    Hi everyone
    I used the j4rek project and changed it a bit. I want to install an adapter not between DisplayBoard and OledBoard, but on the back of DisplayBoard. It seemed more comfortable to me. The dimensions of the plate are 20 * 35.35. How would you rate it?

    Hello
    We have the same problem with the display, the image began to fade, nothing can be seen. Due to the fact that I do not know electronics, I have no equipment for it, I have a question: would anyone find someone willing, what would my display fix? Please contact.

    Great thread, thanks for all the info! And all the efforts of you guys!
    I guess I'll get a converter pcb manufactured at e.g. Elecrow or a similar company and see if I can get my Nivona operational agian ;-)
    When I want to order the pcb after uploading the Gerber files, I am asked for the size of the pcb. What do you guys use for the size, maybe 35 mm x 20 mm if I look close to the pictures?
    Thanks!

    EDIT: Ah, it shows up after uploading the Gerber files: 17x36mm(0.67x1.4 inches) :-)

    Hello.
    Thank you to everyone involved in this project.
    However, I have one small question.
    I can't find the MOLEX 52745-2490 connector anywhere.
    Can they be replaced with a similar one?

    With regard to the mirroring problem on the SSD1305 Display; decoder77 resolved it by using flash memory sst39vf040. (https://www.eevblog.com/forum/testgear/replacing-oled-screen-on-an-agilent-u1253a-multimeter/msg2438199/#msg2438199). That solution requires pcb and programming the flash memory.

    Is it possible to use the I2C interface on the SSD1305 to force the display to replace the received command from the microcontroller 10100000 to 10100001? Using a $10 ESP32, it may be possible, it needs only 4 wires?

    Great work @j4rek !
    I uploaded the files to a pcb manufacturer and they say that the holes you drew (4 round holes for the plastic poles and 4 rectangular holes for the plastic 'clips') are not indicated for 'cutting out or drilling out' in the Gerber files.
    Because the holes are not indicated in the same layer with the board outline.

    At least that's how they work: ;-)

    Designs about slots/CUT OUT/ millings/ v-cut
    Please kindly make sure that the v-cut lines, cut outs, millings and slots are in the same layer with the board
    outline. If it is not in the same layer with the board outline, it will be missed. So please kindly check it before
    you place your order. If it is missed due to they are not in the same layer with the board outline, we will not
    responsible for it.(lf the slots are to be plated, it needs to be with the drill holes in the same layer, or it will be
    missed easily).

    Would be nice if you could adjust it in the Gerber files!

    Thanks again for all your work!!

    Everything is correct - these holes and cutouts are not in the project because I do not have the original pcb to measure their location accurately. They are merely plotted on the description layer for the approximate location of mounting elements for the black frame.

    In order to add them to the project, I would need a technical drawing with the location and dimensions of the mounts or re-access to the original pcb "EF691" for measurements.

    When I run into another defective Nivona display pcb in future, I will try to make a drawing for you. As I only had one pcb for repair that's already in my friend's machine now ;-)
    Or maybe someone else in the forum can provide the exact measures.

    It works with SSD1305 and the content doesn't blink, there are no errors. When I finish the project I will attach photos. My goal is to solder the circuit on the board to gold pins, separate two gold pins and solder two wires. The whole thing with opening the display took 15 minutes.


    Hello Smoczy,

    it works for me too. However, the entire display flashes. Is this due to the voltage supply of the Step-Up or is it a control signal from the display? Thanks in advance.

    I have read this thread partially. I will say right away, I do not know about it and the display has died for me. I don't know anymore if it can be re-soldered or the display replaced? I am from Warsaw and I would like to have it fixed at a reasonable price. Please advise me what solutions we have at the moment?

    There is no need to program the system / and ask someone for a batch / and uses the original PCB, which is unlikely to break. At least I have not encountered such a case.
    Certainly, someone will come to you with an offer. If you want to repair it yourself, I can help. The most important thing you need is a J4rek board and a proper SSD1305 display. Links to checked from ali are in this topic.

Topic summary

✨ The discussion addresses the issue of a damaged OLED display in the NIVONA Caferomatica 830 coffee machine, with the original replacement cost around PLN 900-1000. Users confirm the original display uses the SSD1303T10 driver and is a 128x64 pixel OLED module with a 31-pin connector, which is now rare and discontinued. Attempts to find direct substitutes on AliExpress or other markets largely failed due to incompatible controllers, pin layouts, or mirrored image outputs. Alternative displays such as BL12864G (yellow OLED) from SOS electronic (Slovakia) and similar models from Japan or Russia have been used successfully but require delicate desoldering and soldering of the 31-pin ribbon cable, a process recommended only for skilled technicians. Some users developed or are developing adapter boards to use newer SSD1305, SSD1309, or SPD0301 controller displays, which have different pinouts and may show mirrored images or missing columns, requiring hardware or firmware adaptations. The community shares detailed disassembly instructions for accessing the display module, emphasizing careful removal of the front panel and soldering challenges. Some users report successful repairs by cleaning pins or replacing capacitors and diodes on the motherboard. The discussion also highlights the scarcity of original or compatible displays, the need for specialized repair skills, and ongoing efforts to create adapters for newer OLED modules to extend the machine's lifespan.

FAQ

TL;DR: Replacing the NIVONA 8xx OLED yourself cuts the 1 000 PLN service bill by ~82 % [Elektroda, paps79, #17062707; jacenty67, #17179483]. “It shines like new” once a SSD1305/0301 panel is fitted. Why it matters: the original display is NLA but affordable substitutes keep the machine brewing.

Quick Facts

• Original OLED: SSD1303T10, 132 × 64 px, 12 V boost rail [Elektroda, amigos, post #17834004] • Proven swaps: SSD1305Z (yellow/white) or SPD0301 (yellow/white), 128 × 64 px [Elektroda, amigos, post #18000551] • Parts cost: 140 – 260 PLN incl. PCB, vs. 800 – 1 000 PLN service module [Elektroda, jacenty67, #17179483; Luczi04031986, #18508253] • PCB options: “Satanistik 24-pin” for SPD0301 or “Amigos 31-pin” for SSD1305 [Elektroda, satanistik, #17894955; amigos, #18233157] • Typical boost voltage after TPS61045: 11 – 13 V DC [Elektroda, jackmc, post #18490466]

Which replacement OLED works without missing pixel columns?

Choose an SSD1305Z 31-pin panel; it shows the full 128 × 64 frame with no two-column gap that affects SPD0301 swaps [Elektroda, amigos, post #18000551]

Why does my SPD0301 screen show a 2-pixel blank strip?

SPD0301 is hard-wired for 128-pixel addressing; NIVONA firmware still sends 132 px data, so columns 0–1 wrap to the end, leaving a visible break [Elektroda, amigos, post #17925365] Functionality is unaffected.

What PCB adapter should I order for SSD1305?

Download the ‘Amigos SSD1305’ Gerber pack (post #18233157) and order 1 mm FR-4, 1-oz Cu; five boards cost about 8 USD delivered from JLCPCB [Elektroda, amigos, post #18510016]

Do I need hot-air to solder TPS61045 boost IC?

Yes. The SON-8 package sits under the board; use 250 °C air, flux, and tweezers. Hand soldering risks bridging pins 6–7 and kills the 12 V rail [Elektroda, damek4, post #18600363]

Edge case: display stays dark after swap—what to test?

  1. Measure VCC at JP1 pins 1-2; it must be 3.3 V.
  2. Check boost output at C4/C10; expect ~12 V.
  3. Inspect TPS61045 for shorts; one bridged pad drops boost to 4–5 V, leaving OLED blank [Elektroda, damek4, post #18600363]

How to flip the mirrored image on SSD1305/0301?

Use the 2-IC inverter: CD4078 combines command bits, CD4071 forces D0 high when opcode A0h is detected, plus 74AHC1G00 adds a 2-gate delay on WR#. Full schematic in post #18507781.

Is a plug-and-play board available?

Yes. Pre-assembled replacement modules appear on eBay for ~90 EUR [Elektroda, amigos, post #18421610] They clip into the 20-pin header—no soldering—yet still use SSD1305 inside.

Statistic: how much money do DIYers actually save?

Forum users report 170 PLN parts + 100 PLN labor versus 900 – 1 000 PLN service, a median saving of 74 % [Elektroda, jacenty67, #17179483; nioop, #17062856].

Can I reuse the old boost inductor and diode?

Yes—if L1 (10 µH, 4532) and D1 (MBR0530) test OK, resolder them onto the new PCB to match NIVONA’s 12 V design [Elektroda, amigos, post #18233157]

3-step How-To: swapping the OLED panel

  1. Unsnap front fascia, desolder 31-pin ribbon, lift old SSD1303 OLED.
  2. Solder new SSD1305 or attach SPD0301 to adapter; fit boost PCB onto 20-pin header.
  3. Bridge D0 (pin 7) per schematic, reassemble, set clock.

What if the new OLED flickers or is dim?

Reflow TPS61045 and check R4 (set to 120 kΩ). An undervalued R4 limits Duty, capping boost at 8 V and causing flicker [Elektroda, jackmc, post #18490466]

Can I order parts locally instead of AliExpress?

Yes. SSD1305Z modules are stocked by BuyDisplay (~24 USD) and Polish sellers (white/yellow, 130 – 160 PLN) [BuyDisplay, 2020; Elektorda, mipix, #18358600]. PCB components are common 0402/0603 passives.

Expert tip for beginners?

“Flux, flux, flux—then the 31-pin ribbon solders itself,” advises user amigos [Elektroda, 18573539] Clean with IPA before final assembly.
