    Hello,

    Thermomix TM5.

    I have a problem with "jumping" values when setting the time, temperature or revolutions.
    Writing graphically:
    I have set the time e.g. 00:10, gently turning the knob should set the value 00:11, meanwhile it jumps to e.g. 00:45, the next turn sets the value e.g. to 01:24 and the next e.g. to 00:15 or 03:43 (there is no regularity, once it jumps down once and up).
    It is the same with temperature and rpm setting.

    Has anyone had a similar problem? What was the reason?

    greetings

    Hello. Undress and lubricate the potentiometer. Unfortunately I did it.

    Hello,

    Should I underestimate something in particular when disassembling TM?
    Alternatively, can a colleague comment on this video, does he present the correct course of action?

    Hey,
    To lubricate the potentiometer you have to completely disassemble the TM5? What is the best lubrication enough for wd40?

    Colleagues, are you sure there is a potentiometer instead of an encoder?
    WD40 I advise against electronics.

    the swab in the film undresses it to a measure properly, screwdriver - torx 5 (I think). The dial is quite an unusual encoder. Absolutely NOT WD40 !! I usually use a thermoplastic preparation for contacts and potentiometers - contact pr ... you want pictures of this part (I recently repaired termomix 5)

    Hello.
    Disassemble the front cover, note the short wires from the "encoder".
    Disassemble the knob (lift it gently!), Under the knob the white ring (it has 2 latches) which you need to unlock and move the white ring to the left. You can then easily get to the entire "encoder". Disassemble 2 plugs and continue working with the "encoder" , clean etc. Thermomix TM5 - jumping values when setting time / temperature / revolutions Thermomix TM5 - jumping values when setting time / temperature / revolutions

    Yes, these are the connections. The wires are terminated with strain gauge beams in the feet of the device. It does not matter where which one is connected. Calibration takes place each time the scale is tared.

Topic summary

The discussion revolves around a malfunction in the Thermomix TM5, where users experience "jumping" values when adjusting time, temperature, or revolutions. Suggested solutions include disassembling the device to access and lubricate the potentiometer or encoder, with warnings against using WD40 for electronics. Users share detailed instructions for disassembly and cleaning, emphasizing the importance of using appropriate lubricants for electronic components. Additional inquiries about wiring and connections on the circuit board are also addressed, confirming that the connections are interchangeable and calibration occurs during use.
