    I think it's probably about time to give consideration to employing the skills of a qualified electrician/technician to sort out the problems with your machine. We are going around in circles a bit now whereas a qualified person would be able to pinpoint the issue and have it well on the way to being repaired in a matter of hours.

    Where are you located? might give us a hint on type of plugs and sockets you use.
    Is there any measurement between earth and active (L1) and or Neutral (blue wire)? of the cable if it is un plugged both ends?
    so i didnt read my multimeter properly. so the L1 has a value of ''0L' so the resistance is infinite the blue wire also has a value of '0L'. thus the incoming electricity of the switch of the machine is working fine. I also disconnected everything from our machine, the result was that out circuit got tripped.... so the possible issues that i eliminated are:
    Motherboard
    Heater elements
    The pump
    The sensors

    the only thing that i didnt measure is the output of the power switch of the machine. that's the only issue i can think of. i also checked the powerplug for a possible short circuit, but the powerplug also works fine.

    I live in the Netherlands (europe)

    Update: so i measured the power plug and i saw that the "L1" the positive cable( don't know the English term) has the resistance of 0 ohm and the blue wire ( negative cable) 22ohm, so somewhere there is a short circuit being made with the earth leaker

That looks like an Expobar Megacreme 2 group from about 2008-2010. The should draw about 15 amps and has a 15 amp lead. Being a commercial machine it also has a rotary pump which driven by an electric motor which is just below the Gicar box.

    Another thing you could have a look for is any damage to the 240v plugs from a power surge and/or damage to the main switch and terminals where the 240v lead terminates into the machine.

    Your kinda right, but I have enough knowledge to safely work on it. I won't take any risk and i always plug out the power plug if i need to measure something.

    Disconnect one component at a time then recheck with DMM or Megger. Be very careful with electronic black boxes when meggering, easy to damage sensitive components: best to short out all terminals with fuse wire before you commence then remember to remove after testing.

    All the above with power Off and plug removed from the power point of course.

    Trial no and errorw kind of work?, but thanks for the advice!

    I couldn't find the serie number, because our machine doesn't has a sticker with any details on it like serie number etc.

    It looks like this model, but im not sure if its the same model

    Hey thanks for the response!

    I didn't test the main lead yet, because it looked very well isolated. But i will try it!

    I unplugged the in -and outputs. So if you look my 2nd picture you can see 2 green 'blocks' i i pulled those out.

    I don't know if its a 10 or 15 Ampere machine. I couldn't really find any technical specifications of this machine. Is it important to know?

    Wich ​​​​one Is draining more energy the solenoids or the pump? And what kind of pump is it? There is like a ac or dc motor underneath the circuit board, but im not sure if the motor is being used as a pump. Any suggestions on thto test the pump or solenoids?
