Hi all, i got an problem with my eq7 machine, its happened suddenly a few days ago..
As i was looking for some tips online, i stumbled across this forum, with much tips and topics for such machines. So I hope someone got a solution for this problem, or had an similar experience.

As i was using the milk foamer for warming up water, it stars to push out steam, and only some hot water comes out. The led display becomes foggy. The upper part of the machine becomes really hot after some standby time, theater is not on.
And an boiling noise is to be heard randomly from the inside, as if I'm making coffe or hot water.
The coffee can be made, after witch I turn of the machine completely to not not let it overheat.
I did a decalc, as I though maybe it was clogt somewhere from hard water. But it's still the same after that. The decalcking was also bad, it steamed alot randomly..

I found the maintance option here on the forum. At then I go into components, I see that the heating is going all the time up to 100 C or more. I release then 50ml water, it sinks to about 40-50C then starts immediately to rise the heat again... I tried the factory defaults, but still the same..

I didnt take it apart for now. Someone got some clues or guide what I can do to try and solve it?

Thanks in advance ☺️
