Thanks for the reply.
How do I correctly measure its elelectornic resistance? I haven't used the multimeter on the heatbed.
I still find it strange that it works in the beginning and then stops and works again when I reset the printer.
The bad thing is, that I don't know what thermistor is installed on the heatbed. We bought the heatbed together with an old used 3d printer and moved it to the new printer when we got the new one.

I am close to just buy a new one and see if that one works, those heatbeds are not very expensive.
