DeLonghi esam 3000.B EX:1 instant water heater

Hello,
I have a DeLonghi esam 3000.b EX:1 get used gift, but I assume very much that the flow heater is no longer properly heated (coffee not really hot). How can I measure the resistance and what must come out?
With kind regards Sven

Hi,

look times what a heater is installed there. In the EX1 should actually already be the new inside.
If the old one is still installed with the two heating loops, then you can remove the left side panel when looking from the front and then measure the resistance at the two gray cables. One is on the bottom and one on the right, the second from the bottom (F6).

About 40ohms, ok, about 80 ohms is a faulty heating loop.

The instantaneous water heater is the new one with plastic around it.

As a rule, it does not break. You can times thoroughly decalcify with decalcifier on amidosulfonic acid basis. If that does not bring I would replace the temperature sensor.
You can check it, but it may be that the value is ok when cold and no longer fits when the heater is heated.
He should have about 120kOhm at room temperature
