I have a Necta Koro with water tank. Everything works except hot water.
You hear the pump, but nothing comes.
It happens that after hot water selection then comes the message: "Install boiler".
The message is then also really hard to get away again. Until now I help me then by unscrewing the machine on the left, pull a hose from the pump (I assume edenfalls, that is the pump) and briefly hold my finger on it wärend the machine pumps, so that the thing builds up pressure, then I put the hose back on it and then switch on / off again and the error message is gone. Hot water is then but still not ... Coffee and milk goes 1A.
Anyone an idea?
