Hi there!
I would like to ask you guys, how should this extra water pump work?
Mine keeps hot water in front of it all the time. I mean the hose from the radiator to the pump is very hot and the one after the pump is cold all the time. The pump is in good working order. It works when connected externally. I do not have the webasto and the REST button.

I am asking this question because my heater stopped working. I also checked the heater valve. It is working.

Thanks!
