When I use only hot water, it works, but when I turn on the heater, it goes into blocking mode. I am not satisfied with the after-sales service received from the company. Is it possible to get support from another technician?</FONT></FONT></P><P>&nbsp;</P> Fri, 08 Nov 2024 19:50:29 GMT https://community.viessmann.de/t5/Gas/Brenner-blockiert/m-p/483038#M121265 JRodrigo 2024-11-08T19:50:29Z https://community.viessmann.de/t5/Gas/Brenner-blockiert/m-p/484310#M121448 <P>Hallo,&nbsp;</P><P>&nbsp;</P><P>mal den Wasserstand oder die Pumpe prüfen.</P><P>&nbsp;</P><P>Gruß&nbsp;</P> Tue, 12 Nov 2024 09:07:07 GMT https://community.viessmann.de/t5/Gas/Brenner-blockiert/m-p/484310#M121448 gte1978 2024-11-12T09:07:07Z
