Vaillant boiler ecotec plus 824 r1 - controllers dont' seem to work

[gigi75]

hello, i tried to turn the heating on for the first time after the summer break and now the top and bottom left dials in the pict stopped working.


the heating is working, the water though is not warm enough. i want to increase the temperature. is it possible that both the heating and water dials stopped
working at the same time? and why the water was hot until I turn the heating on? the pressure seem to be ok. Is it possible that I changed accidentally something in the settings?

if the controllers stopped working is there a way to increase the water temperature without them?

I just want to avoid to call a plumber for something like that, the boiler is working fine but i need to increase the water temperature, that's all.

cheers!

Not unusual for these dial stems to break,designed that way to protect pcb if dials turned to far round,another great design by the boys from the 'v' sign
come across loads broken thus non operational,new dials requires
imho

but both at the same time isn't it weird?

is there a way to increase the water temperature without those?

Not without going into the pcb,not advised to be done by an unqualified person
