I am having some problems with my vaillant aquaplus vui 362-7 combi boiler, When hw tap is continusously opened the dhw temp exceeds the set temp by the dial by long way
It appears there is a problem with DHW upper limit setting, perhaps the PCB does not see it
The above lead me to examins the d codes, and discovered the d50 shows 113 oC
Can any one help to resolve this ?
