I have a wee fault coming up on my wifes grandmothers boiler. Vokera Unica 28He Code 71, there seems to be a problem when heating up the CH or when running DHW it will run for a while then cut out.. Keeps firing up again then refaulting..
I have purchased a new vokera part for it, just researching how easy it is to change over the wee thermistor.
Anyone know how easy it is to change over. Looks easy enough as the part is located in the airchamber casing. There shouldnt be a need to drain the system surely? .
Like opening a can of worms!!
