I very rarely see vokeras but came to one yesterday with an intermittent hot water problem running hot and cold. It is passing slightly to the heating and has fairly recently had a new dhw hx. What is a common cause for the fault on this chb?. I have ordered a new thermistor and a new 3 way valve bobbin and sealing washer, reckon I should be looking at anything else?
DP can I draw on your vokera excel knowledge?

ollski...always suspect air flow problems with this boiler. Have you had the fan out to give it a good clean along with the venturi (very common) . On some models the gas valve can be at fault as well (is it going to low gas).
