Got abit of a problem with this,sometimes if the heater is turned off and the setting is only on "hot water only" the boiler doesnt kick in when the hot water tap is turned on and even with the heaters on it sometimes doesnt kick in when heating ,what can this be?
Very likely the diverter valve
might be still happening - only you wont be able to tell as it take time for them to cool down.
Is that still the case when the heaters in on because im sure is dosnt kick in sometimes when the heaters are running and the combi is only 2 years old! Has anyone got one of these boilers aswell?
