sorry its not help but i have the same problem heating fine but 9 out of 10 times no hot water. the red led above the hot water symbol flashes constantly, yet it does ignite at times.??
hi, we have just moved into a house with a heatline vizo combi boiler.
the centeral heating is fine. but the hot water has a mind of its own, some times it does and somes it don't ignite. when it does you have to turn the water down to get it hot then its a fine line between to far it cuts out...
