Hi I've got heating but hot water is not working properly
Won't heat properly
Boiler turns burner off very quickly
I did have a leaky hot water dripping tap for few weeks that's mended now hot water is very poor still
Could that have has anything to so with it ?

if boiler fires up on hot water demand then turns off within a few seconds indicates a possible blockage on the PLATE HEAT EXCHANGER
part number 170995
