About 9 years old Worcester Bosch combi 24cdi rsf
. HW light was flashing fast. Reset red button and works again. However i noticed that the pressure clock is now at about 2 when it has always between 1 and 1.25. Also, regarding Hot Water demand, the Boiler will only fire up when the water flow at the tap is at at least medium flow and even then it is very hot. At a reasonable low flow , the boiler will not fire. Any ideas ? (The water pressure in this house has always been high )[/u]
