laars endurance no heat

I have a
Laars Endurance combination boiler (EBP). I recently had no heat and no hot
water. The boiler would energize, fire, modulate just a little and then shut off, giving an F4 Error Code. The repair technician changed the flow (supply)
sensor but that didn't correct the problem so they changed the internal or
system pump. Now I have hot water but no heat. Before the technician left he said that he got heat from all three zones in pipes but I get no heat by turning thermostat up. Please can anyone
help??

It sounds like the anticondensing valve is stuck in the closed position.(Or open I forget) Had the actuator go on mine about a year and half ago. It's been running great ever since.
It could also be the valve cartridge itself and not the actuator head.
How old is the unit?
