My daughter is having a fault on her boiler the system is running (CH and HW). The temp lights run up to 90 then it switches itself off for approx 20 secs then relights for 20 secs then off on off on..etc.
Consequently the rads nearest the boiler get heat the others do not unless they are isolated to receive heat.
I noticed the fill loop was left in the open position (not sure if this has caused a problem) Could it be a thermostat sensor problem, the pump is running ok, the pressure is ok though it was high. System only a couple of years old.
