when central heating is on water runs steady hot temp. on hot water only it runs hot for a minute or 2 then goes cold then hot again! no fault codes appear, gas burner lights and goes out then relights again after water temp has cooled, changed hot water temp sensor but no joy... can any one...

boiler runs when no taps are on and heating controls are off radiators start to warm, burner runs for approx 30 seconds goes out then restarts procedure again after approx 10 seconds. 3 way micro switch operates correctly on hot water setting

led code 3 & 4

out of warranty bulk tank buried in ground good gas supply will run properly if thermostat turned down

boiler runs for approx 20 min when hot it locks out with fault , signal loss
