Hi - Have a fault with a Sime Combi boiler. The Heating and hot water seems to work however i noticed that the boiler keeps firing up thenswitching off. The LED is green whilst running, then switches to orangs and stops. 10-16 seconds later (sometimes longer ) it goes green and fires up again.
I seems to be ok from cold when warming up, it just seems to be when warm. Also when having a shower the water goes hot cold hot cold.
Any Clues
Cheers
