Chaffoteaux Boiler Fault Codes

Your boiler is struggling to heat your hot water properly, usually because the water is flowing through it too quickly for it to warm up or because the gas supply is restricted.

Your boiler's internal burner is failing to switch off even when you are not using hot water or heating, which suggests a mechanical component is stuck or blocked.

Your boiler is making loud banging or kettling noises because of a buildup of limescale or poor water circulation, which is causing parts to overheat.

Your boiler is struggling to detect the flow of water necessary to ignite and provide you with heating or hot water.

Your boiler is struggling to keep its small starter flame lit, so it has safely shut down to prevent gas from building up.
