BoilerFaultCodesTechnical description
domestic hot water cycling mode active
What causes this fault?
This status occurs when the boiler detects that the temperature in the integrated hot water storage tank has dropped below the required level. The boiler temporarily stops circulating heat to your radiators to focus all its energy on reheating the internal cylinder. Once the water inside the tank reaches the correct temperature, the boiler will automatically return to its normal heating schedule.
DIY fix possible
Check your hot water cylinder thermostat settingsEnsure your heating and hot water timers are set correctlyMonitor the boiler to see if it moves to a standard heating or standby mode once the water is warm
