Anyone know the problem with my boiler the symptoms are: when drawing off hot water the gas ignites for a short period of time and then the gas suddenly stops. Heating is ok gas works continuously with the heating.
No flashing warning lights water pressure is ok

Could be a faulty diverter valve or a blockage in the plate heat exchanger. This would stop the flow of the primary water around the boiler and result in the water going to the hot taps not heating up and it may not throw up any error codes as a result.
