Central Heating

Hot water from combi boiler

My recently serviced Potterton Performa 24 combi boiler has stopped supplying hot water to my kitchen mixer tap on demand unless the central heating is turned up so that the burner flame appears, but there is no problem with the hot water supply to the shower or bathroom hot tap whether the central heating is on or off. Can you identify the problem?
