Why does my Glowworm Combi not run hot water?

I have a Glowworm Combi which is very slow to allow hot water through. Initially when the hot water is turned on there is a good flow of water but it’s cold. It doesn’t matter how long the tap is left running, the water remains cold. If I turn down the flow and leave it running very slowly for a while eventually the water will run hot.
