I have a Baxi 80e combi boiler and the hot water will not fire unless the tap is turned on full. Central heating works fine. Any suggestions??

diaphram.
Anyone care to expand on this a little?

The diaphragm is a rubber seal that fits inside the pressure differential assembly.
It pushes a pin onto the microswitch when you turn on the hot water.
If it has a hole in it it may be sruggling to push the pin all the way until you turn the water on full and provide more pressure.
You can get a diphragm for a tenner, I bought one off ebay the other week.
